摘要
根据贵州农村山区的光伏发电项目将面临越来越多绿电消纳和电力现货市场交易竞争的问题,提出配备储能和充电桩的光储充一体化系统解决方案;基于储能电池价格和度电价格等因素,对光伏-储能-充电的项目进行经济敏感性分析;选取内部收益率为评价指标,分析电池价格和度电价格对项目内部收益率的影响,对于解决目前光伏电力现货市场交易竞争,提升项目经济性具有重要意义,为贵州因地制宜的发展光伏-储能-充电项目提供参考依据。
In response to the increasing challenges of green electricity consumption and competition in the spot market trading for photovoltaic power generation projects in rural mountainous areas of Guizhou,this study proposes an integrated photovoltaic-energy storage-charging system solution that incorporates energy storage and charging piles to address the issue of green electricity consumption.An economic sensitivity analysis is conducted for the photovoltaicenergy storage-charging project,considering factors such as energy storage battery prices and electricity prices per kilowatt-hour.The internal rate of return is selected as the evaluation metric to analyze the impact of battery prices and electricity prices on the project's internal rate of return.This analysis is crucial for addressing the current competition in photovoltaic spot market trading and enhancing the project's economic viability.The study provides a reference for the development of photovoltaic-energy storage-charging projects tailored to local conditions in Guizhou.
