摘要：
This paper presents a coordination scheme of super-conducting magnetic energy storage (SMES) and photovoltaic (PV) generation system for regulating the DC bus voltage in the low voltage direct current (LVDC) distribution systems. Firstly, the effect of AC grid faults on LVDC distribution system is analyzed. Then, the PV is designed to operate as the backup power of SMES by adjusting the control mode automatically according to the residual energy of SMES. The proposed scheme can regulate DC bus voltage in milliseconds and maintain the bus voltage during the whole fault process by taking use of both SMES and PV. A LVDC distribution system is modelled in PSCAD/EMTDC. Simulation results have demonstrated the feasibility and effectiveness of the proposed scheme.
