Distributed wind-solar complementary water storage power generation system and power generation method

Abstract

The invention discloses a distributed wind-solar complementary water storage power generation system and method, and belongs to the technical field of distributed power generation. The distributed wind-solar complementary water storage power generation system comprises a low-level water storage tank; the high-level water storage tank is used for storing water energy; the lifting pump is used for conveying water in the low-level water storage tank to the high-level water storage tank; the solar photovoltaic power generation device is used for providing electric energy for the lifting pump; the water in the high-level water storage tank flows into the low-level water storage tank to generate electricity; according to the distributed wind-solar complementary water storage power generation system and method, batteries are not used, the maintenance cost is reduced, good power generation and energy storage effects are achieved, the system and method are better applied to distributed photovoltaic power generation, and particularly the system and method can be widely installed and used in places such as residential quarters, office buildings and factories.

Description

technical field [0001] The invention belongs to the technical field of distributed power generation, and in particular relates to a power generation system and a power generation method for distributed wind-solar complementary water storage. Background technique [0002] At present, distributed photovoltaic power generation, wind power generation, and hydropower are all green power and will gradually become the mainstream of power supply; but all three power generation methods have shortcomings, among which photovoltaic power generation cannot generate electricity at night; wind power cannot be used directly , it is necessary to use a rectifier device to convert the generated electricity into direct current, store it in the battery, and then use it after inverting, but because the battery life is limited, the maintenance cost is high; hydropower is limited by water sources and geographical locations, and cannot be applied well in In distributed power generation, there is cur...
