“…For a roof area of 400 m 2 , the optimum PV power is simulated as 30 kW and the optimum wind turbine power is simulated as 22.5 kW. According to the simulation results, it is seen that 55% of the annual energy demand of the building can be met, with 23% PV panels and 32% with wind turbines [16]. In a study simulating the PVGIS interface and comparing the results with the real electrical energy production values, it was seen that the simulation results were realized with a 5% error from the actual production results [17].…”

The use of electrical energy from renewable energy sources has increased considerably in recent years. Photovoltaic (PV) solar energy, which is one of the renewable energy sources, takes its source from the sun, which is considered an unlimited source. With the widespread use of photovoltaic systems, some legal regulations by governments have been made for their installation. Simulation programs are used for the design, layout, technical and economic analysis of PV systems. In this study, the design was made using the PVsyst, PV*SOL, Solarius programs, and the PVGIS website used in PV systems. The projects are designed to have an output power of 25 kW. According to the simulation results, the PVGIS website provides approximate data, since technical details cannot be entered. In the results of PVGIS and all simulation programs, it has been calculated that the system can produce 42-48 MWh of electrical energy annually. Power Ratio (PR) results of the system were in the range of 78-85%. Annual electrical energy production per installed kW has been calculated to be 1436-1635 kWh/year. It is stated that the annual saved CO2 will be 18.66-22.226 tons /year. When the simulation results are analyzed monthly, the differences between the months are remarkable. The reason for these deviations can be explained by the annual solar radiation (kWh/m2) data and databases used by the programs. It has been observed that the simulation programs consider the monthly average temperatures and sunshine durations of the region. It is thought that there is a need to compare real-time data with simulation results in future studies. It is considered that this study will be helpful for future studies.

“…All these components manifest as harmonics/high frequency interferences with varying amplitudes and consequences. These harmonics usually disrupt or destroy the operation of converters and other micro grid-connected devices [4], [9]. Currently, no limits are imposed by electrical distribution companies on transmitted radiated switching voltage sources, ballasts, or other equipment.…”

DC micro grids have grown increasingly popular in the energy grid in recent years, as distributed generation has increased. Distributed generation refers to small or large-scale renewable energy that is linked to the main power system. Renewable energy sources like solar and wind power help the local grid, but their output is inherently intermittent and unpredictable, interfering with regular grid operation. Some of these issues can be mitigated by using energy storage in conjunction with renewable energy. Renewable energy is often linked to the grid using power electronic converters. The goal of this research is to simulate and evaluate transmitted emissions in the time and frequency planes using IEEE 1459 to investigate the impacts of DC / DC converters on DC lines, particularly for renewable energy generation. While there are standards and norms for frequencies up to 2 kHz and beginning at 150 kHz, the frequency range 2-150 kHz only has suggested techniques and propagation restrictions. As a result, the emission conveyed in the frequency range of 2-150 kHz is a subject that must be comprehended. The structure of the generation model, as well as the idea of power quality in electricity generating models, will be investigated using data collected through experimental and computer simulations on a medium-scale hybrid network connected to the grid. The technological advances acquired will subsequently be utilized to evaluate the power quality of various DC and AC single/three phase power systems (such as computer servers, airplanes, and so on).

“…With the growing urbanization in recent years, the rising number of buildings causes an increase in energy consumption [4]. In worldwide, energy used in buildings can be 45% -50% of total energy consumption in countries [5]. Especially in energy crises and environmental pollution, energy-saving and efficiency in buildings are essential [6].…”

Electrical energy is indispensable in our daily life with the developing technology. The most important feature is reliable and sustainable transmission of electrical energy to consumers is to provide the supply-demand balance in real-time. The ever-increasing demand for electrical energy, gradual depletion of traditional resources used to meet demand, and increasing dependence on foreign sources resulted in diverse electricity generation plants. As a result of this diversity, with the increase in the importance of electricity storage systems and awareness of energy-saving, Demand Side Management (DSM) gains great importance in ensuring supply-demand balance. DSM reduces costs by scheduling consumption instead of increasing generation to balance supply and demand. Residences constitute a large part of energy consumption worldwide, so DSM applications in buildings increase efficient usage of energy. Various management strategies can be used to save energy depending on the building type. In this article, an overview of Energy Management System (EMS) strategies to increase energy efficiency is presented. Then a case study is carried out in a residential model in Matlab/Simulink environment. The electrical devices were controlled with a Fuzzy Logic Controller (FLC), taking into account comfort, cost, and Demand Response (DR). In addition, Renewable Energy Resources (RES) to demonstrate their contribution were modelled and integrated into the system. Finally, case studies were conducted, and a comparative analysis of obtained results was carried out.
