Novel wind and photovoltaic hybrid power generating system with high power generating efficiency

Abstract

The invention relates to the field of new energy resources, and particularly relates to a novel wind and photovoltaic hybrid power generating system with high power generating efficiency. With the increase of the strength of national energy conservation and emission reduction, the national energy policy gradually tends to the aspect of renewable energy utilization, and as renewable energy distributed power generation, the wind and photovoltaic hybrid power has important functions. At present, wind and photovoltaic hybrid power generation is affected by immature technical factors such as poor gentle wind starting performance, low power generating efficiency, low photoelectric conversion rate, unchanged dip angle, the wind and photovoltaic power generation has the defects of low integral cost performance, small loading capacity and the like, and cannot well meet the demands of rapid development of the distributed power generation market, thus limiting the large-scale promotion on other markets. The invention provides a technology capable of adjusting the dip angle of a photovoltaic module, so that the photovoltaic module is capable of receiving more direct radiant quantity of the sun, and compared with the wind and photovoltaic hybrid power generation with same loading capacity but unchanged dip angle, the wind and photovoltaic hybrid power generating system has the advantage that the generating capacity is additionally increased by about 40%.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a novel wind-solar complementary power generation system with high power generation efficiency. Background technique [0002] At the Paris climate summit at the end of 2015, China stated that it would reduce carbon dioxide emissions per unit of GDP by 40% to 45% from 2005 levels by 2020. Under the background of further increasing pressure on energy conservation, emission reduction and environmental protection in the whole industry, in order to achieve the goal of carbon emission reduction, my country is rapidly reducing its dependence on coal-fired power generation, gradually reducing coal-fired power generation, and increasing the use of renewable energy will be The development direction of the country's future energy policy. Therefore, as an important means of energy saving and emission reduction, wind-solar complementary distributed power generation has been paid more and more attent...
