摘要：
In view of the influence of wind power uncertainty on additional cost of peak load regulation in new energy sending power grid under spot market trading mechanism，a dynamic optimization model of power grid price considering additional cost of peak load regulation is proposed，which provides flexible price signal for peak load regulation resources such as thermal power，energy storage and combined demand response of electricity and heat to participate in peak load regulation of power grid，ensures the accuracy of clearing price in spot market，and improves the ability of each power subject to absorb new energy and system carbon emission reduction. Firstly，based on the new energy transmission grid，the peak shaving demand method considering the uncertainty of wind power is studied，and the additional cost model of peak shaving resources such as thermal power，energy storage and combined demand response of electricity and heat is established. Secondly，the bidding strategy of each power subject in the spot market is studied. Considering the peak shaving additional cost trading mechanism，a spot market clearing model is established to minimize the operating cost，and the cooperative game algorithm is used to solve the model to calculate the clearing price of each subject of the new energy sending power grid. Finally，taking the actual operation data of a new energy sending power grid in Northeast China as an example，the simulation results show that the proposed dynamic optimization model of power grid price considering peak shaving additional cost can effectively improve the power grid’s ability to absorb new energy and ensure the efficient and stable operation of the power spot market. © 2023 Science Press.
