Abstract

The stochastic of photovoltaic power and demand variation in microgrids can cause dynamic changes of microgrid operation mode. To take this dynamic change into account in the design of inverter controller

a method for inverter controller optimization of parameter based on dynamic probabilistic eigenvalue analysis is proposed. This method uses characteristic root of dynamic probability distribution characteristics as a micro power grid stability evaluation index

taking the micro grid inverter controller parameters in the overall optimization with inequality constraint is represented as the nonlinear optimization problem and uses the evolution algorithm to solve the optimization problem. This method can take account for the influence of the varieties of the real time operation of microgrid on system stability accurately and comprehensively

the optimal control parameters of which has good robustness. Simulation results demonstrate the effectiveness of this method.
