摘　　要：电压源换流器型高压直流输电(Voltage Source Converter⁃High Voltage Direct Current,VSC⁃HVDC)的接入改变了传统电力系统的网架结构以及最优潮流模型,针对此问题,提出采用改进粒子群算法的VSC⁃HVDC潮流计算方法。阐述了VSC⁃HVDC的基本原理及控制方式,考虑系统网损多时段全局优化,建立了含VSC⁃HVDC的交直流混联系统动态最优潮流(Dynamic Optimal Power Flow,DOPF)模型。接着采用自适应权重和异步变化学习因子的改进粒子群算法对建立的DOPF模型进行求解。最后,通过对改进的IEEE 14节点算例进行测试,验证了模型和算法的有效性。The connection of voltage source converter⁃high voltage direct current(VSC⁃HVDC)changes the grid structure of the traditional power system and the optimal power flow model.A VSC⁃HVDC power flow calculation method using an improved particle swarm algorithm(PSO)was proposed.Firstly,the basic principles and operating characteristics of VSC⁃HVDC were explained.Then,considering the multi⁃period global optimization of the system network loss,a dynamic optimal power flow(DOPF)model of the AC/DC hybrid system with VSC⁃HVDC was established,which was solved by the improved PSO algorithm using adaptive weight and asynchronous changing learning factor.Finally,the DOPF test of the improved IEEE 14⁃node calculation example verifies the validity of the model and algorithm.
