Microgrids have been proposed as a way of integrating large numbers of distributed renewable energy sources with distribution systems. One problem with microgrid implementation is designing a proper protection scheme. It has been shown that traditional protection schemes will not work successfully. In this paper a protection scheme using digital relays with a communication network is proposed for...
The integration of distributed generation transforms current distribution networks from vertically operated to horizontally operated. This transition leads to problems related to protection coordination. In the future, new protection philosophies should be applied which guarantee the increase of the during-fault distributed generation availability. The paper presents a cost-effective protection scheme...
