Evaluation of Dynamic Stability of Microgrid Energy Storage System and Solar Power Plant

A microgrid is made up of electrical and thermal loads, distributed generation sources (DGs), and energy storage systems (ESS). The low inertia of the analogous system makes it difficult to control and run an autonomous microgrid without the assistance of the power grid. A small signal model of a microgrid, comprising a solar power plant and a battery energy storage system (BESS), has been simulated in the MATLAB simulator environment in order to look at the dynamic stability of the microgrid. In the system simulation section, the microgrid is put through a series of tests that include lowering the power of the solar power plant, managing the active and reactive power, compensating for imbalances, and Gridforming-Gridfollowing operations to synchronize with the grid. Microgrid control ensures that the microgrid operates correctly under a variety of tests in both states where it is connected to the power grid and when it is disconnected from it, based on the outputs.
