READ MORENREL has been involved in the modeling, development, testing, and deployment of microgrids since 2001. A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode.

READ MOREThe operating modes of microgrids are known and defined as follows 104, 105: grid-connected, transited, or island, and reconnection modes, which allow a microgrid to increase the reliability of energy supplies by disconnecting from the grid in the case of network failure or reduced power quality. 106, 107 In the islanded (standalone) operating
READ MOREMicrogrids provide dynamic responsiveness unprecedented for an energy resource. Microgrids can create efficiencies in many ways. For instance, using cogeneration to serve balanced electric and thermal loads, microgrids can achieve generation efficiencies above 80 percent compared to around 30 to 50 percent for conventional generation.

Thirdly, an ADN is a distributed network that is able to ''control a combination of distributed energy resources (generators, loads and
READ MOREMicrogrids are decentralized and autonomous systems that generate, distribute, and manage power locally. They can be found on islands, as well as on the mainland. Especially islands understand the importance of a clean and reliable energy system, as they often hold a unique ecosystem. However, due to their remote location and scarce resources
