摘　　要：为提高主动配电网电压分区控制能力,设计基于调度优先级的主动配电网电压分区控制方法.构建主动配电网电压分区控制参数约束模型,以静态极限电流、静态极限功角等参数为控制自变量,通过静态主动配电网电压态稳定性特征分布,拟合控制主动配电网线路阻抗与系统的静态参数.结合调度优先级控制策略,分析主动配电网电压分区参数融合模型,采用交流电网相对强度特征分析方法,完成主动配电网电压分区调度和优先级控制,实现主动配电网电压分区控制优化设计.仿真实验结果表明,所提主动配电网电压分区控制方法的输出稳定性较好,电网静态稳定性参数融合性较强,提高了主动配电网电压分区控制的鲁棒性.In order to improve the voltage partition control ability of active distribution network,an active distribution network voltage partition control system based on dispatching priority is designed.The voltage partition control parameter constraint model of active distribution network is constructed,and the static limit current,static limit work Angle and other parameters are taken as control independent variables.Through the characteristic distribution of voltage state stability of static active distribution network,the line impedance and the static parameters of the system are fitted to control the active distribution network.Combined with the dispatching priority control strategy,the voltage partition parameter fusion model of active distribution network is analyzed,and the relative strength characteristic analysis method of AC power network is adopted to complete the voltage partition dispatching and priority control of active distribution network,so as to realize the optimal design of voltage partition control of active distribution network.The simulation results show that the proposed method has better output stability and better static stability parameter fusion,which improves the robustness of active distribution network voltage partition control.
