摘要
提出一种考虑直接负荷控制(direct load control,DLC)空调轮控的配电网无功优化协调控制方法。首先,分析DLC空调轮控及启动电压特性,提出负荷聚合商(台区)接入点的启动电压约束条件;然后,建立考虑DLC空调轮控的配电网无功优化协调控制模型,它以受控空调的启停状态、不同台区的空调负荷削减量以及全网调压设备的控制方案为优化变量,建立负荷节点电压尽量合格、对空调用户舒适度影响最小、空调负荷削减量与计划削减量偏差最小、全网有功网损最小的多目标函数,并在常规无功优化约束条件上,引入空调临界启动电压约束条件。为了提高求解效率,还提出一种种群先后更新策略的改进并行协同进化算法,并求解所建模型。最后,通过广州某实际10 kV节点53配电网进行仿真分析,验证所提方法的有效性。
This paper presents a kind of optimization and coordination method for reactive power of the distribution network considering direct load control（DLC）air-conditioning cycle control.It firstly analyzes characteristics of DLC air-conditioning cycle control and startup voltage and presents constraint conditions for startup voltage of the access point of load aggregator（LA）.Then,it builds the optimization and coordination control model which takes start-stop states of the controlled airconditioning,air-conditioning load reduction in different areas and the control schemes of voltage regulating equipment of the whole network as optimization variables and establishes multi-objective functions of qualified load node voltage,the minimum effect on comfort level of air-conditioning users,the minimum deviation of load reduction and planned reduction and the minimum active power network loss of the whole network.Meanwhile,it introduces constraint condition for critical startup voltage on the basis of conventional constraint conditions for reactive power optimization.In order to improve solution efficiency,it also proposes a kind of improved parallel cooperative co-evolutionary differential evolution algorithm（IPCCDEA）and solves the model.Finally,it makes simulating analysis on an actual 10 kV53-nodes distribution network of Guangzhou and verifies effectiveness of the proposed method.
