Abstract

Abstract: Superconducting magnet energy storage system (SMES) can achieve quick power response with the power grid, which can enhance the stability of power grid and improve the power quality. This paper introduces a 100 kJ/50 kW SMES including the superconducting magnet design, the cooling system, power conditioning system and the monitored control system. In order to verify the performance of this SMES, open-loop power regulation experiments are conducted. The following conclusions can be achieved through the above experiments, that SMES can respond very quickly to exchange power with the power grid. Based on the above analysis and tests and taking the topology of micro-grid demonstration garden of Yunnan electric power grid into consideration, experiment schemes are presented for the application of SMES in micro-grid, which aims to verify the performance and function of SMES when it is applied in micro-grid.

Key words: superconducting magnet energy storage (SMES), superconducting magnet, micro-grid, stability of power system
