GRID CONNECTED SYSTEM FOR PHOTOVOLTAIC GENERATION USING ENERGY STORAGE SYSTEM

摘要

The present invention relates to a grid connection system for solar light generation. The grid connection system for solar light generation according to an embodiment of the present invention comprises: one or more solar light modules for receiving solar light, and generating direct current power; one or more micro inverters respectively connected to one or more solar light modules, and converting direct current power generated from the solar light module into alternating current power; an energy storing device for receiving and storing the alternating current power converted from the micro inverters; and a panel board provided with alternating current power from the micro inverters, the energy storing device, and an external grid power source to be provided to a load side. The panel board provides alternating current power provided from the micro inverters to the energy storing device. According to the present invention, the grid connection system for solar light generation measures power generated from the solar light module, power supplied to the load, and control power supplied from the energy storing device, and performs an operation for reducing an power used amount and reducing peak power according to a solar light generation state and load power consumption, so home energy may be managed.
