      Abstract: Abstract This work intended to build a mathematical model for a designed, constructed and tested clean, transportable and comfortable advanced biomass cookstove. The system was subdivided into 31 isothermal subvolumes (nodes), interconnected to one another by thermal resistances corresponding to a particular type of heat transfer. A differential system of 31 equations governing the heat transfer in the ovens’ configurations was obtained, and numerical simulations were carried out in order to appreciate the thermal behavior of the systems. A validated data acquisition device (device SAG) for controlling the thermal behavior of stoves or heating systems was used for experimental studies. The numerical results were in agreement with the experimental results and needed a low computational time.

  • Resilience enhancement of distribution grids based on the construction of
           Tie-lines using a novel genetic algorithm

    • Free pre-print version: Loading...

      Abstract: Abstract The occurrence of unfavorable weather conditions and natural disasters has always led to the imposition of extensive damages and outages at the level of distribution networks; that the number and severity of these events in recent years have often been increasing. Therefore, evaluating the resilience of the network and its reversibility ability in the face of natural disasters should be among the planning priorities for the design and operation of the network. The idea of this article is presented based on constructing the Tie-lines between the damaged sections of the network and healthy of the network in the event of a possible incident to return the service to the parts of the network without power. Finding an effective method to provide an optimal scheme to electrify the damaged parts with the lowest cost is one of the challenges of this research. Therefore, the genetic algorithm based on the elitism mechanism is proposed as one of the efficient evolutionary algorithms to optimize the total cost function, including the cost of constructing Tie-lines, the cost of reliability, and the cost of resilience. The proposed method has been applied to a feeder from the test network, and its superiority is presented through comparison with other evolutionary methods used in this study, such as particle swarm optimization and shuffled frog leaping algorithm.

  • Optimization of a domestic microgrid equipped with solar panel and
           battery: Model Predictive Control and Stochastic Dual Dynamic Programming
           approaches

    • Free pre-print version: Loading...

      Abstract: Abstract In this study, a microgrid with storage (battery, hot water tank) and solar panel is considered. We benchmark two algorithms, MPC and SDDP, that yield online policies to manage the microgrid, and compare them with a rule based policy. Model Predictive Control (MPC) is a well-known algorithm which models the future uncertainties with a deterministic forecast. By contrast, Stochastic Dual Dynamic Programming (SDDP) models the future uncertainties as stagewise independent random variables with known probability distributions. We present a scheme, based on out-of-sample validation, to fairly compare the two online policies yielded by MPC and SDDP. Our numerical studies put to light that MPC and SDDP achieve significant gains compared to the rule based policy, and that SDDP overperforms MPC not only on average but on most of the out-of-sample assessment scenarios.

  • A novel PSO algorithm for DG insertion problem

    • Free pre-print version: Loading...

      Abstract: Abstract Distributed Generation Units (DGs) are an effective solution to the power loss problem of the distribution network, which increases at peak demand. Also, it helps to meet consumer demands and needs. Many optimization algorithms have been applied to achieve the optimal location and size of DG units. Although this technique reduced active power loss, it has several problems, such as complexity, accuracy, and premature convergence to a local optimum. This work aims to improve the performance of the distribution network by considering the minimization of active and reactive power loss, reducing the voltage deviation, and finding the solution in a shorter time. Therefore, an improved Particle Swarm Optimization (PSO) algorithm is suggested to solve the problem of convergence at a local optimum. The proposed algorithm considers DG units that produce only active power. Two test cases are used to validate the performance of our proposed technique: an IEEE network with 33 nodes and another with 69 nodes.

  • A review of the applications of machine learning in the condition
           monitoring of transformers

    • Free pre-print version: Loading...

      Abstract: Abstract Power transformers are critical components of every power system. They are expensive apparatuses accounting for a significant portion of the capital investment in the electric power system. Several monitoring systems and diagnostic approaches have been developed over the last few decades with the common goal of increasing the operating life of power transformers and reducing the possibility of catastrophic failures. However, some challenges need to be addressed before effectively interpreting measurement data gathered from these techniques and making specific judgments about the transformer condition. Machine learning (ML) as a principal class of artificial intelligence (AI) is a suitable solution to this problem, and it has recently intrigued the interest of many researchers. In this regard, the present paper reviews the literature and analyzes the latest techniques included while highlighting the advantages and disadvantages of current methodologies. Also, intelligent fault diagnosis methods and the most widely used intelligent algorithms in evaluating the condition of transformers are presented. The methods discussed in this paper are useful for diagnosing both power and distribution transformers. Finally, potential solutions are proposed, and future research directions are suggested.

