Grid-connected control strategy of energy storage system based on additional frequency control. 1. Existing flat/smooth control strategy. The power of the PV station is taken as the input signal. The output power of the ESS is generated to suppress the fluctuation of the PV/ESS station according to different time scales.
In brief, with the development of power electronic devices, high-power converters and large-scale energy storage technology are becoming mature, so the application of the latter, based on the centralized configuration, is more advantageous in the grid-connected new energy power generation.
Second, the distributed configuration is aimed at adjusting and controlling power of each wind turbine, so power and capacity of each storage system is small. The centralized configuration aims at adjusting and controlling the power of the farms, so the energy storage system boasts of larger power and capacity.
As shown in Fig. 6.2, the centralized configuration means that an independent energy storage system is configured at the exit bus of the wind farm, regulating and controlling the output power of the whole farm. The method is to control and adjust the output power from a macro perspective.
The centralized configuration does not change the existing control structure of the wind turbine, and it only needs to be relatively independent of the energy storage system that is connected to the exit bus of wind farm through an AC/DC converter to control the wind grid-connected power fluctuation.
The configuration of the storage system in the new energy grid is divided into two modes: distributed and centralized configuration. The configuration methods are widely applied in wind farms. The distributed configuration is applied on the excitation DC link of a wind turbine or on the output terminal of each wind turbine.
