An optimal allocation model of energy storage capacity for combined wind-storage system is studied. With the maximum total system revenue as the objective function, the influencing factors and their sensitivities of the energy storage capacity allocation of the combined system are analyzed.
Additionally, from the standpoint of capacity allocation, the battery's service life can be reasonably estimated according to its life attenuation mechanism, and the energy storage capacity allocation that meets the wind power smoothing requirements can be achieved in combination with the economic cost analysis.
The wind-storage combined system, as illustrated in Fig. 1 incorporates the battery-supercapacitor HESS at the wind farm's outlet. The power controller of the energy storage system regulates its output power by collecting the data on wind power output, grid-connected power, and SOC to meet the requirements for wind power integration.
A battery life model considering effective capacity attenuation is proposed. Hybrid energy storage system (HESS) can cope with the complexity of wind power. But frequent charging and discharging will accelerate its life loss, and affect the long-term wind power smoothing effect and economy of HESS.
For capacity allocation, the capacity of energy storage equipment determines its ability to effectively stabilize wind power fluctuations. In particular, the battery's life attenuation, caused by cycle aging and calendar aging, can affect its long-term wind power smoothing ability.
The proposed model and method are validated by taking the combined wind turbine and storage system as an experimental object, based on the typical daily data extracted using the improved k-means clustering algorithm. Energy storage uses battery storage, and the cost of battery unit capacity is 1300 yuan/kWh.
