摘要
传统黑启动主要由火电机组及水电机组承担,考虑在光伏资源丰富地区以光伏电站和储能系统联合承担黑启动任务,需要对光伏电站能否完成黑启动任务进行评估,并确定合适的储能配置。设计了光伏黑启动可行性评估方法,提出了基于光伏黑启动可行性评估的储能配置方案。首先,将待启动的黑启动负荷进行需求分析,提出光伏可行性评估指标,结合评估指标以及光伏出力分析,去除不良数据的同时进行光伏黑启动可行性评估;然后,将光伏场景进行划分,根据场景特点设计不同光储控制策略,并引入储能出力可行度概念,设计储能的配置方案;最后通过MATLAB仿真软件,验证了可行性评估的方法及所配储能提升光伏黑启动执行度的有效性,表明该方法可以有效提升光伏黑启动的可行性。
Traditional black start is mainly undertaken by thermal power units and hydropower units,photovoltaic power stations and energy storage systems are considered to jointly undertake the black start task in areas rich in photovoltaic resources.Therefore,it is necessary to evaluate whether photovoltaic power stations can complete the black start and determine the appropriate energy storage configuration.The feasibility assessment method of photovoltaic black start is designed,and the energy storage configuration scheme based on the feasibility assessment of photovoltaic black start is proposed.Firstly,the demand analysis of the black start load to be started is carried out,and the photovoltaic feasibility evaluation index is proposed.Combined with the evaluation index and photovoltaic output analysis,the photovoltaic black start feasibility evaluation is carried out while removing bad data.Then,the photovoltaic scenes are divided,different photovoltaic energy storage control strategies are designed according to the characteristics of the scenes,and the concept of energy storage output reliability is introduced to design the configuration scheme of energy storage.Finally,through MATLAB simulation software,the feasibility evaluation method and the effectiveness of energy storage to improve the implementation of photovoltaic black start are verified.The results show that the proposed method can effectively improve the feasibility of photovoltaic black start.
