What is Super-Capacitor

Chapter 5
Handbook of Research on New Solutions and Technologies in Electrical Distribution Networks
It is a short-term storage system used to store energy in case of excess and provide energy in case of lack in order to ensure the balance between production and consumption.

Abstract
In this chapter, a control strategy for a Renewable Distribution Generator (RDG) operates in grid-connected and standalone mode is suggested. This RDG is made up of a wind generator associated with a Super-Capacitors (SC) considered as a storage system. The study investigates a control scheme for RDG integrated into power electrical system to maintain the voltage and the frequency of the grid in an allowable range and to ensure the continuity of power supply in case of grid faults. The proposed control strategy has three parts: a vector control of the wind generator to extract the maximum power; the control of the DC bus voltage by inserting the SC; and a droop control loop proposed to ensure the grid stability. The simulation results demonstrate the reliability of the control system.
