Authors:G. Srinivas, G. Durga Sukumar Pages: 267 - 289 Abstract: In indirect vector control, the conventional speed and current controllers operate satisfactorily when the operating point is constant. But the operating point is always dynamic; the reference voltages obtained in a closed-loop system feeding to the inverter contains more harmonics. Due to this, the pulses which are going to produce are uneven and in turn, understudy creates the inverter output voltages produced with more harmonics. In order to produce a better output voltage from the inverter, this paper presents the neuro-fuzzy type-2 (NFT2) space vector modulation technique. Performance comparison of the inverter is done with conventional space vector modulation (SVM) and neuro-fuzzy type-1 (NFT1) system using MATLAB simulation and experimental validation. The performance parameters of the induction motor based on current, torque, and speed with neuro-fuzzy type-2 space vector modulation is compared with conventional and type-1 neuro-fuzzy SVM. The % THD of inverter output voltages are also compared. The experimental validation of a DSpace-1104 is used to analyse the performance of the induction motor which is obtained by the simulation. The experimental validations are carried out considering 2HP induction motor in the lab.

Authors:Yatindra Gopal, Kaibalya Prasad Panda, Dinesh Birla Pages: 290 - 308 Abstract: The elimination of harmonics and need of a large number of switches in multilevel inverters (MLIs) have been the focus of research from the last few decades. This paper reports the analysis of a 1-ɸ 7-level cascaded multilevel inverter (CHB MLI) and a new reduced switch MLI (RS MLI) using genetic algorithm (GA) and anti-predatory particle swarm optimisation (APSO) technique. To improve the output voltage quality, switching angles are evaluated using the GA and APSO techniques. The pluses generated based on the switching angles are further used for controlling the MLI. A comparison with recently developed MLIs is conducted to confirm the merits of the developed RS MLI. MATLAB software is used for simulation of the both the topologies, i.e., 1-ɸ 7-level CHB MLI and a 7-level RS MLI. Theoretical results are finally verified by developing a prototype in the laboratory.

Authors:Nitesh Tiwari, Shekhar Yadav, Sabha Raj Arya Pages: 334 - 350 Abstract: This paper will demonstrate the viability of neural network algorithm for solving power quality problems in three-phase neutral-point clamped converter. A neural network algorithm is proposed here for the better performance of the converter under perturbed conditions. The neural network algorithm modifies conventional space vector pulse width modulation algorithm. The proposed algorithm generates ideal switching sequences for the converter by developing the best path for the reference vector in the hexagon of the space vector. The data set required to train the neural network was collected from well tuned PI controlled model. In this work, the implementation of neural network is described and simulation results are presented using MATLAB/Simulink software. Simulation results proves fast minimising the potential difference at the clamped bus of the converter with minimum switching losses and excellent performance of converter in terms of unity power factor, better total harmonic distortion at the source side.

Authors:Neethu Elizabeth Michael, Shazia Hasan Pages: 351 - 395 Abstract: This paper epitomises the various aspects of virtual inertia using energy storage systems for satisfactory regulation against uncertain frequency and voltage fluctuations. Since the power system switches from a generator-dominated system to an inverter-dominated system it results in the culmination of lack of inertia due to the massive penetration of renewable energy resources. This eventually leads to problems of frequency stability and power quality. The principle of virtual inertia, which emulates the operation of the synchronous generator by providing the power system with inertia remotely, was a topic of research from 2007 and is now gaining recognition. Software simulations and hardware implementation will open the way for a thorough investigation of the technology in the future. Furthermore, it also addresses the different types of virtual inertia topologies, application with renewable energy sources, evaluation for ancillary services, potential opportunities, risks posed, and future research directions.

Authors:Soumya Ranjan Das, Prakash K. Ray, Debani P. Mishra, Himansu Das Pages: 396 - 417 Abstract: The role of predictive controller in recent days is found to be vital in controlling the voltage source inverter (VSI) of the active power filters (APF). It is realised that, the improvement of power quality (PQ) in the utility network using nonlinear loads, with integration of renewable sources, has become an open challenge to the researchers. This paper proposes an integration of photovoltaic (PV) system with three phase power distribution system using series hybrid filter (SEHF). The objective of the paper is to reduce the harmonic components and dc link control of VSI for improving the PQ and simultaneously provide uninterrupted supply to the load by compensating the reactive power. In this work, the fuzzy logic controller (FLC) is employed for maximum power point tracking (MPPT) in a PV system and a model predictive controller with robust extended complex Kalman filter (MPC-RECKF) technique is applied for calculating the fundamental components from distorted value in SEHF. The results obtained using the proposed MPC-RECKF is compared and analysed with traditional controllers in MATLAB/SIMULINK environment.

