政策解读 | 明晰规则、凝聚共识，构建电力辅助服务市场新生态

Core Viewpoint - The article emphasizes the importance of establishing a new ecosystem for the electricity ancillary services market in China, driven by the increasing share of renewable energy and the need for enhanced system flexibility and stability [2][4]. Summary by Sections Development Stages of Ancillary Services Market - The development of China's electricity ancillary services market can be categorized into three stages: 1. Vertical Integration Stage (before 2002) where ancillary services were bundled with generation and compensated through a unified electricity price [3]. 2. "Separation of Generation and Grid" Phase (2002-2006) where compensation for ancillary services was introduced based on cost recovery principles [3]. 3. Market Exploration Stage (post-2006) where the need for market mechanisms to enhance resource allocation became evident, leading to the launch of the first regional peak-shaving service market in 2014 [3]. Key Developments and Regulations - The issuance of the "Basic Rules for Electricity Ancillary Services Market" marks a significant step in China's electricity market reform, transitioning from an energy market to a multi-dimensional market that includes ancillary services [4][6]. Framework and Mechanisms - The article outlines several key aspects of the new rules: 1. Establishment of a clear framework for the ancillary services market [5]. 2. Definition of ancillary service types and their functions [6]. 3. Development of a compensation mechanism that clarifies who provides, benefits, and bears costs for ancillary services [5][8].

Encouragement of New Participants - The new rules encourage the participation of innovative entities such as energy storage companies and virtual power plants, recognizing their potential to enhance system flexibility [8]. Process and Workflow - A comprehensive workflow for market construction is established, covering all aspects from planning to implementation, ensuring a systematic approach to market development [8].
