Authors:Ayşe KOCALMIŞ BİLHAN; Serenay EMİKÖNEL Abstract: The electricity which is generated from the photovoltaic (PV) module needs a couple of requirements for utilizing. Firstly, the PV module should work in maximum power point, and secondly, it is needed a power conversion unit. To calculate to Maximum Power Point (MPP) of a PV module or array, solar radiation, ambient temperature, cloudiness ratio, and even wind speed have to be considered. In this paper, the duty cycle of the power conversion unit has been calculated by considering solar radiation. In these calculations, a conventional method which is perturb and observation (P&O), and another approach which is fuzzy logic control (FLC) were studied and compared by using MATLAB/Simulink.

Authors:Kıvanç DOĞAN; Ahmet ORHAN Abstract: In this article; The step-by-step design of a 3-phase salient synchronous generator and efficiency optimization with particle swarm optimization technique are investigated. Unlike other studies in the literature, a system has been studied to minimize mathematical equation errors by using specific loading parameters that simplify the design process. It has been tried to obtain a program structure that minimizes programming problems by minimizing the number of variables used in the design. With the optimization of the specific loading parameters, the effects on the machine volume, cost and efficiency were examined. PubDate: Tue, 27 Dec 2022 00:00:00 +030
Authors:Obed Nelson ONSOMU; Bülent YEŞİLATA Abstract: A Virtual Power Plant system is an advanced power distributing and trading platform, that acts as a smart grid system unlike the existing conventional methodology of power allocation. The system is known to facilitate the connection of renewable energy sources to the national grid from a specific region, it is made up of Energy Storage System, Distributable Energy Resources, and Control System. Energy sources are classified as Distributable Energy Resources and various assets can be linked to the platform such as small-scale microgrids or community-based power platforms with demand-side management portfolios. A Virtual Power Plant platform has the power-distributing capability and an evolutionary trading platform (Peer to Peer trading). It has also proven to cut down carbon emissions as more renewables find their way to the grid. Additionally, data analytics and forecasting tools on the Virtual Power Plant are used to give information to the end-users on their storage, demand, and expected future generation, the user can interact with the system through a Human Machine Interface that has easy to use dashboard. Currently, the VPP systems have been implemented as pilot programs in countries such as Sweden, Norway, Belgium, and the USA. The potential application of the system can be extended as a case study and futuristic smart grid system for Kenya, as the National grid is substantially fed from renewable energy sources, and the vast majority of rural areas can benefit from cheap and affordable energy. Finally, Virtual Power Plants are proven to be reliable systems, and power outages and delays can be minimized. PubDate: Tue, 27 Dec 2022 00:00:00 +030
Authors:Aıdın ARMANFAR; Mahsa KHANMOHAMMADI Abstract: As a result of the energy crisis of fossil fuel in the world, and pollution that comes from using these types of fuels, humans need to find clean and affordable energy to survive, impelling communities which produce their energy to carry out new initiatives. The use of wind, water, earth, solar and other clean energy has become possible, and finally, the world is on a path that requires new research in this field. Between the urban and social elements, per capita energy in the housing sector is allocated the highest consumption in the world, and this sector has the greatest amount of energy consumption in Iran as well. Researchers are presenting new solutions in addition to the usage of technology in the production of renewable energies, making closer to reality the reproducible ideas about using parts of buildings and natural forces around the buildings. This study is an attempt to explore the surrounding natural forces and materials that are used in construction, alongside the study of books and valid and scientific global websites that discussing the idea of using new technologies along with the existing energy production. Using renewable energy, homes have been made from special materials, where the manner of design adjusts to the environment (like solar energy), but can still function in any condition. We have seen that by studying the available information, biogas and photovoltaic systems are also intended to (in addition to their own sufficiency) and lead to saving energy. The day is coming that single municipal buildings will manage to make their fossil energy usage reach zero. PubDate: Tue, 27 Dec 2022 00:00:00 +030
