The solar-wind complementary system

combining advantages of wind and solar energy

plays an important role in solving the current energy shortage and economic environmental protection issues. In order to find out how to maintain the optimal power of solar-wind complementary system

the influence of such parameters as wind speed

wind wheel radius

load

temperature and illumination intensity on the power of wind and solar energy were studied. In addition

based on the maximum power point tracking theory

the power demand of a household was optimized

and the characteristics of wind

solar and battery output power were discussed. The results show that

the generation output of the solar-wind complementary system is stable. At noon time in a day

the power output is abundant and don't require battery

implying the light and wind is enough during this time. However

in other time except 20:00~24:00 at night

the electricity basically needs to be supplied by the battery.
