Quotation decision-making system and method of power generator in electric energy market and frequency modulation market

The invention relates to a quotation decision-making system and method for a power generator in an electric energy market and a frequency modulation market. The quotation decision-making system comprises a market information input module, a supply-demand ratio calculation module, a quotation scheme selection module, a market price prediction module, a unit data input module, a profit analysis module and a decision-making output module. And the profit analysis module calculates income, cost and profit of two market participating products, namely, the scheme of only participating in the electric energy market quotation and the scheme of participating in the electric energy market and the scheme of participating in the frequency modulation market quotation, and outputs a decision with higher profit by comparing the profit of the two schemes obtained by the profit analysis module. The method aims at maximizing the profit of the power producer, decisions are made on market participation mode selection, a quantitat
