Description

TECHNICAL FIELD

[0002] Electricity spot trading is the core link of electricity market reform, which is a market-oriented electricity trading form taking electricity commodity as the transaction object and short cycle as the transaction cycle. Its core is to form a price signal reflecting the real-time electricity supply and demand relationship through market competition. Market participants such as power generation enterprises, power selling companies and power users make declarations and matching in the spot market for the next day and shorter time electricity trading volume and price. Day-ahead trading determines the preliminary trading plan for the next day, and intraday and real-time trading adjusts according to the actual load, new energy output and other deviations. Finally, the real-time delivery of electricity is realized. This trading mode can accurately reflect the time and space value of electricity, guide the flexible adjustment of power generation side and the optimization of user side power consumption behavior, and promote the consumption of wind power, photovoltaic and other new energy, and encourage flexible resources such as energy storage and peak shaving units to participate.