  • An optimal placement and sizing of type-IV DG with reactive power support
           using UPQC in an unbalanced distribution system using particle swarm
           optimization

    • Free pre-print version: Loading...

      Abstract: Abstract Three-phase distribution system normally works in unbalanced nature every time especially when it is three phases four-wire system, the system becomes more complex when DG is incorporated in an unbalanced system because the power quality decreases and may damage the equipment. This paper presents an optimal placement and sizing of Type IV i.e. induction generators in large wind farms and their amalgamation in an unbalanced distribution system with reactive support using UPQC (unified power quality conditioner) using particle swarm optimization (PSO) for loss minimization. The size of DG is determined by the penetration level and here the penetration is kept under 12% to avoid too harsh tripping of the circuit breaker. The power loss may be decreased using the iterative PSO method. On unbalanced IEEE 34 and 123 bus systems, the suggested method is examined. The simulation results demonstrate the technique’s remarkable suitability and adequacy.

  • A coordinated stochastic dispatch model for hybrid energy markets with
           renewable energy uncertainties using moth flame optimization

    • Free pre-print version: Loading...

      Abstract: Abstract Currently, the deployment of renewable energy sources (RESs) is rapidly increasing in transactive energy markets (TEMs). The effects of RES uncertainties on transactions and power markets are increasing with the penetration of RESs into the system. The integration of RESs into TEMs brings new challenges to the security and economic operation of the power markets and also makes significant changes in the scheduled transactions and economic dispatch of power generation units in the power markets. Therefore, it is important to manage RES uncertainties and reduce their impacts on transactions as well as conventional generation units for the secure and economic operation of TEMs. This paper proposes a coordinated stochastic dispatch model for the optimal dispatch of transactions and conventional generation units without any security and economic issues in TEMs considering RES uncertainties. In this work, the penalty cost of transactions and the rescheduling cost of power generations are incorporated with the proposed dispatch model to reduce the variations in scheduled transactions and power outputs of generation units. For more effective analysis of the impacts of RES uncertainties on transactions in terms of their scheduled sizes, three new indices are introduced in this work. Based on the information provided by these indices, the system operators or power traders can take suitable/appropriate actions for the secure and economic operation of TEMs against RES uncertainties. In the proposed model, the stochastic nature of solar and wind units is modelled by using the Weibull distribution function. A modified IEEE 57-bus system has been adapted to illustrate the performance of the proposed dispatch model. The optimal solutions of the proposed dispatch model are determined using the Moth Flame optimization algorithm.

  • Design and feasibility analysis of grid-connected hybrid renewable energy
           system: perspective of commercial buildings

    • Free pre-print version: Loading...

      Abstract: Abstract Green energy technologies have been widely acknowledged as a supplement to conventional power sources due to the finite nature of fossil fuels, ever-increasing load demand and GHG emissions. This paper proposes a HRES that encompasses photovoltaic, electric vehicle, battery system and grid. The viability analysis of the HRES is implemented in this paper by using the load profile of Tucson Mall, U.S. and the meteorological data from the NASA. This study seeks to create a framework for sustainable energy that enhances the performance of the conventional power system by reducing the NPC, payback period, GHG emissions, COE and energy obtained from the grid by using HOMER application. The NPC, COE, payback period and return on investment for the best configuration of the proposed HRES are $1,600,623.00, $0.0420, 4.10 years and 19.0%. The outcomes of the study demonstrate that the most feasible configuration achieved 60.38% of COE and 39.48% of NPC better than case study 1. The optimal HRES has been subjected to a sensitivity analysis to establish the influence of several parameters such as interest rate, load demand, capital cost, inflation rate, solar radiation and temperature on the COE and NPC. The findings of the study demonstrate that the PV system plays an important role in decreasing GHG emissions, NPC and COE as well as achieving the optimal operation of the HRES. The incorporation of green energy technologies into the utility grid can sustainably address the global energy crisis and improve access to electricity. The government agencies can use the findings of this study as a crucial step in increasing the proportion of green energy technology in the global’s energy mix.

