Optimal DG placement considering voltage stability enhancement using PSO

摘要

The increasing energy demands are stressing the generation and transmission capabilities of the power system. Distributed generation (DG), which generally located in distribution systems, has the ability to meet some of the growing energy demands. However, unplanned application of individual distributed generators might cause other technical problems. In this paper a DG placement method using Particle Swarm Optimization (PSO) based algorithm has been proposed to enhance the voltage stability margin and to reduce the real power losses of the system. Newton - Raphson power flow method Continuation Power Flow and Modal Analysis are used to identify the appropriate location for DG placement. To show the effectiveness of the proposed DG placement method, this approach is implemented in an IEEE-14 Bus System using PSAT which is a MATLAB toolbox environment.
