Problems solved by technology

In order to maintain the stability of the market and the reliability of the system operation, the power market managers will punish the power generators participating in the bidding of the power market when their output deviates. Due to the randomness and uncertainty of wind power output, wind power is Faced with market risks when participating in market bidding, which affects the income of wind power companies

Embodiment Construction

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the examples of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] The embodiment of the present invention provides a wind-fire joint bidding method that takes into account the penalty of wind power bidding deviation, specifically, such as figure 1 As shown, the hot-fire joint bidding method includes:

[0038] Step 1: Obtain the raw data required for market clearing before the day before, including the fuel cost function of the thermal power units of each power generator, the upper and lower limits of t...

Abstract

The invention discloses a wind-fire combined bidding method considering the penalty of wind power bidding deviation, which comprises the following steps: the original data required for market clearingbefore the day of bidding is obtained; According to the original data, the objective function and constraint conditions of maximizing social welfare are determined for the system unified marginal clearing model; the objective function of the maximum profit of wind-thermal power generation company is established; Particle Swarm Optimization (PSO) is used to calculate the clearing quantity and clearing price of social welfare maximization objective function which meets the constraint conditions, and then the objective function of the maximum profit of wind-fire combined power generation companyis solved, and the optimal wind-fire combined bidding scheme is obtained. According to the optimal wind-fire combined bidding scheme, the bidding is carried out in the electricity market. This methodcan be used to guide the bidding behavior of wind power suppliers in the electricity market and improve the profits of wind power suppliers.

Description

technical field [0001] The present invention relates to the electricity market, and in particular, to a wind-fire joint bidding method which takes into account the penalty of wind power bidding deviation. Background technique [0002] In 2015, Document No. 9 was officially issued, in order to build a "fair, open, orderly and competitive" power market system, marking the beginning of a new round of power market reform in my country. At the same time, in recent years, global environmental issues and energy issues Increasingly prominent, renewable energy has received extensive attention at home and abroad and developed rapidly. Due to the high construction cost and intermittent characteristics, wind power generation is not as economical and technical as traditional thermal power units, so it is currently unable to participate in the power market independently. Countries support its development by formulating subsidy mechanisms and policies. In the existing power market, power ma...
