The invention provides a control method and equipment for a super-capacitor in a micro-grid. The control method for the super-capacitor comprises the following steps: a detection unit detects a real-time voltage and a real-time current of a micro-grid bus; a real-time power calculation unit calculates active power and reactive power based on the real-time voltage and the real-time current; and a discharging control unit controls discharging of the super-capacitor according to the active power and the reactive power, so that a voltage of the micro-grid bus can be adjusted. The control method for the super-capacitor in the micro-grid provided by the embodiment of the invention is adopted to control the super-capacitor, so that the advantage of quick start of the super-capacitor can be fully exerted, the bus voltage can be rapidly restored to normal in case of fluctuations of the micro-grid, and the power quality can be better improved.
