Multi-time scale generation right transaction method for promoting wind power consumption

Abstract

The invention provides a multi-time scale generation right transaction method for promoting wind power consumption. The method comprises the following steps of 1, based on a long-term forward contract and day-ahead wind power forecast, performing day-ahead generation right transaction, determining a day-ahead generation right of each generation company, and locking the start-up and shut-down state of a large-scale thermal power generating unit; 2, based on a day-ahead generation right transaction result and a wind power forecast result updated 4h ago, performing 4h-ago generation right transaction, determining a generation right of each generation company, and adjusting the start-up and shut-down state of a rapid start and stop unit; and 3, based on a 4h-ago generation right transaction result and a 1h-ago wind power forecast result, performing 1h-ago generation right transaction and determining a final generation right of each generation company and the operation mode of an electric power system. The invention can promote the wind power consumption, improve the income of a wind power plant, and reduce the system production cost and risks of load losing or wind power abandoning during operation of an electric power system.

Description

【Technical field】 [0001] The invention belongs to the field of power systems, and relates to a multi-time-scale power generation right transaction method for promoting wind power consumption. 【Background technique】 [0002] The right to generate electricity refers to the right of the power generation company to generate electricity and sell electricity to the grid or users. In the regulated power system, it corresponds to the manufacturer's power generation quota obtained under a specific dispatch mechanism; while in the free competitive power market, it refers to the manufacturer's winning bid in the electric energy market in advance (such as the forward market, the day-ahead market). Correspondingly, the transaction of power generation rights refers to the sale and purchase of the above-mentioned quotas or winning bids. [0003] The transaction of power generation rights is essentially a process of rescheduling the power system and reconfiguring power generation resources...

Problems solved by technology

This "day-ahead plan + real-time adjustment" wind power consumption strategy does not make full use of wind power forecast information at different time scales; since the power generation resources available for adjustment in the power system are very limited on a real-time time scale, this will Restricting the adjustment of power generation, causing the system to lose load due to insufficient actual wind power or abandoning part of the wind power due to excessive actual wind power

[0007] In summary, the existing power generation rights trading methods do not fully utilize their own potential in the reconfiguration of power generation resources, especially in the flexible adjustment of system operation; at the same time, the existing wind power consumption system cannot make full use of wind power forecasting at different time scales information, it is necessary to combine the forecast results of wind power power, design the trading method of power generation rights, flexibly adjust the system operation mode, and promote the consumption of wind power power
