Reactive Power Planning in Distribution Network by Photovoltaic System

In this research, the different modes of the 33-bus network were investigated with open DSS and MATLAB software. The simulation program was implemented using the colonial competition algorithm in two general sections. In the first case, loads were considered constant, and in the second case, they were probably modeled. Each of these states had sub-sections. In these sub-sections, location and measurement of photovoltaic sources were investigated. The specified objective functions were also explored separately to provide a comprehensive form of the proposed method. The results of the simulation with MATLAB with the help of open DSS indicated that by using the optimal location and measurement of the photovoltaic power plant, the system losses could be significantly reduced and the quality of the delivered power to the subscribers could be improved. By improving the voltage profile of the buses of the power system, subscribers would have a higher quality power. Finding the optimal size and place of the photovoltaic power plant using a multi-criteria objective function was investigated in this book.
