A Center of Mass Determination for the Optimum Placement and Deployment of the Renewable Energy Sources for Micogrids

The objective of this paper is to determine the location and the size of the renewable energy sources to be installed to a power system with a number of conventional generators. Since renewable energy sources (RESs) usually have fast dynamics and low inertia, conventional generators could encounter large disturbances in their productions. As the magnitudes of the disturbance exceed certain limits, instability could be induced in the operation of various generators. The impact of installing certain RES capacity at specific nodes on the stability and operation of the power system is proposed to be evaluated through developing a modified load flow analysis model to the microgrid system and analyzing the impact of the variation in RES production on the distributed generators. The proposed method automatically checks for the optimum placement of the RES to improve the stability of the system. The optimum placement point is referred to as the center of mass point for the microgrid system.
