A fuzzy control method and device for a micro-grid system

By combining fuzzy control methods and machine learning models with historical data from microgrid systems, a fuzzy control rule base is constructed to generate fuzzy input vectors and standard input vectors. This addresses the shortcomings of control strategies for microgrid systems in complex scenarios, enables flexible responses to renewable energy fluctuations and load changes, and improves the system's operating efficiency and stability.
