摘要
为了对含分布式电源的配电网进行规划,提出了考虑配网实际运行约束下以配电网网络损耗、电压偏移及DG投资运行成本为目标函数的多目标优化模型.采用基于Levy Flights的粒子群优化算法对所构造模型进行优化,并对33节点配网系统进行仿真.结果表明所建模型是合理的,改进的PSO算法对求解含DG的配电网多目标优化问题是有效可行的.
Considering the operation constraints of the distribution network, a multi-objective op- timal model is established by minimizing the loss of the distribution network, the voltage devia- tion and the DG investment operation costs. The PSO-LF algorithm is proposed to optimize the model. By using the update mechanism of Levy Flights, PSO-LF algorithm can improve the low efficiency of PSO algorithm and help jumping out of the local optimal particles. The simulation results of the 33 nodes distribution system show that the above-mentioned model is reasonable and the PSO-LF algorithm is feasible to solve the multi-objective optimization problems of the distribution network with DG.
