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.
