Research on the Scale of Multi-regional Networking to Improve the Interoperability Benefits of Power Systems

In 2022, power rationing will occur to different degrees in many parts of the country. The state requires that the advantages of large power grids be brought into play and that cross-provincial and inter-regional power cooperation be strengthened to enhance power security capacity. In this paper, taking large-scale grid A and grid B as examples, the stochastic production simulation of power system is adopted, to study the benefits of grid A and B power mutual assistance such as installation substitution, peak shaving, accident support, clean energy consumption, etc. The research method of network scale based on seasonal mutual benefit and installed substitution benefit is put forward to provide reference for future cross-regional and inter-provincial network project research.
