Joint Operation Strategy of CSP Plants with Wind Farms in the Spot Market Regarding Winter Heating
In order to achieve carbon peaking and carbon neutrality goals,it is a general trend for renewable energy re-presented by wind power to participate in the power spot market.However,wind power is often at a disadvantage in the market due to its inherent variability and unpredictability.The coalition of wind farm and CSP(Concentrated Solar Power)power station can reduce real-time output deviations,which in turn reduces unbalanced costs.This paper focu-ses on offering a bidding strategy of coalition of wind farm and CSP power station in spot market.Firstly,we analyzed the mechanism of wind power-CSP power station joint participation in the spot market.On this basis,we proposed an optimization model which comprehensively considers electricity supply income,heating supply income and real-time balance cost.In addition,we proposed a profit-sharing mechanism based on cooperative game theory using Shapley value and we also analyzed the impact of heat storage capacity on the revenue of the coalition.The results of the case study shows that the proposed strategy can make full use of the flexibility of the CSP power station and significantly im-prove the profitability and reduce the loss of wind curtailment.
