摘要/Abstract

摘要：

储能发展尚处于早期阶段，国内外均针对储能制定了一系列政策支持储能发展。相比于国内，欧洲、美国、澳大利亚等国家及地区储能相关政策及商业模式更成熟，储能项目经济性也更好，成熟的市场规则和良好的经济性更有利于储能行业健康可持续发展。对比国内外储能相关政策及商业模式，分析中国储能发展的不足，对国内储能发展具有重要的借鉴意义。本文首先介绍了欧洲、美国和澳大利亚在电价、规划、财税补贴、市场规则等方面的相关支持政策，分析了主要国家的表前和表后储能的商业模式；其次，总结了中国在储能规划、参与电力市场、补贴、强制配储能、电价等方面出台的相关政策，分析了新能源配储、用户侧储能、火储联合调频、独立储能等场景的商业模式；最后，通过对比国内外储能政策与商业模式，得出对我国储能政策及市场机制方面的启示，提出我国应在加大储能财税补贴力度、减少强配储能、加快储能参与电力现货市场进度、增加储能可参与的电力市场服务种类等方面进行改进和优化。

Abstract:

The development of energy storage technologies is still in its early stages, and a series of policies have been formulated in China and abroad to support energy storage development. Compared to China, developed countries such as Europe, the United States, and Australia have more mature policies and business models related to energy storage. Furthermore, their energy storage projects have better economic efficiency. Mature market rules and good economic performance are more conducive to the healthy and sustainable development of the energy storage industry. Comparing energy storage policies and business models of China and foreign countries, and analyzing the energy storage development shortcomings in China, has essential reference significance for developing the energy storage industry in China. This article first introduces the relevant support policies in electricity prices, planning, financial and tax subsidies, market rules, etc., in Europe, the United States, and Australia, and analyzes the pre-meter and post-meter energy storage business models in major countries. Secondly, this article summarizes the relevant policies introduced by China in energy storage planning, participation in the electricity market, financial and tax subsidies, mandatory new energy storage, and electricity prices. Moreover, it analyzes the business models of new energy distribution and storage, user-side energy storage, controlling frequency of thermal energy storage, independent energy storage, and other scenarios. Finally, inspiration is drawn for China's energy storage policies and market mechanisms by comparing energy storage policies and business models of China and foreign countries. It is proposed that China should improve and optimize its energy storage policies by increasing financial and tax subsidies, reducing the forced energy storage allocation, accelerating the progress of energy storage contribution to the electricity spot market, and increasing the types of electricity market services in which energy storage can participate.

Key words: new energy storage, policies, business models

英国电力市场服务类型"

服务种类	市场/服务	描述
频率响应服务	固定频率响应(FFR)	对频率变化的动态或静态响应，月度招标。有两个FFR类型：①动态：是一种持续提供的服务，用于管理系统的逐秒变动；②静态：通常是在定义的频率偏差下触发的离散服务
	静态低频	为了减少无法预测月度计划的资产的进入壁垒，静态低频(LFS)是FFR每周拍卖中可用的两种服务类型之一
	动态低-高频	为了减少无法预测月度计划的资产的进入壁垒。动态低-高频(DLH)是FFR每周拍卖中可用的两种服务类型之一
	动态遏制	动态遏制(DC)是一种快速作用的故障后服务，在发生故障时将频率控制在±0.5 Hz的法定范围内，只有当频率超出操作限制(±0.2 Hz)时才会激活。有两种不同的服务可以独立提供：①动态遏制低频；②动态遏制高频
	动态调节	动态调节(DR)是一种故障前服务，旨在缓慢纠正连续但较小的频率偏差。其目的是在50 Hz的目标附近持续调节频率
	动态稳定	动态稳定(DM)是一种故障前服务，旨在快速提供服务，目的是将频率保持在操作限制范围内，有助于通过快速响应来管理突然出现的大规模失衡
备用服务	快速备用	快速备用通过增加发电输出或减少需求消耗，提供快速可靠的有功功率输送
	慢速备用	慢速备用是一种故障后服务，旨在提供不同的正备用和负备用，并支持ESO在15分钟内将频率恢复到±0.2 Hz的义务。有两种不同的服务可以独立提供：①负慢速备用；②正慢速备用
	短暂备用	短暂备用是一种快速备用产品，旨在弥补动态遏制、动态调节和动态稳定的新频率响应服务与较慢备用产品之间的调节服务
	短期运行备用	当输电网络需求大于预测时，短期运行备用向ESO提供额外的电力(发电或减少需求的有功电力)
	需求增加	需求增加服务鼓励大型能源用户和发电商在可再生能源产量高、国家需求低时增加需求或减少发电。这种情况通常发生在夏季的夜间和周末下午
	超级最小输出功率	超级最小输出功率通过降低同步发电机的最低发电水平，直接降低与系统同步的发电机的最低功率输出水平或最小稳定输出功率之和
	平衡装置启动服务	平衡装置启动服务是国家电网在平衡机制中接入发电的一种机制，该装置不计划运行(参与者通常当天不可用)。该服务包含两个要素：①平衡装置启动将平衡装置单元带到可以在平衡机制时间范围内同步的状态；②热备用是指将平衡装置单元保持在这种准备同步的状态
	替代备用	替代备用是参与的欧洲输电系统运营商之间的一项协调服务，用于提供有功功率的增加和减少
无功功率服务	强制性无功功率服务	强制性无功功率服务(ORPS)提供变化的无功功率输出。在任何给定的输出处，可以指示发电机产生或吸收无功功率，以帮助管理靠近其连接点的系统电压。《电网规范》要求涵盖的所有发电机都必须具备提供无功功率的能力
系统安全服务	联跳闸	联跳闸服务是一种自动控制，在系统故障事件发生后，发电量可能会减少或断开。这项服务可以作为一种必要连接条件，也可以根据商业安排提供
	黑启动	黑启动是指在国家输电系统全部或部分关闭的情况下恢复电力的服务
	最大发电量	最大发电量需要在系统承压期间提供额外的短期发电输出，以实现系统平衡。此服务允许访问发电机正常运行范围之外的未使用容量
容量市场	容量市场	容量市场是一种通过可靠的容量来源来确保电力供应安全的服务
电力批发市场	日前和日内交易	日前和日内批发市场交易是从其他市场方出售和购买电力
