Evaluation of the hierarchical control of distributed Energy Storage Systems in islanded Microgrids based on Std IEC/ISO 62264

In this paper, a decentralized control methodology based on hierarchical control levels is investigated. In recent years, efforts have been made to develop standards for Microgrids (MGs), and the decentralized control method evaluated here is based on the IEC/ISO 62264 standard. Since the main challenge to decentralized control in Battery Energy Storage Systems (BESSs) is the different levels of stored energy, a modified droop control is used here to share the power between the different storage units, based on the energy level of each unit. The power coefficients of the droop control are set inversely proportionally and directly proportionally, respectively, to the state of charge (SoC) of each battery unit during discharging and charging mode. To evaluate this decentralized method based on the IEC/ISO 62264 standard, PSCAD/EMTDC software is used.
