Samimi O., Sadaat A., Kurvonboev B.I. , Abdumavlonov A.A., Xusanov J.X.

During last two-three decade the interest to Microgrid is increasing because of its advantages over conventional utility grids. Microgrid is a smart way to use renewable resources to generate electricity because it has advantages over traditional utility grids. Even though microgrid has some benefits, it must work with a lot of constant power loads that have negative incremental impedance and make the system very unstable. In this paper, the Microgrid consisting of the filter (RLC), converter P&O algorithm, and PID controller have been designed to meet the needs of the system with utility grid.
