Abstract：With the increasing penetration of renewable energy grid,a sharply reduce of inertia of power system due to the replacing of synchronous generator is threatening the renewable energy power systems.For the purpose of enhancing the stability of power grid,this paper proposes a stability solution based on motor-generator pair(MGP) system.Firstly,the relationship between the active power and the motor parameters is analyzed by analyzing the phase relationship between MGP terminal voltage and the excitation potential,and then model the closed-loop source-grid phase control method which controlling active power transport by changing the voltage phase difference between the renewable source and power grid.Then,the operating pattern of MGP system is discussed,and a pattern which stabling MGP system is proposed,which enable the MGP system to transmit active power stably with source-grid phase control method.Finally,simulation and experimental verification of the feasibility of the control method of the present invention is proposed.
