摘要/Abstract

摘要：

在“双碳”背景下，可再生能源发电在电网中的比重越来越高，电力系统的AGC调频、备用等辅助服务需求也显著增加。储能电池系统作为一种新型灵活资源，在提供辅助服务方面潜力巨大。同时，储能电池系统也面临着参与电能量市场与辅助服务市场的收益权衡问题。为此，本文以锂电池储能电池系统为例，基于机会成本概念，提出了储能电池系统提供AGC调频的机会成本分析与建模方法；进而提出了储能电池系统参与电能量市场与AGC调频市场运行策略。算例分析表明，储能电池系统提供AGC调频的边际机会成本随申报容量的增加而增加，因此，当AGC调频容量的边际机会成本与AGC调节成本之和等于AGC调频补偿价格时，储能电池系统的总收益达到最大。

Abstract:

In the context of "Double Carbon," the penetration of renewable energy generation in the electricity grid is increasing. It advocates for increased AGC frequency control and reserve services requirements. As a newly emerging flexible resource, energy storage has great potential to provide ancillary services. Simultaneously, it faces a trade-off issue between the energy and ancillary service markets. In this context, an opportunity cost analysis approach for lithium battery energy storage in delivering AGC service is provided. An effective capacity allocation mechanism for energy storage between the energy and AGC markets is provided. Case studies reveal that the marginal opportunity cost of AGC capacity for energy storage increase with the growth of the declared AGC capacity. As a result, the return from energy storage is maximized when the marginal opportunity cost of AGC capacity equals the compensation price for AGC frequency control.

Key words: lithium battery energy storage, AGC frequency regulation, opportunity cost, energy market, market strategy
