Research on Collaborative Optimization Model of Park-level Integrated Energy System Participating in Power Peak Shaving

Due to the imbalance of source-load distribution and the randomness of the output of new energy in China, the peaking pressure of power grid is increasing. And the trouble of energy development is becoming more and more prominent. Under this background, it is proposed that to participate in power grid peak-shaving by optimizing the output of units in the multi-energy complementary park. The demand for peak-adjustable auxiliary service of power grid is the target of market regulation of peak-adjustment auxiliary service. How to maximize its own interests by participating in the power grid peaking under the current power market environment. This paper proposes an optimization model of comprehensive consideration of the demand of internal load and peaking of the park. And the feasibility and accuracy of the method are verified by the actual case.
