摘要：With a large quantity of distributed generators (DGs) integrated, the operation and control of distribution networks is faced with great challenges. Voltage regulation is a vital issue for active distribution networks (ADNs). Optimal placement for energy storage system (ESS) units is determined to enhance their impacts on voltage regulation by solving a mixed integer linear programming model. A voltage regulation strategy is proposed by coordinating DGs, ESS units and on-load tap changer (OLTC). The ADN is partitioned into various zones by using the sensitivity information. For each zone, ESS units play a very active role in voltage regulation coordinating with DGs. The OLTC is activated to ensure achieving the voltage regulation goal when DGs and ESS units are out of control scope. Simulation results on a 33-bus test system demonstrate the effectiveness and good performance of the proposed regulation strategy. © 2017 IEEE.