  • Efficient mathematical models for parameters estimation of single-diode
           photovoltaic cells

    • Free pre-print version: Loading...

      Abstract: Abstract The photovoltaic (PV) cell behavior is characterized by its current–voltage relationship. This relationship is dependent on the PV cell’s equivalent circuit parameters. Accurate estimation of such parameters is essential to study and analyze the PV system performance in terms of many aspects such as modeling and control. The main purpose of this paper is to develop mathematical models for the parameters of the single-diode poly and monocrystalline PV cells. The models are formulated using Eureqa software by utilizing training data collected from simulating thousands of PV modules available in Simulink library. The developed models can be easily and instantly executed by only using information available from module datasheet under standard test conditions (STC). The models are then validated using four different assessments by considering testing data, commercial PV modules, and experimental data, in addition to benchmarking with other reported algorithms. As an overall evaluation, the assessments have shown that the developed models are efficient in estimating the PV cell equivalent circuit parameters and can consequently predict the I–V curves for any poly or monocrystalline PV modules, under any weather conditions, with a high degree of accuracy.

  • A novel theta MPPT approach based on adjustable step size for photovoltaic
           system applications under various atmospheric conditions

    • Free pre-print version: Loading...

      Abstract: Abstract This study suggests and discusses a new maximum power point tracking (MPPT) approach based on an adjustable step size for photovoltaic system applications to extract the real MPP under various atmospheric conditions. The suggested adjustable step size Theta approach (ASSTA) is essentially based on the Theta angle (θ), which is the arctangent of the change in photovoltaic power derived by the variation in the photovoltaic voltage (arctan(dPpv/dVpv)) and its derivation in relation to the change in the photovoltaic voltage (dθ/dVpv) with the use of a new adaptable step size (dPpv + dVpv × dIpv). MATLAB/Simulink® software is selected for the implementation of the overall photovoltaic system, and the simulation results in different scenarios indicate that the novel ASSTA guarantees a fast convergence speed to the real MPP under a rapid change in operating conditions (insolation and temperature) with a time fewer than 0.017 s. Furthermore, the ASSTA shows better accuracy in tracking the MPP in the case of sudden insolation and temperature change and tracks the real MPP with neglected fluctuation in steady-state operation. Its average tracking efficiency in all simulation scenarios can be between 99.10 and 99.81%. Additionally, in light of the comparative simulation results of the new ASSTA with other methods such as INC, P&O, variable step size INC (VSSINC), and PSO MPPT techniques under various climatic scenarios, it can be concluded that the novel ASSTA outperforms the other MPPT approaches and significantly boosts the tracking performance and reduces power loss.

  • The network of commodity risk

    • Free pre-print version: Loading...

      Abstract: Abstract In this paper, we investigate the interconnections among and within the Energy, Agricultural, and Metal commodities, operating in a risk management framework with a twofold goal. First, we estimate the Value-at-Risk (VaR) employing GARCH and Markov-switching GARCH models with different error term distributions. The use of such models allows us to take into account well-known stylized facts shown in the time series of commodities as well as possible regime changes in their conditional variance dynamics. We rely on backtesting procedures to select the best model for each commodity. Second, we estimate the sparse Gaussian Graphical model of commodities exploiting the Graphical LASSO (GLASSO) methodology to detect the most relevant conditional dependence structure among and within the sectors. A novel feature of our framework is that GLASSO estimation is achieved exploring the precision matrix of the multivariate Gaussian distribution obtained using a Gaussian copula with marginals given by the residuals of the aforementioned selected models. We apply our approach to the sample of twenty-four series of commodity futures prices over the years 2005–2022. We find that Soybean Oil, Cotton, and Coffee represent the major sources of propagation of financial distress in commodity markets while Gold, Natural Gas UK, and Heating Oil are depicted as safe-haven commodities. The impact of Covid-19 is reflected in increased heterogeneity, as captured by the strongest relationships between commodities belonging to the same commodity sector and by weakened inter-sectorial connections. This finding suggests that connectedness does not always increase in response to crisis events.

