The invention discloses an electric quantity decomposition method and device. The method comprises the following steps: constructing a virtual thermal power plant based on a plurality of thermal powerplants; adding the virtual thermal power plant to a preset power plant set to obtain a target power plant set; according to the priority sequence of a plurality of contract types contained in a plurality of power plants in the target power plant set and the total contract electric quantity under each contract type in the plurality of contract types, determining the decomposition electric quantityunder each contract type corresponding to the plurality of power plants by taking the contract execution degree deviation for minimizing the power plant difference as a target; determining the decomposition electric quantity of the virtual thermal power plant corresponding to each contract type, and calculating the total decomposition electric quantity of the virtual thermal power plant; and decomposing the total decomposed electric quantity of the virtual thermal power plant to obtain the decomposed electric quantity of each thermal power plant under a plurality of corresponding contract types every day. According to the invention, the problem that the difference among power plants from various sources is difficult to consider under the condition of ensuring the economy when the power system is scheduled in the related technology is solved.
Description
technical field [0001] The present application relates to the technical field of power system dispatching operation, and in particular, relates to a method and device for power decomposition. Background technique [0002] With the rapid development of the electricity market and new energy power generation, the proportion of market-oriented electricity and new energy installed capacity in the power system is increasing, and the fairness and economy of the contract electricity decomposition results have an increasing impact on the system operation in the day-to-day , Unreasonable decomposition of electricity will lead to the risk that the electricity contract cannot be completed. How to optimize the decomposition of contract power in the largest range, give full play to the guiding role of the power market in the dispatching operation of the power grid, maintain the risk at an appropriate level at a reasonable cost, and reliably meet the needs of power market participants is t...
