Abstract: Aiming at distributed power generation and distribution network scheduling problem, a distributed predictive control algorithm is designed, and an active frequency distributed predictive control model of DG grid-connected operation system is established. In the forecasting control period, the Nash equilibrium control solution of the distributed power grid is obtained. Multi-distributed grid-connected power generation online optimization control, through the model predictive control system to achieve safe and stable operation of the grid. And finally, the accuracy of the conclusion is verified by simulation analysis. When the distributed power supply and distribution network are dismounted, the distributed predictive control method can realize the decentralized predictive control state, so that the distributed power supply can run stably, and after the next grid connection, the distribution network will not form a great impact, which is conducive to the stable operation of the distribution network.
