Abstract

A hybrid renewable energy and energy storage system power supply system and a control method thereof integrate an electrochemical energy storage device with a mechanical energy storage device, and then match a solar photovoltaic and wind power generation system, and are grid-connected with a mains supply. In the control concept, an AC-DC is supplied preferentially to an AC-DC load, to reduce the conversion loss. The power supply system allows residence, base stations or computer rooms to be electricity self-sufficient, can conduct electric power trading with electric power companies when being grid connected with the mains supply, can avoid electric transient interruption during power outage and can also ensure a certain degree of power supply.

Description

technical field [0001] The present invention relates to the application field of micro-grid technology, in particular to a hybrid renewable energy and energy storage system power supply system and its control method, which can be combined with iEN (Intelligent Energy Network) intelligent energy-saving service monitoring system for energy management services, and can be used in Power generation equipment for residences, base stations or computer rooms is one of iEN's future development technologies. Background technique [0002] In view of the energy storage and energy supply system integrating natural energy in the previous proposal, the previous proposal is applied to the energy storage and supply system for converting wind and solar energy into electric energy, heat energy and cold energy. In addition to storage and supply, heat and cold energy are generated without the need for additional electricity to supply air-conditioning cooling and hot water needs, and make full us...
