Abstract
A system and a method for controlling a hybrid microgrid system (HMS) is disclosed. The HMS includes a WTG, an RSC, a GSC, a DC-link connecting the RSC and the GSC, a PV system that outputs a DC current to the DC-link, a rechargeable battery, a bidirectional BBC connected between the DC-link and the rechargeable battery, and a controller. The method for controlling the HMS includes: preparing a definition set including a characteristic element cand equations defining desired value c*, a fractional order sliding mode surface ζ, and a control law element u; monitoring c(t) and the HMS status; calculating the equations based on monitored information; and controlling the HMS based on the u(t) calculated and in accordance with a global sliding mode control with fractional order terms. The ζcomprises a fractional time integral and fractional time derivative of e(t), where e(t)=c(t)−c*(t). The u(t) satisfies when ζ(t)≠0.
