| Popis: | To deal with the deviations of frequency of microgrid system composed of multiple micro sources caused by load disturbance, the load frequency control of islanded microgrid system is studied based on linear quadratic differential games theory in this paper. Considering the operating characteristics of each micro source, different objective function weighting matrix is selected, and the control strategy of non-cooperative feedback Nash equilibrium of each micro source in microgrid system is researched. The simulation results show that the control strategy can accomplish system control targets, make full use of the various of characteristics of each micro source and balance the benefit of them. At the same time, the control strategy has good robustness to external disturbance and parameter variation of the internal unit. |
