  • Grid voltage stabilization system
    Patent number: 11258257
    Abstract: A grid voltage stabilization system according to an embodiment of the present invention comprises: a power generation device for generating power by using a new and renewable energy source, and supplying the generated power to a grid; an energy storage system (ESS) for, according to a command value, storing power generated in the power generation device in a battery, or supplying power stored in the battery to the grid in the form of active power and reactive power; and a power management system (PMS) for, when a voltage value of the grid is out of a reference range, controlling the magnitude of the reactive power to be supplied to the grid such that the command value is changed according to the voltage value of the grid to enable the voltage of the grid to be within the reference range.
