摘要考虑有功网损、节点电压稳定和线路电压稳定3个优化指标,将分布式电源选址和定容优化问题转化为多目标非线性规划问题。然后利用归一化-权重方法将多目标优化问题转换为单目标优化问题。采用粒子群（PSO）算法求解分布式电源的最优接入位置和接入容量。将所提的分布式电源最优选址和定容方法与已有的方法作对比分析,并通过IEEE 33节点算例验证本文所提方法的正确性和有效性。

Abstract：The locating and sizing of DGs (Distributed Generators) are studied and transformed into a multi-objective nonlinear planning problem by considering three indices: power losses, bus voltage stability and line voltage stability. Then the multi-objective optimization is reformulated as a single-objective optimization problem by means of normalized-weight theory. The PSO(Particle Swarm Optimization) algorithm is used to achieve the optimal locating and sizing of DG. Comparison is carried out between the presented method and the traditional method, and the case study on IEEE 33-bus system verifies the correctness and effectiveness of the new method.

Key words： distributed generation location and sizing voltage stability indices particle swarm optimization
