Core Viewpoint - The article discusses the implementation of a series of rules for the electricity market in Hunan Province, focusing on long-term trading, spot market trading, and ancillary services, aiming to enhance market efficiency and participation [1]. Participation Entities - In the long-term electricity market, participants include energy storage companies, aggregators, virtual power plants, and smart microgrids [2]. - The spot market involves independent new energy storage and virtual power plants [2]. - The frequency regulation ancillary services market includes coal-fired, thermal storage, and gas units, as well as independent storage and virtual power plants [2]. Participation Content - Long-term market prices are formed within a range of "time-based trading benchmark price + upward and downward fluctuations," encouraging active peak-shaving participation [3]. - In the spot market, independent new energy storage must be no less than 5MW/10MWh and can participate by choosing to report volume without quoting prices, using the average node price for settlement [3]. - Virtual power plants also participate in a similar manner, using the unified settlement point price for their respective periods [3]. Frequency Regulation Market Details - The response time for coal, thermal storage, and gas units is set at 60 seconds, while hydropower units have a response time of 20 seconds, and storage units have a response time of 5 seconds [5]. - Independent storage must have a frequency regulation capacity of no less than 10MW, with a duration of at least 1 hour [5]. - The price declaration range for frequency regulation is set between 4-15 yuan/MW, with a clearing capacity cap of 10MW for frequency regulation units [5]. Market Parameters - Key market parameters include weight coefficients for regulation rate, response time, and regulation accuracy, with initial values set at 0.4, 0.3, and 0.3 respectively [6]. - The comprehensive frequency regulation performance index entry threshold is set at 0.3, with a standard response time of 60 seconds [6]. Market Connection - During the operation of the spot market, no separate peak-shaving ancillary service trading will be conducted within the province [9]. - The frequency regulation ancillary services market and the spot market will clear separately, with independent new energy storage required to choose participation in either market [9]. Peak-Shaving Ancillary Services Market - The price cap for the peak-shaving ancillary services market is set at no more than 450 yuan/MWh, aligning with the on-grid price of the province's grid-connected renewable energy projects [10]. - Specific price limits for coal-fired peak-shaving are set at 400 yuan/MWh for the fourth tier and 450 yuan/MWh for the fifth tier, while new energy storage is capped at 450 yuan/MWh [10].