  • Effect of modelling choices in the unit commitment problem

    • Free pre-print version: Loading...

      Abstract: Abstract In power system studies the unit commitment problem (UC) is solved to support market decisions and assess system adequacy. Simplifications are made to solve the UC faster, but they are made without considering the consequences on solution quality. In this study we thoroughly investigated the impacts of simplifications on solution quality and computation time on a benchmark set consisting of almost all the available instances in the literature. We found that omitting the minimum up- and downtime and simplifying the startup cost resulted in a significant quality loss without reducing the computation time. Omitting reserve requirements, ramping limits and transmission limits reduced the computation time, but degraded the solution significantly. However, the linear relaxation resulted in less quality loss with a significant speed-up and resulted in no difference when unserved energy was minimized. Finally, we found that the average and maximum capacity factor difference is large for all model variants.

           optimal energy balance in microgrid considering islanded conditions

    • Free pre-print version: Loading...

      Abstract: Abstract The energy balance in islanded microgrids is a complex task due to various operational constraints. This paper proposes a new approach to multi-objective optimization for achieving energy balance in a Microgrid (MG) in both islanded and normal modes. Optimal load control (OLC) is a challenge, due to a lack of capacity to generate the global optimum after each run. The latest variant of Teaching Learning Based Optimization (TLBO), known as Adaptive-TLBO, includes both modifications during exploitation and exploration stages (ATLBO). The results achieved with the proposed method are exceptional on a modified IEEE 33-bus system. In addition to the improvement of the voltage profile and the decrease of the distribution losses, the energy balance improves with the method. The proposed ATLBO algorithm overrides any proposed other algorithm, as shown by comparison with PSO, base TLBO, Backtracking search algorithm (BSA) and cuckoo search algorithms, etc. (CSA).

  • Robust optimal sizing of a stand-alone hybrid renewable energy system
           using dynamic uncertainty sets

    • Free pre-print version: Loading...

      Abstract: Abstract This paper presents an adaptive robust approach for optimal sizing of a stand-alone hybrid renewable energy system (HRES) composed of wind turbines, solar photovoltaic panels, a battery bank, and a diesel generator. Unlike classical robust HRES sizing models that capture the unpredictable nature of renewable energy sources through static uncertainty sets (SUSs), we use dynamic uncertainty sets (DUSs) that account for the temporal auto-correlations in the wind and solar energy outputs. The DUSs are constructed based on time series models selected through a statistical framework to have the best description of the wind and solar energy output behavior. An iterative algorithm based on column-and-constraint generation is developed to solve the adaptive robust problem efficiently. The proposed model and solution method are tested on a realistic case study of an isolated community in northern Ontario, Canada. The superiority of the proposed approach compared to a ARO with SUSs model, and a nominal model that uses point estimates of the parameters is demonstrated by simulating the system operation using real test data, highlighting the need to account for the auto-correlations in data while considering supply and demand uncertainty.

  • The error induced by using representative periods in capacity expansion
           models: system cost, total capacity mix and regional capacity mix

    • Free pre-print version: Loading...

      Abstract: Abstract Capacity Expansion Models (CEMs) are optimization models used for long-term energy planning on national to continental scale. They are typically computationally demanding, thus in need of simplification, where one such simplification is to reduce the temporal representation. This paper investigates how using representative periods to reduce the temporal representation in CEMs distorts results compared to a benchmark model of a full chronological year. The test model is a generic CEM applied to Europe. We test the performance of reduced models at penetration levels of wind and solar of 90%. Three measures for accuracy are used: (i) system cost, (ii) total capacity mix and (iii) regional capacity. We find that: (i) the system cost is well represented (~ 5% deviation from benchmark) with as few as ten representative days, (ii) the capacity mix is in general fairly well (~ 20% deviation) represented with 50 or more representative days, and (iii) the regional capacity mix displays large deviations (> 50%) from benchmark for as many as 250 representative days. We conclude that modelers should be aware of the error margins when presenting results on these three aspects.
