Influence of fixed energy storage proportion on wind power transmission capacity

In this paper, the economic impact of fixed energy storage ratio on wind power centralized transmission capacity planning is explored based on EES's suppression control strategy and operation mode. Firstly, the effects of different control strategies and operating modes on suppressing fluctuations of wind power are contrast and analyzed. Then, transmission capacity of the wind power base is planned and optimized by using the suppressed wind power curve. Finally, based on the planned and optimized transmission capacity, these different strategies and modes described previously influencing on the economy of the transmission project are further explored. The result shows that the control strategy with better suppression effect can increase the transmission capacity obviously and the centralized operation ESS under the same control strategy can significantly improve the efficiency of the energy storage as well as the income of the transmission project. © 2020, Solar Energy Periodical Office Co., Ltd.
