考虑低碳政策的储能容量价值分析
摘要：在“双碳”目标的背景下，大力发展以风光为代表的新能源，构建适应新能源大规模发展的新型电力系统已成为我国能源转型的必然路径。然而，在电力负荷高峰时期，新能源往往处于较低的出力水平，难以对系统提供可靠的支撑，而储能具有双向快速灵活调节能力，能够为系统提供电量、容量和安全支撑服务，但储能是容量有限型资源，所以准确评估储能对于系统充裕性的贡献变得越来越重要。为此，文中概述储能容量价值评估框架，基于等可靠容量比例概念，提出一种考虑边际值的可信容量定义表征储能的容量价值，给出储能可信容量的具体计算方法；建立考虑碳交易市场和可再生能源配额制的电源规划模型进行市场模拟，分析引入不同低碳政策对储能可信容量的影响。算例结果表明，储能可信容量在不同程度上受到碳交易市场和可再生能源配额制的影响。
Abstract:Under the background of realizing the goal of “double carbon”, vigorously developing new energy represented by wind and solar and building a new power system that adapts to the large-scale development of new energy have become the inevitable path of China’s energy transformation. However, in the peak period of power load, new energy has lower active power, it is difficult to provide reliable support for the system. Energy storage has the ability of two-way fast and flexible adjustment, and can provide power, capacity and security support services for the system. However, energy storage is a resource with limited capacity, so it is becoming more and more important to accurately evaluate the contribution of energy storage to system adequacy. Therefore, this paper outlined the assessment framework of energy storage capacity value, and based on the concept of equal reliable capacity ratio, a capacity credit definition considering marginal value was proposed to characterize the capacity value of energy storage, and a specific calculation method for capacity credit of energy storage was given. The power planning model considering the carbon trading market and the renewable energy quota system was established for market simulation, and the impact of the introduction of different low-carbon policies on the capacity credit of energy storage was analyzed. The calculation example shows that the capacity credit of energy storage is affected by the carbon trading market and the renewable energy quota system to varying degrees.
