摘要为解决主动配电网中分布式可再生能源和储能系统造成的电压波动影响,基于模型预测控制理论提出了主动配电网电压调节控制策略,充分利用主动配电网中分布式电源、储能系统和有载调压变压器,实现采用最小控制成本的控制方案进行电压控制。该控制方案基于模型预测控制,采用多步滚动优化,使得电压控制过程更为灵活平滑,控制模型求解采用二次规划。通过IEEE 33节点辐射状配电网系统算例分析,证明了所提电压控制策略的可行性和有效性。

Abstract：In this paper,a model predictive control (MPC)-based voltage control strategy has been proposed to correct the voltage problems caused by renewable energy sources and storages in active distribution networks.The controller takes full use of distributed generations (DGs),storages,and on-load tap changers (OLTCs) to limit the voltages within the nominal operation region at the lowest cost.And a multi-step optimization is used to smooth the control process.This voltage control scheme leads to a quadratic programming problem which can be solved easily.Results obtained from simulation and comparative analysis on IEEE 33 node radial distribution network demonstrate the feasibility and effectiveness.

Key words： Active distribution network on-load tap changer (OLTC) model predictive control (MPC) voltage control quadratic programming
