Title
Power conditioning system with seamless mode transition for microgrid island operations
Abstract
This paper proposes a design of power conditioning system (PCS) and microgrid island operations which is based on the PCS. The microgrid can be islanded from a utility grid and can be connected to the grid seamlessly after phase detection and synchronization to the grid through a phase-locked loop and a slew-rate controlled synchronizer, respectively. There are three microgrid operations based on the PCS. The microgrid detects a grid failure and switches fast to an island in the protection mode. On the other hand, it changes the operation mode smoothly through a stabilization period in the auto-island mode. The microgrid can also be an island through matching the supply and load during connection to the grid in the zero-energy mode. The function and performance of the PCS were verified though simulations with the PSIM tool. The PCS detected the grid failure and islanded successfully within 1 ms. Moreover, there was no influence on the load through the seamless mode transition.
