READ MOREMicrogrids combine various distributed energy resources (DER) to form a whole system that is greater than its parts. However, regardless their size, fully grid-tied system with distributed generation (DG) that cannot operate in island mode are not microgrids, but instead can be defined as active distribution networks.
READ MOREThis article examines the trade space between the resilience and cost of an island microgrid. The article presents two models for the resilience and the cost of the microgrid. The resilience model considers the invulnerability and recoverability of the microgrid and represents the power balance of the microgrid, energy storage, and
READ MOREThe U.S. Department of Energy defines a microgrid as a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. 1 Microgrids can work in conjunction with more traditional large-scale power grids, known as macrogrids, which are anchored by major

READ MOREIn recent years, renewable microgrids have moved from a futuristic concept to executed projects. Although utilities have become comfortable with the status quo of the centralized model of production, falling costs of renewable energy technologies and the volatility of fossil fuel prices are opening the door for portions of the grid to return to their localized roots.
