摘要:
“双碳”目标下城市公交车全面推进电动化,公交光伏充电站面临并网点负载压力大、运营成本高的问题。提出公交光伏充电站储能优化配置方法。基于大量的调研数据分析公交充电负荷特性,构建公交光伏充电站典型运行场景;综合考虑充电站运营商利益、公共交通通勤需求以及并网点的容量限制,构建计及全生命周期成本的公交光伏充电站电池储能优化配置双层模型。以北京某在营公交充电站为算例,验证了所提配置方法的有效性,量化评估了光伏发电余量上网、公交车充电策略、电网电价及电池购置价格等因素对充电站配置储能运营经济性的影响。

Abstract:
The electrification is fully promoted in urban bus under the “dual-carbon” goal, and public transportation photovoltaic charging station faces the problems of high load pressure at the grid-connection point and high operating cost. An optimal allocation method of energy storage for public transportation photovoltaic charging station is proposed. The charging load characteristics of public transportation are analyzed based on a large amount of research data, and a typical operation scenario of public transportation photovoltaic charging station is constructed. Comprehensively considering the interest of charging station operators, public transportation commuting demand and capacity limitation of grid-connection point, a bi-layer battery energy storage optimal allocation model for public transportation photovoltaic charging station is constructed taking into account the whole life cycle cost. Taking an in-service public transportation charging station in Beijing as an example, the validity of the proposed allocation method is verified, and the impact of photovoltaic residual feed-in, public transportation charging strategy, grid electricity price, and battery purchase price on the operating economy of charging station allocated with energy storage is quantitatively evaluated.
Key words:  public transportation photovoltaic charging station  energy storage allocation  commuter demand  distribution capacity  economy
