Power compensation in the microgrid by SMES using the current source inverters

In this paper, the authors proposed the loop microgrid system composed of loads, Superconducting Magnetic Energy Storage (SMES), and renewable energies such as solar and wind generators. The system adjusts the balance of supply and demand in the microgrid by compensating the power fluctuation of renewable energy sources with SMES. The SMES is connected with two independent Current Source Inverters (CSIs) in order to control power flow in the microgrid as well as at the interconnection with the main power system. The aim of this paper is to control power flow at the point of interconnection with the main system and the microgrid. The system was simulated by using PSIM and MATLAB/Simulink. The authors proved that the system can control the power flow as expected.
