A remote synchronous control method of large-scale inductive loads in distributed generation (DG) systems is proposed. Firstly, a mathematical model with networked coupling effect is established, in which permanent magnet synchronous generator (PMSG) is regarded as a node of power generation and permanent magnet synchronous motor (PMSM) is considered as a practical inductive load. Then, numerical simulations were made to analyze characteristic of remote synchronization of large-scale inductive loads in DG systems with different topology network structures that including star network, multilayer networks, random network and actual power system of IEEE39. It shows unexpectedly that a practical inductive load, through relaying action of generator unit, implements remote synchronous controlling, which is important for stability of synchronization of DG systems.
