Of all the power storage equipment UCAPs have small energy density, high power density as well as fast charge/discharge uniqueness. They also have additional charge/discharge cycles as well as higher deadly voltage per unit when compare to battery. All these individuality make UCAPs model alternative for provided that maintain to proceedings on the distribution grid which require high power for short spans of time. UCAPs have traditionally been limited to regenerative brake and wind power smooth applications. The main role of this study is in integrate UCAPs for a broader assortment of application like active/reactive power support, renewable intermittency smoothing, voltage sag/swell compensation as well as power quality conditioning to the distribution grid. Renewable intermittency smoothing is an application which requires bi-directional transfer of power from the grid to the UCAPs and vice-versa by charging and discharging the UCAPs. This application requires high active power support in the 10s-3min time scale which can be achieved by integrating UCAPs through a shunt Active Power Filter (APF) which can also be used to provide active/reactive power support. Temporary voltage sag/swell compensation is another application which requires high active power support in the 3s-1min time scale which can be provided integrating UCAPs into the grid through series Dynamic Voltage Restorer (DVR). All the above functionalities can also be provided by integrating the UCAPs into a power conditioner topology.
