1.Solar and wind power is the most common form of natural resources, and inexhaustible renewable energy. 2.Solar energy and wind energy in time and areas are highly complementary.The strong sunlight in the day, the wind is very small, after the evening sun and light very weak, but due to changes in surface temperature and wind strengthened.In summer, intensity of the sun and the wind small, the winter sunlight intensity of weak and strong winds. Solar energy and wind power are complementary in time to wind and PV hybrid power generation system in resources with optimal matching. Wind-light complementary system is the best independent power resource conditions. 3.Wind-light complementary system according to user's electricity load condition and resource conditions for the rational allocation of system capacity,to guarantee the reliability of the power supply system, and can reduce the cost of power system.Whatever the environment and the electricity requirement, wind-light complementary system can make the optimized design system to meet the requirements of the customers. It should be said that wind and PV hybrid power generation system is the most reasonable independent power supply system. |
