A Comprehensive Evaluation Method of Reactive Voltage Coordination Control Strategy in Active Distribution Network

摘要

In order to quantitatively compare different reactive voltage coordinated control strategies and improve the profitability of active distribution net-work investment, this paper has proposed an evaluation method of reactive voltage coordinated control strategy for active distribution network is proposed. Firstly, based on the macro criteria of economy, device performance, voltage quality and safety, a double-layer reactive voltage coordinated control strategy evaluation system with macro criteria layer and micro criteria layer is established. Secondly, combining subjective and objective factors, DEMATEL-ANP-Anti-entropy Weight method and improved grey relational degree analysis method are used to calculate the weight index of criterion layer and index layer respectively. Finally, through the analysis of three common reactive voltage coordination control strategies, the practicability and effectiveness of the evaluation method proposed in this paper are verified, which can provide decision support for the follow-up study of reactive voltage coordination control strategy in active distribution network.
