Title: SYSTEM FOR CONTROLLING TRACKING OF MAXIMUM POWER POINT OF PHOTOVOLTAIC ARRAY, AND PHOTOVOLTAIC AIR-CONDITIONING SYSTEM
Abstract:
A system for controlling the tracking of the maximum power point of a photovoltaic array, and a photovoltaic air-conditioning system. The system for controlling the tracking of the maximum power point of a photovoltaic array comprises: a photovoltaic array for converting solar energy into direct current; a combiner box for combining the direct current converted by the photovoltaic array; a converter for converting the direct current combined by the combiner box into alternating current and transmitting same to an electric supply; an inverter for converting the direct current combined by the combiner box into alternating current and transmitting same to an electric appliance load; and an upper layer control module for controlling the converter to track the maximum power point of the photovoltaic array or controlling the inverter to track the maximum power point of the photovoltaic array. The control system resolves the problem in the related art that it is difficult for the system for controlling the tracking of the maximum power point of a photovoltaic array to achieve flexible switching among multiple modes of the system.
