Study on Metro Power Supply Load Model and Construction Idea of Virtual Power Plant

In this paper, the problem of subway power supply system participating in the construction of virtual power plant is studied, and the key problems in the process of virtual power plant construction of centralized power supply mode subway system are analyzed. The load model of subway power supply system is established through simulation analysis, and the experimental verification is carried out. The aggregation response ability of main loads of subway is analyzed, Based on the research results, the construction idea of virtual power plant for metro power supply system is put forward. The research results show that the subway power supply system has great advantages in regulation capacity and regulation capacity, and it is an important resource for the development of virtual power plant.
