Operation protection of microgrid

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). There is no guarantee that behavior of DERs will be common amongst device types or even amongst vendors. This complicates control philosophies and can lead to unintended and unmodelled instabilities in the. . 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. The first part of this chapter is. . This is a preview of subscription content, log in via an institution to check access.
