Hybrid energy storage system

Abstract

A hybrid energy storage system includes a solar power system, a wind power generation system, an energy conversion device, an inverter, a DC power storage system, an intelligent control device, a smart green home, a wind energy recovery device, a thermal energy storage system, an ice storage system, a filtration system, and drinking water equipment. Solar and wind power generation is stored in the DC power storage system via the energy conversion device and then used by small household appliances through the inverter. It can also be connected in parallel with a power company. Hot air generated by the smart green home is fed into the wind power generation system via the wind energy recovery device. Excess heat is recovered by the thermal energy storage system, and wastewater is treated by the filtration system before being used for drinking water equipment or livestock farming. It can also be used by the ice storage system to produce ice for energy storage. Through unified management by the intelligent control device, the system achieves high energy efficiency and net-zero emissions, combining environmental and economic benefits.
