Wind and photovoltaic hybrid power generation system

Abstract

The invention discloses a wind and photovoltaic hybrid power generation system. The system comprises a power generation unit, a control unit and an energy storage unit. The power generation unit comprises a wind driven generator and a solar panel; the control unit is a coordination controller; the energy storage unit is a storage battery pack; the wind driven generator and the solar panel are connected with the coordination controller through a DC / DC conversion circuit; the coordination controller is connected with the storage battery pack; the storage battery pack is connected with electricalequipment through a DC / AC inverter. The beneficial effects brought by the invention are that the power generation device makes the most of the natural complementarity of wind energy and solar energy,thereby reducing the consumption of traditional energy sources and ironing out the congenital defects of renewable new energy sources; the system employs the wind and photovoltaic hybrid power generation, and the coordination controller is installed; the system achieve the uninterrupted power supply through combining with some energy storage battery devices, thereby effectively reducing the dependence on fossil energy sources.

Description

technical field [0001] The invention relates to the technical field of multi-energy complementary energy storage and energy supply equipment, in particular to a wind-solar complementary power generation system. Background technique [0002] With the increasing consumption of traditional energy sources such as coal and oil, in recent years, countries have continuously developed new renewable energy sources, striving to form a pattern of multi-energy complementarity, and adopting multiple energy sources to complement each other according to different resource conditions and energy-using objects , to alleviate the contradiction between energy supply and demand, reasonably protect natural resources, and promote a virtuous cycle of the ecological environment. The world oil crisis has made many countries realize that it is very dangerous to rely on one or two major energy sources, and the ecological and environmental problems caused by the extensive use of fossil fuels are becomin...

AI Technical Summary

Problems solved by technology

However, wind-solar hybrid power generation is affected by wind speed and light intensity, so the electric energy generated by the two kinds of energy has great fluctuation and randomness, which brings great difficulties to the efficient use of electric energy.
