Wind,light and hydrogen storage complementary uninterrupted power supply system

Abstract

The invention discloses a wind, light and hydrogen storage complementary uninterrupted power supply system. The power supply system comprises a wind power generation system, a photovoltaic power generation system, a control system, an inverter system, an energy storage battery system, a hydrogen fuel cell standby power generation system and a hydrogen production system. A part of electric energy generated by the wind power generation system and the photovoltaic power generation system is regulated and controlled by the control system, direct current is converted into alternating current through the inverter system, the alternating current can be used for supplying power to different loads of alternating current and direct current, redundant electric energy charges the energy storage battery system, and after the energy storage battery system is fully charged, excess electric energy enters the hydrogen production system to produce hydrogen; hydrogen produced by the hydrogen production system is injected into the hydrogen storage tank for storage; and meanwhile, the energy storage battery and the hydrogen fuel cell standby power generation system serve as two standby power supplies of the system, continuous power supply of the system under the extreme condition without wind and light power generation can be guaranteed, the safety and reliability of system operation are improved, and uninterrupted power supply is achieved.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a composite renewable energy power generation system that integrates various energy power generation technologies such as wind energy, solar energy, hydrogen fuel cell generators and storage batteries, and system intelligent control technology. Background technique [0002] As new energy generation forms, wind power and solar photovoltaic power generation have many advantages such as energy saving and environmental protection, short construction period and flexible investment. Due to the characteristics of stability and volatility, the power generation of the unit equipment is highly uncertain, which has a certain impact on the stability of power supply and power quality. [0003] Energy storage technology can largely solve the randomness and volatility of wind power generation, solar photovoltaic power generation and other new energy power generation, and can effectively adj...
