Market clearing method for bidding demand side market subject and generator set on same platform

Abstract

The invention discloses a market clearing method for bidding a demand side market subject and a generator set on the same platform. The clearing method comprises the following specific steps: step 1, solving a security constraint unit commitment problem considering demand-side quotation; step 2, solving a security constraint economic dispatching problem considering demand side quotation; step 3, calculating the node electricity price considering the demand side quotation; step 4, performing security check, and if the security check succeeds, executing step 6, if the security check fails, executing step 5; step 5, modifying a system operation boundary condition and a unit operation constraint condition, and turning to the step 1; step 6, correcting a load prediction curve of a corresponding bus node based on a demand side bid winning result, and carrying out second clearing on a power generation side to obtain a unit combination problem only considering the quotation of the power generation unit; step 7, solving an economic dispatching problem which only considers the quotation of the generator set; and step 8, calculating the node electricity price which only considers the quotation of the generator set.

Description

technical field [0001] The invention relates to the field of electric power spot market mechanism, in particular to a market clearing method in which demand-side market entities and generator sets bid on the same platform. Background technique [0002] Power users have considerable adjustment potential and need effective market mechanisms to guide their utilization. With the continuous improvement of the power spot market mechanism and the gradual liberalization of the user-side market, it has become the development trend of the power market to replace the traditional power demand-side management with demand-side response transactions, and the integration of demand-side resources into spot market transactions has far-reaching development. prospect. At present, my country's spot market adopts the participation method of quoting quantity but not quoting on the demand side at this stage, and guides the elasticity of user demand through clearing prices in the day-ahead market. ...

AI Technical Summary

Problems solved by technology

[0004] The invention discloses a market clearing method in which demand-side market entities and generator sets bid on the same platform, which helps to solve the problems of large peak-to-valley difference and severe load fluctuation of the power grid, and can realize separate pricing of the demand side and the generator set, Without affecting the interests of market players, the initiative of demand-side players in the market and enthusiasm for participating in the market can be improved as much as possible, and it can avoid demand response bidding behavior from affecting market prices, which is conducive to stabilizing the normal operation order of the spot market
