Contract electric quantity decomposition method and device and medium

Abstract

The invention discloses a contract electric quantity decomposition method and device and a medium thereof, relates to the technical field of electrical engineering, and is used for reasonably decomposing contract electric quantity. In order to solve the problem that great risks are caused to the operation of the electricity market due to the deviation between the contract electricity consumption and the actual electricity consumption at present, the invention provides the contract electricity quantity decomposition method, which comprises the following steps of: through a power grid, calculating the purchase cost and selling price of the contract electricity quantity provided for non-market users; according to the method, a power market operation risk coefficient representing risks generated after contract execution in a day-ahead market environment is obtained, and then the power market operation risk coefficient is taken as a target function to perform contract electric quantity decomposition, so that the contract electric quantity obtained through decomposition can ensure that the power market operation risk is at a relatively low level to the greatest extent; the power market transition can be carried out stably and orderly, and the operation stability of the power market is further improved.

Description

technical field [0001] The present application relates to the technical field of electrical engineering, and in particular, to a contract electricity decomposition method, device and medium thereof. Background technique [0002] With the development of the electricity trading market, the stability of the electricity market operation has always been an issue that people pay attention to. In the current electricity market, there is a non-market user who purchases electricity by signing a contract in advance and then providing electricity from the grid of the guaranteed power supplier. [0003] In this way, there will be a problem. When non-market users sign contracts, the power settlement department cannot fully and accurately predict the electricity consumption and electricity consumption behavior of non-market users based on the existing load forecasting model and spot market price forecasting model. Furthermore, there is bound to be a discrepancy between the actual electri...

Problems solved by technology

[0003] In this way, there will be a problem. When non-market users sign contracts, the power settlement department cannot completely and accurately predict the electricity consumption and electricity consumption behavior of non-market users based on the existing load forecasting model and spot market price forecasting model. Furthermore, there must be a deviation between the actual electricity consumption of non-market users and the contracted electricity consumption in the pre-signed contract. At this time, the power grid needs to purchase electricity from the spot market and settle with non-market users according to the previously approved catalog electricity price.

Due to the different electricity prices in different trading hours, delivery of contracted electricity to non-market users when electricity prices are high and market electricity to market users when electricity prices are low may cause power grids and other power settlement departments to fail to achieve balance of payments, thereby affecting the electricity market. operation poses a great risk

[0004] Therefore, those skilled in the art urgently need a method for decomposing contract power to solve the current problem of great risk to the operation of the power market due to the deviation between contract power consumption and actual power consumption.
