Abstract :

Recently the use of AC transmission system (FACTS) devices and distributed generation resources as technology in power and distribution systems is increasing. This equipment affects various parameters such as voltage profile, line losses, short circuit current, stability, and reliability of the system, and therefore determining the optimal installation location, their number and size are one of the important issues that are considered because the installation of these devices and Resources in non-optimal locations increase system losses and negatively affect voltage profiles and other system parameters. In this paper, the simultaneous optimization of the number, location, and size of distributed generation resources and static synchronous compensation is used and in order to solve the optimization problem, a genetic algorithm (GA) is used. For this purpose, a multi-objective function including operating costs and generation of distributed generation resources and static synchronous compensation and system load capacity are presented and the simulation results were analyzed for two 33 and 69 IEEE standard networks. The results show that with increasing system load, the cost increases because the number of equipment related to distributed generation sources and static synchronous compensator increases. Also, the simultaneous optimization and placement of this equipment reduces costs and increases the load capacity of the distribution system.
