Massive applications of the power electronic devices and non-linear loads lead to various power quality problems during the microgrids grid-connecting. Aiming at improving power quality of micro-grid, the structure of SCs’ main circuit and control circuit are designed. The model of super-capacitor energy storage system (SCESS) is established. A simulation model of micro-grid is also built up by using MATLAB and the simulation is conducted for different situations. Moreover, under Goldwind micro-grid platform, according to the result of MATLAB modeling and simulation, the SCESS effectively improves the transient power quality of the system.
