The Capacity Optimization of Hybrid Energy Storage System for Wind Power Smoothing

AbstractWind power system plays an important role insmoothing wind power fluctuations. In consideration of limitedadvantage of single energy storing dielectric, the hybrid energystorage system has a good application prospect with its meritscomplementation. In this paper, firstly the types of power andenergy storage are used to establish the hybrid energy storagepower system. Considering their characteristics, the energystorage power system model is established, which can combineadvantages of different energy storage devices. And then,according to the constraint of charging and discharging powerrate of two mediums and capacity contrast constraint, energystorage capacity optimization model is set up aiming to minimizethe sum value of running cost and construction cost. At last, thealgorithms and solving steps are proposed. The analysis on actualoperating data of wind power plant can verify the effective andreasonability of the proposed method5 Halama
