Electric power frequency modulation market transaction clearing and settlement method, device and system

Abstract

The invention discloses an electric power frequency modulation market transaction clearing and settlement method, device and system, and the method comprises the steps of optimizing a frequency modulation auxiliary service, electric energy and a standby auxiliary service based on the frequency modulation information, frequency modulation capacity demands and frequency modulation mileage demands declared by all market main bodies, and obtaining a day-ahead frequency modulation plan; clearing the frequency modulation auxiliary service to obtain a rolling frequency modulation plan based on the day-ahead frequency modulation plan and the frequency modulation information of rolling updating of the market main body participating in frequency modulation in the day-ahead frequency modulation plan;clearing the electric energy and the standby auxiliary service, and clearing the frequency modulation auxiliary service to obtain a real-time frequency modulation plan according to the real-time market demand and the frequency modulation information of rolling updating of the market main body participating in frequency modulation in the rolling frequency modulation plan; and settling frequency modulation income based on the real-time frequency modulation plan. Rolling frequency modulation is introduced so that the scheduling mechanism is enabled to properly adjust the day-ahead frequency modulation plan, the rolling frequency modulation plan can be generated, the real-time frequency modulation plan can be acquired based on the rolling frequency modulation plan, and safety and stability ofthe power grid can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of frequency regulation auxiliary services in the electric power market, and in particular relates to a transaction clearing and settlement method, device and system in the electric power frequency regulation market. Background technique [0002] With the rapid advancement of the new round of electricity reform, the construction of frequency modulation auxiliary services has become a top priority. The planned compensation mechanism under the "Two Detailed Rules" can no longer meet the development requirements of the power market. It is urgent to establish a market-oriented transaction mechanism for ancillary services and a user-side sharing mechanism, and actively guide and encourage power generation companies and power users to participate in the ancillary service market. [0003] With the rapid development of new energy sources such as centralized wind power and photovoltaics, major changes have taken plac...

AI Technical Summary

Problems solved by technology

The high proportion of new energy connected to the grid will inevitably squeeze the power generation space of traditional units, and its volatility, intermittent and difficult to accurately predict the characteristics of the power grid will greatly increase the demand for frequency regulation. If only relying on thermal power frequency regulation, not only cannot meet the grid frequency regulation demand, will also increase its own cost

The current compensation model and intensity of ancillary service plans have been difficult to meet the actual operation needs of the power grid, and it is necessary to use market-oriented means to solve the problem of insufficient frequency regulation capacity and adjustment means of the power system
