Problems solved by technology

[0004] As co-participants in the power market, the bidding strategies of the power generation side and the user side will affect the transaction situation of the power market, thereby affecting the allocation efficiency of power resources in the power market
At present, there are few studies on user-side electricity price forecasting. Existing user-side bidding strategies are usually based on users' predictions of short-term electricity prices, and the scientificity and accuracy cannot meet the requirements of users to participate in grid bidding.

Abstract

The invention relates to a bidding strategy for electricity purchase. The strategy comprises that a day similar to an electricity-price-to-predict day is selected via a grey correlation analysis method; according to the electricity price of the similar day, the electricity price of the electricity-price-to-predict day is predicted via a multivariate linear regression method; according to historical electricity prices of the similar days, the predicted electricity price of the similar day is obtained via the multivariate linear regression method, and a relative error probability density distribution function of electricity price prediction is established according to the historical and predicted electricity price; and according to the relative error probability density distribution function and the electricity cost of the electricity-price-to-predict day, bidding for electricity purchase is carried out via particle swarm optimization. According to embodiments of the invention, bidding for electricity purchase is carried out by utilizing the electricity cost of the day similar to the electricity-price-to-predict day, and the accuracy is high; and the established relative error probability density distribution function is used, and the electricity price of the electricity-price-to-predict day is adjusted via particle swarm optimization, so that the electricity purchasing price of the electricity-price-to-predict day is obtained, and bidding for electricity purchase of users is more accurate and more scientific.

Description

technical field [0001] The invention relates to the technical field of power market transactions, in particular to a bidding strategy for power purchases. Background technique [0002] The market is the most effective way to allocate resources, and electric energy, as a kind of power resource, has a high allocation efficiency in the electricity market environment. In the electricity market, the price is the core of the whole market. The fluctuation of electricity price directly affects the flow and distribution of electricity resources in the market. The electricity transaction through bidding has become a new model of my country's electricity industry. [0003] The bidding in the electric power industry includes the bidding on the power generation side and the bidding on the power consumption side. At present, the bidding in the electric power industry is mainly the bidding on the generating side. Bidding on the power generation side refers to the bidding of power plants t...
