Outdoor energy storage type wind-solar complementary off-grid power generation system

Abstract

The invention discloses an outdoor energy storage type wind-solar complementary off-grid power generation system which comprises a power generation module, an energy storage module and an off-grid inverter. The power generation module comprises a solar energy unit, a wind energy unit and a wind-solar complementary unit, the solar energy unit and the wind energy unit are separately connected with the input end of the wind-solar complementary unit, and the output end of the wind-solar complementary unit is connected with the energy storage module. The energy storage module comprises a phase change energy storage battery, the input end of the phase change energy storage battery is connected with the power generation module, the output end of the phase change energy storage battery is connected with a load device, the wind-solar complementary unit comprises a wind-solar complementary controller, and the wind-solar complementary controller is an intelligent MPPT module controller integrating solar energy control, wind energy control and output control. Natural green energy is used, external power such as mains supply is not needed, power supply cables do not need to be buried or erected, and the advantages of being green, energy-saving and environmentally friendly are achieved.

Description

technical field [0001] The invention relates to the field of renewable energy power generation, in particular to an outdoor energy storage wind-solar complementary off-grid power generation system. Background technique [0002] Human production and living energy currently mainly rely on fossil energy, including oil, natural gas, coal and other naturally formed, non-renewable resources. Human beings are facing the crisis of fossil energy depletion, and energy shortage is one of the problems that human beings need to solve urgently. Therefore, countries all over the world are vigorously developing renewable energy. Among them, solar energy and wind energy have strong complementarity in terms of time and area, mainly manifested in the strong sunlight intensity and low wind during the day, and weak light intensity at night, but the wind energy is strengthened due to the large surface temperature difference. In summer the sun is strong and the wind is low; in winter the sun is ...
