| 摘 要： | 针对大规模分散式光伏接入所导致的配电网节点电压越限以及光伏弃光问题,建立了具有计及可平移负荷的主动配电网的日前调度模型。分析了光伏弃光现象与电压及功率潮流之间的关系,构建光伏能源消纳的数学模型,并且针对不同类型可平移负荷的运行特点,分析了可平移负荷的调度特性。综合考虑静止无功补偿器对配电网的无功调度及节点电压的影响,将分布式光伏的消纳最大化问题等效为了一个混合整数规划模型进行求解。仿真验证其模型的有效性。

| Abstract: | Large scale photovoltaic grid connection will lead to the voltage over the limit of node-voltage in distribution network.In view of the problem of photovoltaic discarding caused by the voltage limit,an optimization model for coordinated scheduling is established in this paper.The function of this model is to minimize the light weight of photovoltaic,and to optimize the target by means of a variety of measures including the SL,the coordinated photovoltaic power and the static var compensator.Because the power flow equation in the model is nonconvex and nonlinear,a two order cone relaxation of the load flow equation is used to transform the model into a convex optimization problem.Modeling is carried out by considering the different conditions of the duration of the removable load.Taking a typical distribution network in Jinzhai County as an example,three photovoltaic degradation scenarios are simulated and compared. |
