What are the requirements for microgrid protection
Microgrids require control and protection systems. The design of both systems must consider the system topology, what generation and/or storage resources can be connected, and microgrid operational states (including grid-connected, islanded, and transitions between the two). Operating and. . Inverter controls can be grouped into three categories: grid-following (GFL), grid-forming (GFM), and grid-supporting. They need the grid voltage for operation. They are used to inject. . The protection requirement of these two types differs as the protection needs of an independent microgrid are intended for protecting components and systems within the microgrid, whereas a grid connected microgrid demands both internal and external protection. Part 2 of this series will be published in 2019, which will focus on several case studies and learnings from utility use cases. [pdf]
