Quotation strategy optimization method of thermal power generating unit in electric power spot market

The invention relates to a quotation strategy optimization method for a thermal power generating unit in an electric power spot market, and the method comprises the following steps: S1, carrying out spot market clearing simulation according to spot market load prediction and other information and market generator unit quotation; s2, according to spot market clearing results in different scenes, target unit profit is calculated, and expectation of the target unit profit is calculated; and S3, according to the framework of the simulated annealing algorithm, by taking the maximum profit of the target unit as the target, adjusting the unit quotation strategy, and repeating the steps S1-S2 until the simulated annealing algorithm is finished. According to the method, the quotation strategy of the thermal power generating unit in the electric power spot market is optimized, so that loss of power generation enterprises caused by quotation errors is avoided, meanwhile, the quotation rationality of the power generation
