Optimization configuration of photovoltaic and energy storage microgrid system in high way service areas based on energy self-sufficiency
摘要
Abstract
Building upon the demand for energy self-sufficiency of highways,particularly within weak grid networks,this study proposes an engineering-oriented dual-layer optimization algorithm model for scientific configuration of photovoltaic and energy storage systems for typical microgrids with multiple transformer areas in highway service zones.In the inner layer,an operational optimization scheduling model was established with the objective of minimizing energy consumption costs and reverse power flow to the grid.This model simulated the optimal annual scheduling of the system based on specific photovoltaic and energy storage capacity parameters and calculated indicators such as electricity purchase costs.It also accounted for safety constraints within multiple distribution systems.The outer layer integrated the annual electricity purchase costs with the investment and operational costs of the photovoltaic and energy storage system,aiming to minimize the annualized equivalent cost.It also considered installation capacity limitations to generate the optimal photovoltaic and energy storage capacity configuration scheme in service areas.The algorithm solving process was designed using an improved particle swarm optimization(PSO)algorithm and mixed-integer programming solver for solving constraint interger programs(SCIP)for efficient model solution.A case demonstrated that the proposed model could effectively achieve the optimal configuration of photovoltaic and energy storage capacity,resulting in an annual saving of 27.4%in electricity purchase costs.Moreover,the payback period for the photovoltaic storage system investment was 47.6%shorter than the planned operational lifespan,significantly reducing the overall system cost.关键词
