This paper focuses on different-rating battery energy storage system (BESS) integrated into a microgrid. To improve the power quality and satisfy the requirements of power system, it is necessary to integrate different-rating BESS composed battery modules (BM) and power conditioning system (PCS) into the microgrid. The BESSs can supply suddenly changed loads, especially for sensitive loads that must have uninterruptible power supply. A new control strategy included slack mode control and load mode control is presented to enable the BESSs operate in two operation mode: the free-slack operation mode and the load-sharing operation mode. In the load sharing operation mode,the controller enable various load proportionally shared by two different-rating BESS parallelly operating without communication between them In the free-slack mode operation, the BESSs acting as a free-slack can adequately balance the active and reactive power of the microgrid to maintain the voltage and frequency at point of common coupling (PCC) to a desired level. The advantage of the proposed control method is that the unified controller is employed for the two operation mode without swithing between different controllers. Details of modeling of the BM and PCS and the corresponding control strategy are described. The effectiveness of the BESSs and proposed control method is verified through simulations and experiments.

W artykule omówiono bateryjny system gromadzenia energii BESS zintegrowany w mikrosiecią. W celu poprawy jakości energii łączy się systemy BESS z układami kondycjonowania PCS. System BESS działający jako układ zabezpieczający przed chwilowymi zanikami energii musi cechować się niezawodnością. Zaprezentowano nowa strategię sterowania łączącą tryb łagodny i tryb kontroli obciążenia. Zaletą metody jest że do sterowania stosowany jest zunifikowany kontroler bez potrzeby przełączania między różnymi kontrolerami. Skuteczność c metody potwierdziły symulacje i eksperymenty.
