摘要 在风电场内优化配置储能资源,可有效平抑风电强随机性与波动性对电力系统造成的负面影响,促进电网友好型风电场建设。目前,风电场储能系统存在应用功能单一、设备利用率低、盈利能力差等问题,制约了风电场储能系统的大规模应用。为此,该文对一次调频、功率预测补偿与新能源消纳等多种储能应用功能,提出一种风电场的多功能电-氢混合储能系统容量优化配置方法。首先,提出考虑一次调频、功率预测补偿与新能源消纳3种功能的风电场储能系统运行策略,进而提出了考虑储能设备特性的电—氢混合储能的能量管理策略;其次,在此基础上,基于时序生产模拟的方法,以净收益最大化为目标建立风电场多功能混合储能系统优化配置模型;最后,通过对河北省某风电场混合储能系统优化配置进行实例计算与分析。研究结果表明:采用该策略下的容量配置方法,能在考虑储能设备特性的基础上,满足电力系统多时间尺度的需求,有效提高电力系统的经济性。 Optimizing the allocation of energy storage resources within wind farms can effectively mitigate the negative impacts of wind power induced strong randomness and volatility on the power system,promoting the construction of grid-friendly wind farms.Currently,wind farm energy storage systems face issues such as single application functions,low equipment utilization rates,and poor profitability,which constrain the large-scale application of energy storage systems in wind farms.To address these issues,this paper proposes a method for optimizing the capacity allocation of a multifunctional electrical-hydrogen hybrid energy storage system in wind farms,incorporating various energy storage application functions such as primary frequency regulation,power prediction compensation,and renewable energy absorption.Firstly,an operational strategy for the wind farm energy storage system is proposed,considering the three functions of primary frequency regulation,power prediction compensation,and renewable energy absorption.Furthermore,an energy management strategy for the electrical-hydrogen hybrid energy storage system,taking into account the characteristics of the energy storage equipment,is proposed.Secondly,based on this,a wind farm multifunctional hybrid energy storage system optimization allocation model is established with the goal of maximizing net revenue,using a time-series production simulation method.Finally,a case study is conducted on the optimization and allocation of a hybrid energy storage system in a wind farm in Hebei province.The research results show that the capacity allocation method under this strategy,which considers the characteristics of energy storage equipment,can meet the multi-time scale demands of the power system and effectively improve the economy of the power system.
