Electricity market decision-making double-layer clearing model considering grading electricity price

The invention discloses an electricity market decision-making double-layer clearing model considering grading electricity prices, and belongs to the technical field of electric power system control. The purpose of the invention is to adopt an in-province-inter-province double-layer market clearing decision model, and the overall optimal power market decision double-layer clearing model considering the grading electricity price can be realized between the upper layer and the lower layer of the double-layer model by transmitting decision variables. The method comprises the steps of upper-layer model construction, lower-layer model construction, model monolayer, nonlinear constraint linearization processing and objective function linearization processing. The double-layer market clearing model provided by the invention not only embodies the coupling of intra-province-inter-province transactions, but also integrates the price and ecological attributes of the electric quantity, so that the operation cost of the wh
