Energy storage technology plays an important part in wind power generation system integrated with energy storage device. This paper researches on the control strategy of smoothing the output curve of wind power. Take advantage of high power density ultra-capacitor to achieve this objective according to a basic principle that the desired wind power approaches the average value of wind output in the previous period. Meanwhile in order to make the dispatch more flexible, SoC level of ultra-capacitor and fluctuation of wind power are considered to optimize the time constant in real time. The wind power generation system integrated with energy storage device is simulated in the PSCAD/EMTDC software. The simulation results demonstrate the efficacy of proposed control strategy.

Cloud Coverage

Consideration of the use of the major types of energy storage is attempted in this paper to mitigate the effects of power transients associated with grid-tied CPV systems due to fast-moving cloud coverage. The approach presented is to buffer intermittency of CPV output power with an energy storage device (used batteries) purchased cheaply from EV owners or battery leasers. When the CPV is connected to the grid with the proper energy storage (54kW), the main goal is to smooth out the intermittent solar power and fluctuant load of the grid with a convenient control strategy. Actual summer 2011 data collected at the Center for Energy Research (CER), UNLV are utilized for the purpose of this study. Hence, appropriate simulations have proven that not only the unit ( Amonix 7700) is capable of putting onto the grid during the day time a constant amount of power (20kW), but also is able to shift the less valuable off-peak electricity to the on-peak time (1pm to 7pm), where the electricity price is much better.

Air Compression

In this study, a new idea of wind powered air compression system is introduced. Present study relates to an air compression system having a characteristic of storing wind energy. A transmission system transfer the wind power to an air compression system is also studied. The air compressed system is comprised of a windmill, an energy storage device, an air compressor, and an air storage device for collecting the wind energy and storing the energy in a form of compressed air. In order to find the basic characters of the system, several experiments were done and a transmission system was selected and modified.
