摘要/Abstract

摘要： 随着分布式电源的渗透率逐渐增大，其本身所具有的波动性和不确定性给配电网的电能质量及其稳定性带来了巨大挑战。考虑配电网在现有慢动作调节设备难以满足无功电压调节需求的情况下，将改善因光伏随机波动性所引发的电压偏差和波动作为优化目标，提出了一种考虑分布式光伏多运行状态调节能力与传统无功调节设备相协调的配电网多时间尺度无功电压协调控制方案。通过日前和分钟级多个时间尺度的配合，充分利用配电网中分布式光伏、电容器组和电抗器组，实现电压控制的目标。最后，以含分布式光伏的冀北某21节点实际配电系统为例进行仿真算例分析，验证了所提优化方法的有效性。

Abstract: As the penetration of Distributed Generators (DGs) grows larger, the fluctuation and uncertainty of DGs have posed great challenges to the power quality and stability of the distribution network. Considering that the existing slow-motion regulating equipment does not meet the requirements of reactive voltage regulation, a multi-time scale reactive voltage coordinated control scheme for distribution network is proposed. It is aimed to improve the voltage deviation and fluctuation caused by the random volatility of photovoltaic (PV) by considering the coordination regulation ability between the distributed photovoltaic multi-operation state and the traditional reactive power regulation equipment. The active power and reactive power of PV, capacitor operation and reactor operation are coordinated to achieve the goal both in day-ahead optimization and minutes’ optimization. Finally, the validity of the proposed method is verified by the simulations with a 21-node actual distribution system with distributed PVs in North Hebei grid.
