Abstract: An output controlling apparatus of an energy storage apparatus for a reliability of an output of a photovoltaic power generation is provided. The output controlling apparatus includes a power generation amount predictor configured to predict a next day's power generation amount of a photovoltaic power generator, a target output generator configured to determine a target output based on a charging state of an energy storage apparatus used for a photovoltaic power generation, a real-time output criterion generator configured to generate an output criterion used for outputs from the photovoltaic power generator and the energy storage apparatus to a system in units of time based on the target output and the charging state of the energy storage apparatus, and a charging/discharging controller configured to control charging and discharging of the energy storage apparatus such that an output to the system follows the output criterion.

Abstract: An uninterruptible power supply apparatus and method. The uninterruptible power supply apparatus includes a first generator, an energy storage, a first power converter connected to the energy storage, a second power converter connected to the energy storage, a first switch connected to the first power converter and a first load, a second switch connected to the second power converter, the first generator and a second load, and a third switch connected to a power grid, the first generator, the second power converter, the first switch and the second switch. In a normal state in which the first switch and the third switch are connected, the power grid supplies power to the first load or the second load. In an independent operating state in which the third switch is turned off, the first generator or the energy storage uninterruptibly supplies power to the first load or the second load.
