Abstract: This research presents several control methods for applications of energy storage systems (ESSs) in smart grid. For low-voltage distribution networks with high penetration of solar photovoltaics and plug-in electric vehicles (EVs), the systems will encounter voltage rise/drop issues during peak generation/load period. First, distributed ESSs are proposed to solve these voltage problems through a coordinated control method, which ensures voltage regulation while effectively utilizes available capacities of ESSs during daily operation. Second, the research work is extended to utilized distributed electric vehicle chargers (EVCs) for voltage regulation in distribution networks. Algorithms for determination of vehicle-to-grid operation of the plugged-in EVs and the real and reactive power outputs of EVCs are proposed. Furthermore, the application of ESSs in islanded microgrid is investigated. In order to achieve power balance and uninterrupted power supply in the islanded microgrid, a hierarchical control scheme is proposed to coordinate all available units. The proposed control methods in the research are verified under various system topologies and different types of PV and load data.
