基于分区协调控制的主动配电网电压支撑运行策略
摘要：考虑分布式电源(distributed generation，DG)、配电网静止同步补偿器主动参与调压，提出了一种基于分区协调控制的主动配电网电压支撑运行策略。首先，提出了DG电压支撑能力分布的概念。其次，基于电压支撑能力分布设计了一种具体的DG配置函数，并给出各调压设备的配置方案。然后，通过分析各设备的电压支撑能力，划分各设备的电压支撑域及联合支撑域，并提出了一种基于分区协调控制的电压支撑运行策略。最后，在IEEE BUS-33标准系统中验证了所提策略的有效性。结果表明，所提策略能充分利用DG电压支撑潜力，避免各调压设备动作冲突，保证无功补偿设备维持一定的容量备用，达到良好的调压效果。
Abstract:Based on the active participation of the distributed generation (DG) and distribution static synchronous compensator in voltage regulation, this paper proposes a voltage support strategy based on zone-division control in the active distribution network. First, the concept of DG voltage support capability distribution is proposed. Second, a specific DG configuration function is designed based on the distribution of voltage support capability, and the configuration scheme of each voltage regulating equipment is given. Then, by analyzing the voltage support capability of each piece of equipment, the voltage support region and joint support region of each piece of equipment is divided, and a voltage support operation strategy based on zone-division control is proposed. Finally, the effectiveness of the proposed method is verified in the IEEE BUS-33 case. The result shows that the proposed strategy can make full use of the potential of DG voltage support, avoid the conflicting actions of various voltage regulation equipment, ensure that the reactive power compensation equipment maintains a certain capacity reserve, and achieve a good voltage regulation effect.
