To smooth the long-term and short-term wind power fluctuations

a new coordination operation method of wind power and energy storage hybrid system based on the model predictive control (MPC) and low pass filter (LPF) is proposed. Based on the wind power forecasting results

the receding optimization is utilized to control the energy storage system every 15 min while a number of constraints are considered

such as the smoothing effects of grid-connected power

the state-of-charge (SOC) of the energy storage system and so on. Furthermore

the connection of MPC and LPF is established by compensating for the traditional LPF to ensure that the SOC catches up with the optimization track set by MPC. Finally

simulation studies demonstrate that the new method can not only smooth the 1 min and 10 min short-term fluctuations

but also control the SOC range in the 15 min to 4 h long-term time scales. This work is supported by National Key Technologies R&D Program (No. 2013BAA01B04).
