河北南网电力市场“1+7”规则体系：储能容量租赁、现货交易及辅助服务重点梳理

Core Viewpoint - The article discusses the release of the "1+7" rule system (V4.0 version) for the Hebei Southern Power Grid electricity market, detailing revisions in market structure, spot trading, capacity leasing, ancillary services, and settlement mechanisms [2]. Market Structure and Participant Access - The Hebei Southern Power Grid electricity market includes three main trading segments: energy trading, ancillary service trading, and capacity trading. Energy trading is further divided into medium-long term and spot trading, while ancillary services include frequency regulation, ramping, and backup services [2]. - The scope of market participants has been expanded to include new entities such as energy storage companies, virtual power plants, aggregators, and smart microgrids. Specific technical parameters have been set for participation, such as a minimum independent storage charging power of 10 MW for frequency regulation [3]. Spot Market Trading Mechanism - The spot market operates on a model where generation side reports quantity and pricing, while the user side only reports quantity. The goal is to minimize system generation costs through centralized optimization [4]. - Pricing mechanisms involve node electricity prices for the generation side and a unified settlement point price for the user side. New entities must submit operational discharge curves for day-ahead market participation [4]. Medium-Long Term and Capacity Leasing Trading - Medium-long term trading requires segmented time periods, forming 24-hour segmented electricity and pricing, categorized into segmented trading and curve trading [5]. - Capacity trading is managed under the medium-long term market, with independent storage companies as lessors and renewable energy companies as lessees. Lessees must meet specific charging and discharging power and duration requirements [5]. Ancillary Services Market Operation - Currently, the Hebei Southern Power Grid primarily conducts frequency regulation auxiliary services and plans to establish a backup market. The frequency regulation market is organized after determining the day-ahead generation unit combination, using centralized bidding and marginal clearing [6]. - New market participants must declare parameters such as adjustment rate and rated power, with restrictions on their share of total frequency regulation rate demand set at a factor of k, currently defined as 0.3 [6]. Retail and Settlement Management - The retail market adopts a package system, divided into public and private packages, with various pricing methods including market linkage, fixed prices, or profit-sharing [7]. - Settlement for spot trading participants generally follows a "daily clearing, monthly settlement" model, with green electricity trading separating energy and environmental value settlements [8].
