To minimize line losses of distribution systems, it is crucially important to define the size and location of distributed generators to be placed. This paper proposes a modified particle swarm optimization (MPSO) algorithm for distributed generation (DG) planning in a distribution system. MPSO is utilized to solve the proposed distributed generation (DG) planning model, and combined with penalty function, the DG planning problem is transferred into a problem to solve extreme-value without constraints, thus the calculation accuracy and global convergence ability of MPSO are effectively improved. Simulation of the proposed algorithm by 69-bus distribution test system and 33?bus distribution test system is conducted. Simulation results validate the correctness and adaptability of the proposed DG planning model and MPSO algorithm.
