Optimal Method for Photovoltaic-storage-charging Capacity Configuration of Microgrid-in-chain on Expressways Considering Load Spatio-temporal Characteristics
摘要
Abstract
To solve the problem of charging electric vehicles on highways,a capacity configuration method for highway chain microgrid,"photovoltaic-storage-charging,"is proposed considering the spatiotemporal characteristics of loads.Firstly,using the"source-network-load-storage"model as the basic framework,we construct a chained microgrid structure for highways and explain its operation mode.Secondly,based on Monte Carlo simulation and queuing theory,we predict electric vehicles' charging load and queuing time at each service area node in the chain microgrid.Subsequently,a comprehensive cost function is proposed considering the construction and maintenance costs of the integrated facility of"optical-storage-charging"and the charging queue time costs of automotive users.Then,an optimization model to minimize the comprehensive cost is constructed.The optimal solution for the capacity configuration of"optical-storage-charging"is solved by using an adaptive particle swarm optimization algorithm.Finally,we take a section of a certain expressway as an example for numerical analysis.The results indicate that the method proposed in this article can solve the capacity configuration problem of"photovoltaic-storage-charging"in the chained microgrid of highways.关键词
