中国电科院专家解读《电力辅助服务市场基本规则》

Core Viewpoint - The construction of the auxiliary service market in China's power system is essential for maintaining safety and stability, especially with the increasing share of renewable energy sources like wind and solar power, which poses new challenges to the power system [2][4]. Summary by Sections Development Stages of Auxiliary Service Market - The development of China's auxiliary service market can be categorized into three stages: 1. Vertical integration phase before 2002, where auxiliary services were bundled with generation and compensated through a unified electricity price [3]. 2. "Separation of generation and grid" phase starting in 2002, introducing compensation for auxiliary services based on cost and reasonable returns [3]. 3. Market exploration phase, initiated in 2014 with the launch of the first regional power peak-shaving service market, aimed at incentivizing participation in auxiliary services through market mechanisms [3][4]. Key Features of the New Rules - The newly introduced "Basic Rules for the Power Auxiliary Service Market" marks a significant shift towards a multi-dimensional market that includes auxiliary services alongside energy markets, providing a crucial institutional guarantee for the new power system [4][5]. - The core ideas of the rules include establishing a clear market framework, defining auxiliary service types, and creating a compensation mechanism that benefits both users and generators [5]. Main Content of the Rules - The rules encompass objectives, principles, member composition, service types, cost sharing, market connections, regulatory assessments, and risk prevention, aiming to standardize the auxiliary service market across the country [6][7]. - The rules consist of 12 chapters and 67 articles, detailing the overall requirements and operational guidelines for the auxiliary service market [6]. Implementation Goals and Pathways - The rules aim to support the participation of new operational entities such as energy storage, virtual power plants, and distributed energy sources in the auxiliary service market, while clarifying market establishment principles and transaction processes [7][8]. - The rules address key challenges in the current auxiliary service market, providing a framework for unified and standardized market construction across regions [8][9]. Cost Transmission Mechanism - The rules clarify the composition and calculation of auxiliary service costs, establishing a reasonable cost framework and principles for compensation based on the "who provides, who benefits" approach [9]. - They also outline the cost-sharing mechanism for users and generators, ensuring that the costs are fairly distributed among all parties involved [9].
