基于多目标优化的新型配电网储能选址与容量配置策略研究OA

In allusion to the problem of voltage limit violation in the new distribution network due to the access of wide-area distributed power sources,under the goals of both enhancing the absorption capacity of new energy and optimizing economy,a strategy for energy storage site selection and capacity configuration considering multiple factors is proposed.A new distribution network model is established,and node voltage stability and dynamic thermal rating are introduced as indicators to evaluate the stability of the lines.A corresponding economic model is constructed,and the improved multi-objective particle swarm optimization algorithm is used to solve it.The effect of this strategy is verified by means of the IEEE 33-node model.The experimental results show that,in comparison with the traditional static thermal rating,the dynamic thermal rating introduced in the stability indicators can more accurately identify the lines prone to overload in the distribution network.Moreover,the installation cost of the energy storage system can be reduced by 47.37%by means of the improved particle swarm optimization algorithm.This strategy can not only better suppress the voltage fluctuation problem of the distribution network and improve the stability of the distribution network,but also effectively reduce the operating cost of the distribution network.
