Evaluation of New Energy Consumption Capacity in Distribution Networks Considering DG Reactive Power Regulation and Uncertainty
In order to fully consider the impact of uncertainty and control diversity of distributed power generation on the operation of distribution networks,an evaluation method for the new energy consumption capacity of distribution networks considering reactive power regulation and uncertainty of distributed power generation was proposed.Firstly,the impact of distributed power generation on the voltage distribution of the distribution network,the reactive power regulation ability of distributed power generation,and the uncertainty model of distributed power generation output were analyzed;secondly,with the optimization objectives of maximizing the new energy consumption capacity and minimizing network losses,and taking into account the active reactive power regulation and uncertainty of distributed power generation as important constraints,an evaluation model for the new energy consumption capacity of the distribution network was established;then,using the output of distributed power generation and reactive power compensation devices as optimization variables,a fast non dominated sorting genetic algorithm was used to solve the problem,achieving accurate evaluation of new energy consumption capacity;finally,the verification was conducted through application examples.The results indicate that the proposed evaluation method achieves reliable evaluation of the new energy consumption capacity of distribution networks.
