摘　　要：当分布式电源和电动汽车同时接入配电网时,会对电网的经济运行产生一定的影响。为了让配电网运行更为经济化,研究分布式电源的最优发电功率和电动汽车的最优充电功率,使得网络损耗最小。因此,本文以接入分布式电源和电动汽车前后网损的变化量最大为目标函数。考虑每个节点均接入分布式电源和电动汽车,在给定功率约束下,利用模拟退火粒子群算法,计算出了最优的充电与发电功率。以20节点的网络为例,计算确定最优分布式电源的发电功率和电动汽车的充电功率,并且同时满足了网络损耗变化量最大的条件。When distributed power and electric vehicles are connected to the distribution network simultaneously,there is an impact on the economical operation of the grid.In order to avoid this and minimize power losses,the way to optimize the output power of distributed power along with the charging power of electric vehicles has been studied.This article,therefore,takes the maximum loss variation of the distribution network before and after its access to distributed power and electric vehicles as the objective function.Making sure that each node is connected to distributed power and electric vehicles under a given power,the optimal output power along with the optimal charging power are calculated in the following part of this article with an application of Simulated Annealing Based Particle Sward Optimization（SA-PSO）.It is considered to take the 20-node network as an example in which the optimal distributed power generation and the optimal charging power of electric vehicles are calculated while the power loss variation reaches its maximum.
