摘要
Abstract
As distributed photovoltaic and electric vehicle charging piles become more widespread in distribution networks,the problem of reactive power optimization in distribution networks is becoming increasingly complex.The paper constructs an active distribution network reactive power optimization framework that integrates the grid connection of new energy and electric vehicle charging stations,with the goal of minimizing the operating costs of distribution networks and optimizing system stability.Stochastic models for photovoltaic generation and electric vehicle charging behaviors,as well as working state models for energy storage systems,have been developed to accurately reflect the uncertainty of distributed generation and loads.A multi-objective reactive power optimization mathematical model is designed,and the weight coefficient allocation method is used to comprehensively consider the economy and security of distribution networks.The dung beetle optimization algorithm is introduced to solve the model to improve the accuracy and speed of the solution.The results show that adjusting the power factor of charging piles reduces the use of reactive power compensation devices,shortens the operating time of capacitors and load tap-changing transformers,enhances the reliability of system control in distribution networks,and improves the resilience of distribution networks.关键词
