| Abstract: | Because of the high penetration rate of renewable energy, the stable operation of microgrid is seriously affected. The method of scenarios generation and reduction is applied to build and solve the model of renewable energy randomness. Based on the droop control theory, ITAE index is used to realize the fast judgment of microgrid stability. A strategy considering the randomness of renewable energy sources is proposed to coordinate the economy optimization and stability optimization of microgrid. Results of MATLAB/Simulink simulation verify the correctness and effectiveness of the proposed model and method. |
