Abstract

The use of renewable energy in recent years growing continuously. Power generation from renewable sources of energy is in the form of Distributed Generation (DGs). Intermittent DG renewable energy source is connected to the system of a microgrid. Problems found in the microgrid are power losses and voltage drop. Power losses and voltage drop will affect the quality of the electrical power distribution. In this paper, the application of a genetic algorithm is proposed for optimal placement of intermittent DG renewable energy source and capacitor bank for power losses reduction and voltage profile improvement in microgrids. Optimal placement of the DGs and capacitor bank in microgrid significantly reduces active and reactive power losses. Optimal placement of DGs also significantly improve voltage profile. Optimal Placement of Intermittent DG on the IEEE 69 Bus system using the GA method can reduce active power losses by 69.14 percent, while using the PSO method can only reduce active power losses by 69.09 percent.
