A microgrid is a localized group of electricity sources and loads that can operate independently or in conjunction with the traditional power grid. It typically includes renewable energy sources, storage systems, and controllable loads. The CERTS Microgrid Laboratory Test Bed in MATLAB is a simulation platform designed to model and analyze the behavior of microgrids. Utilizing MATLAB software, the test bed enables researchers and engineers to study various aspects of microgrid operation, including control strategies, integration of renewable energy sources, grid stability, and resilience to disturbances. It serves as a valuable tool for developing and testing innovative technologies and strategies aimed at optimizing microgrid performance and enhancing the reliability and efficiency of decentralized power systems.
