摘要
配电网分区间联络线的柔性化改造,使得潮流可以在不同分区间通过柔直线路快速转移。为直观展现配电系统在满足安全运行约束条件下的最大安全运行范围,文中提出一种基于JAYA算法的交直流柔性配电网稳态安全域求解方法。考虑VSC-HVDC稳态模型、交流系统潮流模型及其约束条件,以负荷供应值为目标函数,建立交直流柔性配电网稳态安全域模型。在Matlab仿真软件改进IEEE33节点系统中,采用JAYA算法对交直流柔性配电网安全边界点进行求解。另外,还针对VSC不同容量以及VSC-HVDC控制模式组合对稳态安全域的影响进行分析。仿真结果表明,相比于PSO和GA算法,JAYA算法收敛速度快、精度高。
With the flexible transformation of interzone contact lines in distribution network,the power flow can be transferred quickly through flexible and direct lines between different zones.In order to show the maximum security operating range of power distribution system under the constraints of security operating,a JAYA algorithm based steady-state security domain solution method for AC/DC flexible distribution network is proposed.In consideration of the steady-state model of VSCHVDC,the power flow model of AC system and their constraints,the steady-state security domain model of AC/DC flexible distribution network is established with the load supply value as the objective function.In the IEEE33 node system improved by Matlab simulation software,JAYA algorithm is used to solve the safety boundary points of AC/DC flexible distribution network.The impact of different VSC capacities and VSC-HVDC control mode combinations on the steady-state security domain are analyzed.The simulation results show that,compared with PSO and GA,JAYA algorithm has faster convergence speed and higher accuracy.
