Abstract
One of the most critical issues in modern complex power systems is to reduce losses and improve system load through various methods such as compensating capacitors, electronic power equipment, installing distributed generation (DG) sources and changing the system configuration. Each of these methods has its own impact on the characteristics of the power system and should be considered simultaneously to conduct a comprehensive study close to the real situation. Installing DG units and changing the layout of the network are the most widely used methods of improving power system characteristics. Due to the importance of the problem, in this study, a new method for locating and determining the optimal capacity of DG units and optimal configuration of radial distribution systems simultaneously using the Jaya optimization algorithm is proposed to reduce losses and improve system loadability. Jaya optimization algorithm is one of the newest meta-heuristic algorithms that has a high ability to solve complex high-dimensional optimization problems. One of the advantages of this algorithm is having a simple structure with high search capability. The proposed method was tested on a 33-bus test system. Simulink and MATLAB software coding environment was used to program and implement the proposed method and the results of numerical studies showed that the proposed method is well able to find the network optimal configuration, optimal location and capacity of DG units, so that losses are minimized and system load capacity is improved.
