    Abstract: A power system for connecting a power source, an energy storage unit and a grid includes a power inverter, an energy storage power converter and a controller. The power inverter is electrically coupled to the power source through a DC bus and converts DC power from the DC bus to AC power output to the grid. The power converter is electrically coupled between the DC bus and the energy storage unit and stores power in the energy storage unit and discharges power from the energy storage unit. The controller controls the power converter to store excess power from the power source that cannot be output to the grid in the energy storage unit, and control the energy storage power converter to discharge power stored in the energy storage unit to the power inverter to output to the grid.

    Abstract: A power system and method for performing a blackstart on a microgrid. The power system includes at least a first power converter and a second power converter. The first power converter comprises a first controller having a plurality of startup sequences for performing the blackstart. The second power converter is electrically coupled to the first power converter at a point of common coupling. During the blackstart, the first controller is configured to select and perform one of the plurality of startup sequences according to a point at which the second power converter is within the second power converter's startup sequence during the blackstart. The first controller selects the one of the plurality of startup sequences according to a microgrid voltage at the point of common coupling.

    Abstract: A power system having a plurality of operating modes including an active mode and an active standby mode includes a power converter and a controller the power converter is configured to adapt a power supply to a desired output, and the power converter includes a plurality of semiconductor switches that receive a gating signal when the power system is in the active mode such that the power converter is in a gating state. The controller controls the power converter in the active mode and the active standby mode, and the controller is configured to: while the power converter is synchronized to the grid, determine whether the power system should enter into the active standby mode in which the power converter is in a non-gating state; when it is determined the power system should enter into the active standby mode, control the power converter to be in a non-gating state such that the power system is in the active standby mode.

    Abstract translation: 具有主动模式和主动待机模式的多种操作模式的电力系统包括功率转换器和控制器，所述功率转换器被配置为使电源适配于期望的输出，并且所述功率转换器包括多个半导体开关 当电力系统处于活动模式时，其接收选通信号，使得功率转换器处于选通状态。 控制器控制电源转换器处于主动模式和主动待机模式，控制器配置为：电源转换器与电网同步时，确定电源系统是否应进入主动待机模式，在此模式下，电源转换器 处于非门控状态; 当确定电源系统进入主动待机模式时，控制电源转换器处于非门控状态，使电源系统处于主动待机状态。
