![]() ![]() This microgrid class is connected to and can island from the distribution grid.Įxamples of this classification of microgrids in New Jersey includes several DER systems that serve a campus setting such as a college or university, healthcare/hospital campus, pharmaceutical complex or military base. This classification includes either a single or multiple DER systems connecting multiple buildings, but controlled by one meter at the point of common coupling. Level 2 or single customer / campus setting also referred to as the partial feeder microgrid. ![]() This microgrid class is connected to and can island from the distribution grid.Įxamples of this classification of microgrids in New Jersey are a single owner PV system with either a backup generator or an off-grid inverter that can isolate from the grid, or a CHP that serves just a single building load such as a hospital, office building, restaurant, school or multifamily public housing building. ![]() This is a single DER system such as a photovoltaic solar (PV) system, combined heat and power (CHP) or fuel cell (FC) system that is serving one customer through a single meter. Below is one classification of microgrids based on interconnection to the grid. A microgrid can be categorized in several different manners. Currently, there is no definitive or universally accepted classification system for the different types of microgrid configurations. The above definition for microgrids covers a broad array of systems, technologies, customer types and interconnection types. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode. The United State Department of Energy (USDOE) Microgrid Exchange Group in 2012 developed a generally accepted definition of a microgrid asĪ microgrid is a group of interconnected loads and distributed energy resources (DER) within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. ![]()
