Power Management and Control Strategy in Standalone DC Microgrid alongwith SMES Solenoid Coil

This paper investigates the integration of Superconducting Magnetic Energy Storage (SMES) System into the standalone Permanent Magnet Synchronous Generator (PMSG) based on Variable Speed Wind turbine (VSWT) in DC Microgrid system. The primary aim of SMES system is to retain power balance by drawing power during high wind generation and to extricate it during low power generation. An effective control approach is produced for bi-directional DC-DC converter to balance the output power of the wind turbine depending on the load, consequently decreasing the capacity of the DC-DC converter system. To certify that the system can exploit under island conditions, a coordinated strategy for the SMES system, wind turbine and demands is proposed. Detailed simulation studies implemented in PSCAD/EMTDC emphasize the superior robustness of applying SMES coil in the DC Microgrid for damping down the wind power intermittency and for enhancing its dispatchability.
