摘要
针对提高电网静态电压稳定性、输电能力、暂态稳定性等多个目标,设计灵活交流输电系统(flexible AC transmission systems,FACTS)装置优化配置的数学模型。在分析几种典型FACTS装置、静止无功补偿器(static var compensator,SVC)、静止同步补偿器(static synchronous compensator,STATCOM)和可控串联补偿器(thyristor controlled series compensator,TCSC)功能特性的基础上,结合不同FACTS装置的投资费用,给出求解单目标最优解的计算方法。提出一种利用智能帕雷托(smartPareto,sPareto)解的方法获取多目标函数帕雷托(Pareto)前沿最精简的表示形式,直接反映各配置方案之间的折衷,实现方案的优化选择。在新英格兰39节点系统上对所提出的方法进行仿真验证,结果证实了上述方法的有效性和经济性。
Aiming at improving static voltage stability, transfer capability and transient stability of power grid, mathematical model of optimal flexible AC transmission system （FACTS） devices placement was designed. Calculation method was given to get single objective optimal solutions considering investment cost based on the analysis of functional characteristics of several typical FACTS devices such as static var compensator （SVC）, static synchronous compensator （STATCOM） and thyristor controlled series compensator （TCSC）. A method was proposed to obtain a minimal representation of Pareto frontier of multi-objective function using smart Pareto filter. It can reflect the compromise of each scheme and help to make an optimal choice. Simulations were performed on New England 39-bus system, results testify the validity and economy of the proposed method.
