Research on Trading Mechanism and Safety Checking Mechanism of Trans-provincial Peak-Shaving Auxiliary Service

There are differences in resource distribution and power consumption among provinces in the regional power grid. To carry out trans-provincial peak-shaving auxiliary service market transactions can realize the cross-provincial mutual benefit of peak-shaving resources, thereby enhancing the capacity of regional power grid to absorb renewable energy. Based on the above concepts, aiming at the problem of insufficient peak-shaving resources in the provincial power grids, this paper puts forward the trading mechanism and security checking mechanism of trans-provincial peak-shaving auxiliary service. A market clearing pricing model for peak-shaving auxiliary service in low-load periods is constructed to motivate relevant units to provide peak-shaving auxiliary service with clear price signals. A simplified model of a regional power grid is simulated and analyzed. The results show that the trading mechanism and safety checking mechanism proposed in this paper are feasible and effective.
