Abstract With the development of new energy technology, more and more isolated power systems located in remote mountainous areas start to use both new energy generators and diesel generators as power supply. These power systems have the functional requirements for new energy inverters supplying power independently and diesel generators in parallel power supply. When supplying power independently, the new energy inverters run in voltage source control mode, while they run in current source control mode in parallel operation with diesel generators. Based on these features of the system, this paper proposes a control strategy combining inverter mode-switching and quasi-synchronization in parallel operation with diesel generators. The strategy solves the problem in the control of inverters and diesel generators parallel operation. It is verified through electromagnetic transient time-domain simulation and physical experiment on 1∶1 prototype.
