Coordinate Control

In a power system with wind farms, the point of common coupling (PCC) usually suffers from voltage instability under large wind speed variations and the load impact. Using the internal converter of a doubly fed induction generator (DFIG)-based wind turbine to provide voltage support auxiliary service is an effective scheme to suppress the voltage fluctuation at PCC. To satisfy the reactive power demand of the connected grid, an active voltage coordinate control strategy with the hybrid energy storage system of the wind farm is proposed. The dynamic reactive power balance model is established to show the interaction between the reactive power limitation of the wind farm and the reactive power compensation demand of the grid. This indicates the initial conditions of the active voltage coordinate control strategy. According to the critical operating point and the operation state of the DFIG, the active and reactive power coordinate control strategy composed of active ω-β coordinate control and active β control is proposed to enhance the reactive power support capability and stabilize the grid voltage. To compensate the active power shortage, an auxiliary control strategy based on the hybrid energy storage system is introduced. The simulation results show that the proposed strategy can suppress the voltage fluctuation effectively and make full use of primary energy.

In this paper, the wind power fluctuation is divided into three categories. For the purpose of balancing all kinds of wind power fluctuation to enhance the penetration levels of wind power, we propose an active-parallel hybrid energy storage system (APHESS). The APHESS is composed of a battery, a supercapacitor, and two charge-discharge controllers. By combining the battery with the supercapacitor, the APHESS obtains the enhanced energy storage performance. Therefore, the investment cost can be reduced. By the reasonable design on the operation mode of APHESS, the APHESS can interchange power precisely with the wind power system. Furthermore, the battery and supercapacitor can suppress separately different kinds of wind power fluctuation to make their own energy storage properties fully utilized. The APHESS can be widely used in wind farm for the real-time regulation on wind power

Hybrid Energy Storage System

According to the demand of wind farm power fluctuations stabilize and the characteristics of hybrid energy storage system. Taking vanadium redox flow battery (VRB) and supercapacitor (SC) as research object, a hybrid energy storage system optimal configuration model is builted. Combined with expert systems and improved genetic algorithm proposed a hybrid energy storage system to optimize the allocation method. The method first established desire output curve of the wind farm based on grid energy saving efficiency and static voltage stability indicators, then introduce coordinate control strategy based on expert system to improved genetic algorithm to get the result of optimal configuration and verify the correctness of this model and method. Finally, analysis the performance of VRB and SC in a typical days wind farm output situation, verify the conclusions of experts coordinated control strategy can extend the vanadium battery life.
