兼顾新能源消纳和主动支撑电网能力提升的多类型储能容量优化配置

Optimal Capacity Configuration Method for Multi-type Energy Storage Systems Enhancing New Energy Consumption and Actively Supporting the Grid

在“双碳”发展目标下,新能源侧的储能需求已从“促进消纳”提升至“促进消纳+主动支撑电网”。面向此技术背景,提出了兼顾新能源消纳和主动支撑电网能力提升的多类型储能容量优化配置方法,并通过引入典型工况特征曲线提取方法优化了复杂模型的求解过程,最后基于典型新能源电站的历史数据测算了“促进消纳”和“促进消纳+主动支撑”场景下的储能配置需求及经济性,对比结果表明相较于“促进消纳”,“促进消纳+主动支撑”场景从技术上更能满足新能源侧的储能需求,且具有更好的经济性。

Under the dual-carbon development target,the demand for energy storage on the new energy side has been raised from“promoting consumption”to“promoting consumption+actively supporting the grid.”In view of this technical background,this study proposes an optimal configuration method for a multitype energy-storage capacity to enhance the ability of new energy consumption and actively support the grid.A method for extracting the characteristic curves of typical working conditions was introduced to optimize the solving process of the complex model.In addition,based on the historical data of typical new energy power plants,the energy storage configuration requirements and economy under the three scenarios of“active support,”“promoting consumption,”and“promoting consumption+active support”were calculated.The results show that the scenario of“promoting consumption+active support”can technically meet the energy storage demand of the new energy side better,and it improves the economy.