Authors:Manmadha Kumar Boddepalli, Prema Kumar Navuri Pages: 418 - 442 Abstract: In this paper, a new tilt integral derivative (TID) controller is implemented for a multi-area multi-source power system. The parameters of the TID controller are optimised using a firefly algorithm (FA) and it is employed with integral time multiplied absolute error (ITAE) as an objective function. Initially, three-area nine-unit power system is designed in MATLAB/Simulink environment. The superiority of the proposed controller is established by comparing simulation results Ziegler-Nichols (ZN)-based PID and FA-based PID controllers for the same designed model. The simulation results reveal that frequency responses and tie-line power deviations are enhanced with FA-based TID when compared to ZN and FA-based PID controller. Finally, the effectiveness of the proposed controller is examined by doing robust analysis under varied system parameters.

Authors:Srishti, Prerna Gaur Pages: 443 - 472 Abstract: Microgrid-based energy management system (EMS) is designed and implemented in this paper to manage the energy balance between renewable resources and the load, i.e., supply-demand balance of energy. Wind energy generation is done through PMSG using the method of vector control of synchronous generator. Further, the investigation of modelling and control of state of charge (SOC)-based battery management system (BMS) in microgrid for autonomous/islanding mode is presented in the form of aggregated battery model. Since BMS is critical in maintaining the optimum performance of battery and hence, a battery system has been designed in the present work. The results of the comparative study of the proposed MPPT techniques, i.e., CSA, ANN, FLC with conventional P&O using MATLAB/SIMULINK in terms of accuracy, electric power efficiency, duty cycle, DC link voltages, and load power of proposed techniques are presented in the present work. The working of the proposed EMS for hybrid PV-wind-battery system is verified through simulation results using various control algorithms.

Authors:Sachin Angadi, Udaykumar R. Yaragatti, Yellasiri Suresh, A.B. Raju Pages: 473 - 494 Abstract: In small scale, stand-alone, wind-power generation employing self excited induction generator (SEIG), water pumping using an induction motor is a typical application. In this paper, a simple voltage regulation scheme for the constant flux operation of the inverter assisted SEIG feeding three-phase induction motor pump is presented. The behaviour of DC-link voltage, frequency, amplitude modulation index (<i>m<SUB align="right">a</i>) and the shaft speed for load and speed perturbations are discussed in detail. Also, the overall active and reactive power flow for constant flux operation at the point of common coupling (PCC) is analysed. The proposed work presents a simple and reliable controller for SEIG-based stand-alone system for frequency-dependent loads using only a DC-link voltage sensor. Detailed system simulations are performed using Matlab/Simulink and the results of a laboratory prototype are presented to validate the theoretical analysis and practical operability of the proposed system.

Authors:Thouraya Guenenna, Khaled B. Smida, Adel Khedher Pages: 495 - 521 Abstract: This article deals with the determination of the multi-stars induction machine (MSIM) equivalent circuit parameters based on the geometrical and electrical data using two methods namely analytic and finite element method (FEM). Additionally, this paper proposes a general dynamic study of MSIM. This latter is fed by a multi-phase inverter (MPI) controlled by a space vector pulse width modulation (SVPWM) and a sinusoidal pulse width modulation (SPWM). However, when this machine is fed by the voltage inverter for the case of 30° electrical shift between stator stars, large harmonic currents are observed. Thus, the main goal of this paper is to reduce the effect of these harmonic currents. Therefore, to overcome these issues, the machine stars number has been increased to three and four and the inverter has been controlled by the SVPWM. The effectiveness of this association and its capability to reduce the effect of the output harmonic current and electromagnetic torque ripple has been proved by simulation results.

Authors:Nitin Gupta, Sandeep Banerjee Pages: 522 - 547 Abstract: This work proposes a practically feasible and distinct method of harvesting wind energy for urban and rural rooftops. This technique is especially useful for distributed generation. A one-fourth scaled version of a new type of wind energy conversion system (WECS) has been presented. The novelty of the reported WECS lies in the usage of a magnetically levitated vertical axis wind turbine (VAWT) along with dynamic guide vanes system. The usage of magnetic levitation results in loss minimisation and efficiency maximisation. To tap maximum wind energy, the guide vanes are programmed to dynamically change their angle according to the wind speed. This paper also presents the utility of an axial flux permanent magnet (AFPM) generator for VAWT systems. An experimental model has been developed and its results have been presented. The experimental results have been put to use for developing a model of the VAWT system using fuzzy inference system (FIS).
