摘要
集成应用分布式新能源、新型储能、柔性直流输配电等源网荷储技术装备,构建适用于高速公路长线型特点的绿色柔性供电系统,是交通用能低碳转型的重要路径。本文提出一种高速公路源网荷储一体化绿色供电系统规划方法,考虑交通负荷可扩展性和新能源出力随机性,通过全生命周期仿真模拟和边际效益分析对系统容量进行最优化配置。某典型高速服务区算例表明,所提方法兼顾规划准确性与计算可行性,实现交通动态增长的用能需求与随机波动的新能源供应之间的最优匹配,有效提升投资净收益。
A green and flexible power system integrating distributed renewable energies(RE),battery energy storage(BES),voltage source converter based direct current(VSC-DC)transmission,et al facilitates the green-oriented transition of transportation.Considering the expansibility of transportation load and the variability of RE generations,an optimal capacity allocation algorithm is proposed for the source-network-load-storage integrated highway power system based on full-life-cycle chronological operation simulation and marginal utility analysis.Case studies on a typical highway service area verify that the proposed method outperforms in both planning accuracy and economical optimality.The optimal match between the dynamically growing traffic load and the stochastic RE generations is achieved and an improved net investment income is obtained.
