Electric-power-distributed energy storage device and control system thereof

Abstract

The invention discloses an electric-power-distributed energy storage device and a control system thereof. The energy storage device and the control system thereof comprise a master system control unit, one or more electric power generating devices, one or more energy storage units corresponding to the electric power generating devices in quantity, one or more generating / energy storage control units corresponding to the electric power generating devices in quantity, an inverter unit and a off-grid / grid-connected control unit. The electric-power-distributed energy storage device and the control system thereof solve the problems that a photovoltaic generation system can reduce solar energy utilization efficiency because of a short plate effect of a solar battery, and the existing energy storage power station occupies a great deal of land resources and is high in maintenance cost but has low benefits.

Description

technical field [0001] The invention relates to the fields of electric energy storage, off-grid and grid-connected inverter power generation, etc., specifically refers to storing solar energy and grid electric energy in energy storage devices (such as battery packs), and then off-grid or grid-connected inverter when needed A control system for power generation. Background technique [0002] As the world's population increases and people continue to strive for a higher standard of living. The demand for energy will continue to increase and the challenge is how to provide this reliable and sustainable source of energy while maintaining respect for the environment. Coal-fired power generation and other fossil fuel sources of energy are finite resources, however, they also result in adverse environmental impacts. While it is clear that renewable energy can certainly play a role when used in conjunction with traditional energy, it is also clear that renewable resources cannot i...
