摘要
为平抑光伏功率波动,消纳弃光量,提出了一种基于光伏混合储能的配置策略研究。首先对光伏功率波动特性及弃光量进行分析,根据光伏功率波动特性确定并网目标控制域,提出平抑功率波动以超级电容为主、压缩空气储能为辅的配置策略。然后以压缩空气储能消纳弃光为主,基于冷热电三联供,提出一种针对三种不同情景能量分配的供给补偿模式。最后以新疆某光伏电站为例,进行算例分析,验证了该方案的可行性。
In order to suppress the fluctuation of photovoltaic power and utilize the abandoned sunlight resource,a configuration strategy based on photovoltaic hybrid energy storage is proposed.Firstly,the photovoltaic power fluctuation characteristics and the amount of abandoned sunlight resource are analyzed,and the grid-connected target control domain is determined based on the photovoltaic power fluctuation characteristics.A configuration strategy to suppress power fluctuations with super capacitors as the mainstay and compressed air energy storage as the auxiliary is proposed.Then,based on compressed air energy storage and the combined cold,heat and power system,a supply compensation model for energy distribution in three different scenarios is proposed.Finally,a photovoltaic power station in Xinjiang is taken as an example to carry out a case analysis to verify the feasibility of scheme.
