Micro grid consists of micro power supply, load, energy storage and energy manager. Energy storage takes place in the microgrid in the form of: it is connected to the DC bus of the micro power supply, the feeder containing important loads, or the AC bus of the micro grid.
At present, the application of super capacitors in power systems has attracted more and more attention. The following is the application of super capacitor in smart grid.
1.Used as energy buffer device
Super capacitor energy storage system can effectively solve this problem by storing excess power from the power supply during low load and feeding back to the micro grid to adjust the power demand during peak load. The high power density and energy density of super capacitors make it the best choice for handling spike loads, and only as much energy as the spike load needs to be stored using super capacitors.
2.Improve the power quality of micro grid
The energy storage system is a very important role to improve the power quality of micro grid. Through the inverter control unit, the reactive power and active power provided by the super capacitor energy storage system to the users and the network can be adjusted to improve the power quality. Since super capacitors can quickly absorb and release high power, it is very suitable to be used in the power quality regulation device of micro grid to solve some transient problems in the system, such as transient blackout, sudden voltage rise and voltage drop caused by system fault, then super capacitors are used to provide fast power buffer, absorb or replenish power, provide active power support for active or reactive power compensation to stabilize and smooth the fluctuation of grid voltage.
