Study on Frequency Stability of Two-Region Microgrid in Isolated Island Mode

Frequency stability of micro grid is very important for load and safe operation of system. In this paper, a method to control frequency stability of micro grid is proposed. By analyzing the generation characteristic and load characteristic of the generating unit, the mathematical model is deduced. The mathematical model of two-region micro-grid is constructed. By using the active disturbance suppression strategy to analyze the regional mathematical model, the effectiveness of the strategy is finally proved in the simulation software.
