Research on Modeling of Microgrid Load Frequency Control Based on V2G Technology

The vehicle to grid (V2G) technology of electric vehicles brings a new direction to the load frequency control (LFC) of the microgrid. The research and development of microgrid technology can improve and accelerate the large-scale integration of distributed power and renewable energy into the grid system, and it is a key technology from traditional grid to smart grid. Through the “source-load” characteristics of electric vehicles, the feasibility of V2G technology participating in microgrid load frequency is analyzed. The working principle of diesel generator set (classic micro-grid generator system) and electric vehicle is described, and a general and accurate dynamic mathematical model of micro-grid load frequency control based on V2G technology is established. The established model provides a basis for the design and research of control strategies and algorithms for microgrid LFC problems based on V2G technology, and provides a theoretical basis for the development of microgrid technology and smart grid modeling.
