Energy storage systems can provide robustness to a microgrid installation by improving resiliency of the electrical supply and creating an ROI for the stakeholders
Microgrids continue to gain popularity in the built environment due to improved power reliability and quality, increasing system energy efficiency, resiliency from grid anomalies and financial benefits. Energy storage systems play an integral part of most microgrids. An energy storage system combined with a solar array or wind turbine managed by a specialized control system form the most common arrangement of a renewable microgrid.
The Department of Energy defines the 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. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island mode.”
