摘　　要：对微电网中的分布式电源(DG)接入进行优化配置可以大大地提高微电网运行的可靠性和经济性。在考虑DG接入的相关性以及负荷重要性的基础上,建立了以考虑DG接入相关性并以微电网运行经济性最优为目标函数的多目标分层优化模型,并采用改进的粒子群算法(IPSO)进行求解。将优化模型及IPSO算法应用于一28节点微电网网架中,通过不同优化方案的对比证明了微电网中对DG接入进行优化配置的重要性,同时表明IPSO算法对于求解此类问题的可行性和有效性。Optimal allocation of distributed generation （DG） in micro grids can significantly improve the stability and benefit the economy of micro grid operation. Under consideration of relevance of DG access and load importance, a multi-objective model is established under consideration of DG access relevance, taking optimized economy of micro grid operation as its objective function, and the improved particle swarm optimization （ IPSO ） is used for the solution. The optimized model and IPSO are applied to a 28 - node micro-grid network structure. The comparison between different optimization schemes demonstrates the importance of optimal configuration of DG access in micro-grids. It is shown that the IPSO algorithm in this study is feasible and effective for solving such problems.
