Power flow control in AC loop microgrid with a SMES connected with two independent converters

In this paper, the authors proposed a new circuit topology of AC loop microgrid with a Superconducting Magnetic Energy Storage (SMES) and solar and wind generators. The SMES is connected with two converters controlled independently to supply power to different parts of the microgrid. The balance of supply and demand in the microgrid is adjusted by controlling the converters. The aim of this study is to control power flow between the main power system and the microgrid so as to reduce reverse power flow. The authors proved that SMES can control the power flow in the proposed microgrid through the numerical simulation by use of PSIM and MATLAB/Simulink.
