Coordinated Voltage Control for Active Distribution Network Considering the Impact of Energy Storage

In order to solve the problem of voltage violation in the distribution network caused by high penetration of renewable resources, an active-reactive coordinated optimization method considering the impact of energy storage is proposed. The problem of voltage deviation brought by renewable energy is analyzed, and it is verified that the problem of voltage deviation can be solved from both aspects of active power and reactive power.The coordinated optimization model is presented, with minimum total nodal voltage deviation as the objective function. In addition, the adaptive particle swarm optimization algorithm based on distributed entropy is presented to solve the mathematical problem. The validity and practicability of the proposed method is verified in case study. (C) 2019 The Authors. Published by Elsevier Ltd.
