Resumen:
This paper proposes the use of superconducting magnetic energy storage (SMES) in combination with a distribution static synchronous compensator (DSTATCOM) as an effective controller of tie-line power flow of microgrids incorporating wind generation. The high penetration of wind generation causes fluctuations of tie-line power flow and significantly affects power system operations. This can lead to severe problems, such as system frequency oscillations, and/or violations of lines capability. With proper control, the DSTATCOM-SMES is capable of supplying the power system with both active and reactive powers simultaneously and very fast, and thus is able to enhance the dynamic security dramatically. A full detailed model of the DSTATCOM-SMES controller is proposed and a new control scheme is designed, comprising an enhanced frequency control scheme. The dynamic performance of the proposed control schemes is fully validated through digital simulation carried out by using MATLAB/Simulink.
