【摘要】：以投资费用最小和系统可用输电能力(available transfer capability,ATC)最大为目标,建立了多类型柔性交流输电系统(flexible AC transmission system,FACTS)的多目标优化模型,并考虑了多个约束条件。提出一种嵌套的多目标粒子群优化算法求解该多约束非线性N-P困难问题的Pareto解集,该算法的外层用于计算多目标优化问题,内层用于计算系统的可用输电能力和静态电压稳定指标。结果表明不考虑其他因素时,晶闸管控制串联电容器(thyristor controlled series capacitor,TCSC)是最合理的配置选择;当FACTS安装数量有限时,相比统一潮流控制器(unified power flow controller,UPFC)和静止同步补偿器(static synchronous compensator,STATCOM),多种FACTS设备混合安装可以在经济上和效果上取得较好的平衡;若电网在有限投资水平下需要较高的可用输电裕量,应首先考虑并联型和串联型FACTS混合安装的方案。在IEEE-14节点中对所提方法进行的验证表明该方法的正确性和有效性,该方法可以同时确定FACTS的安装类型、安装地点和补偿容量。
[Abstract]:The available transfer capability of the minimum cost and system (available transfer capability, ATC) as the goal, set up multiple types of flexible AC transmission system (flexible AC transmission system, FACTS) of the multi-objective optimization model considering multiple constraints. Proposed a Pareto multi-objective particle swarm optimization algorithm for nested the multi constrained nonlinear N-P problem solution set, the algorithm is used to calculate the outer layer for the multi-objective optimization problem, the available transfer capability calculation system and static voltage stability index. The results show that without considering other factors, thyristor controlled series capacitor (thyristor controlled series capacitor, TCSC) is configured to select the most reasonable; when the amount of FACTS is limited, compared to the unified power flow controller (unified power flow controller, UPFC) and static synchronous compensator (static synchronous com Pensator, STATCOM, FACTS) mixed a variety of equipment installation can achieve a good balance in the economy and efficiency; available transmission margin if the grid needs to be higher in the limited investment level, we should first consider the parallel and series hybrid FACTS installation program. To validate the proposed method in the IEEE-14 node that is correct the feasibility and effectiveness of the method, this method can also determine the type of the FACTS installation, installation location and compensation capacity.
