| 摘 要： | 柔性多状态开关(flexible multi-state switch,FMS)是支撑新型电力系统背景下配电网运行控制能力提升和可再生能源接入渗透率改善的重要技术装备,针对现有配电网中FMS的规划并未详细考虑FMS与分布式电源(distributed generation,DG)的协调配置,以及对于FMS接入带来的可靠性提升考虑不足的问题。文章在规划配置阶段详细考虑了含FMS和DG的协同优化运行,并充分计及FMS接入带来的可靠性收益,构建了基于嵌套优化的FMS和DG选址定容双层优化配置模型。针对双层嵌套规划模型求解的复杂性,提出了基于改进粒子群算法和GAMS(general algebraic modeling language)算法相结合的模型求解策略,以改造后的IEEE 33节点算例系统为例,对所提出模型和方法的有效性进行了验证,结果表明提出的方法相比传统单一FMS规划具有更好的经济性,能最大程度地降低配电网年综合费用,同时减少用户因停电带来的损失。

| Abstract: | Flexible multi-state switch (FMS) has an important advantage in improving the operation control ability of distribution network and improving renewable energy access. The existing FMS planning methods in distribution network do not consider the coordinated configuration of FMS and distributed generation (DG) in detail, and the reliability improvement brought by FMS access is not considered. To this end, this paper considers the cooperative optimal operation of distribution network with FMS and DG in detail, fully takes into account the reliability benefits brought by FMS access, and constructs a two-level optimal configuration model based on nested optimization for sizing and siting of FMS and DG. Aiming at the complexity of solving two-level nested programming model, a model solving strategy based on the combination of improved particle swarm optimization and general algebraic modeling language (GAMS) is proposed. The effectiveness of the proposed model and method is verified on an improved IEEE 33-node example system. The results show that the proposed method has better economy than the traditional FMS planning method because it can reduce the annual comprehensive cost of distribution network to the greatest extent, and reduce the loss of users due to power failure. |
