高速公路微网的储能容量配置与调度优化策略
Energy storage capacity configuration and scheduling optimization strategy for the expressway microgrids
摘要
Abstract
To improve the utilization of clean energy for highways and achieve the scientific and economical allocation and flexible scheduling optimization of energy storage facilities,an energy storage capacity allocation and scheduling optimization model for highway photovoltaic-storage-charging microgrids is proposed.A novel solution algorithm was used to solve the model and conduct simulation analysis.Based on meteorological information along the highways and load conditions of highway service areas,a mathematical model for the highway photovoltaic-storage-charging microgrids was established.Monte Carlo simulations were conducted to analyze the charging loads of electric vehicles in the service areas.Additionally,based on the load characteristics of highway service areas,management centers,toll stations,and tunnels,a highway microgrid load model was developed.From the perspective of the economic efficiency of highway microgrids,a bi-level optimization model was established to achieve integrated optimization of energy storage system allocation and scheduling.The(Exponential Distribution Optimizer-Mixed-Integer Linear Programming,EDO-MILP)algorithm was applied to solve the model.Taking the distributed photovoltaic-storage demonstration project on the Panzhihua-Dali Expressway(Sichuan section)as an example,simulation and optimization were conducted over a period of 8 760 h.The simulation results showed that for microgrids with a photovoltaic installed capacity of 2 MW and a maximum load of approximately 800 kW,the introduction of 1 131 kW·h/283 kW of energy storage devices led to an annual increase in system revenue of 384 000 yuan,effectively improving the economic efficiency.This was a 42.8%improvement compared to the non-energy storage scheme and a 4.3%improvement over the empirical scheme.Additionally,the allocation scheme increased the microgrid system's consumption capacity for photovoltaic green electricity.Compared to the non-energy storage scheme,the consumption capacity increased by 5.7%,and compared to the traditional scheme,it improved by 3.4%.关键词
