Abstract

The invention provides a wind-solar-energy-storage integrated air conditioning system based on a common direct-current bus and a control method thereof, and belongs to the field of air conditioning systems. The system comprises a direct-current bus, an alternating-current power grid which is electrically connected to the direct-current bus and used for providing electric energy for the direct-current bus, a solar photovoltaic cell panel, a wind driven generator, and an air conditioning system which is electrically connected to the direct-current bus. The system further comprises a DC control selector which is used for collecting the electric information of the direct-current bus, the alternating-current power grid, the solar photovoltaic cell panel and the wind driven generator and configuring the alternating-current power grid, the solar photovoltaic cell panel and the wind driven generator according to the electric information so as to enable the voltage provided by the direct-current bus to be within the voltage range required by the air conditioning system. Light energy and wind energy are comprehensively utilized, dependence of the air conditioning system on an alternating-current power grid is reduced, and system operation stability is improved.

Description

technical field [0001] The invention relates to the field of air-conditioning systems, in particular to a wind-solar-storage integrated air-conditioning system based on a common DC bus and a control method thereof. Background technique [0002] The solar-storage air-conditioning system is an air-conditioning application system that collects and absorbs new energy locally. The solar-storage air-conditioning system has been widely used. Compared with the mains-powered air-conditioning system, the solar-storage air-conditioning system is more energy-saving and environmentally friendly. But there are also some deficiencies, which lead to the limitation of the application of the air conditioning system. [0003] For example, when the solar-storage air-conditioning system is applied in the evening and morning, it has the following characteristics: the sunlight is insufficient at night and in the morning, and the photovoltaic power generation system is in a stopped state. At this ...
