The invention relates to an off-grid photovoltaic air conditioner self-
adaptive control system and method based on rolling self-learning, and aims to solve the problems of low power supply reliability, large battery loss, inflexible
temperature control, weak adaptability and the like caused by poor matching between an existing off-grid
photovoltaic system and an air conditioner load. The method mainly comprises the steps that parameters are collected in real time, loads are calculated, and
air conditioning unit operation frequency bands of the off-
grid system are dynamically divided based on the
temperature difference; constructing a multi-target model for guaranteeing power supply, prolonging the service life of the battery and optimizing the
thermal comfort of the off-
grid system, and adaptively adjusting the target by utilizing a dynamic
weight coefficient; the optimal sequence is solved through rolling time window optimization, and the off-grid regulation and control strategy is adjusted in real time in combination with
temperature gradient feedback. According to the method, the energy dynamic matching efficiency in the off-grid supply and demand
system can be improved, power supply is guaranteed, fine adjustment of
temperature control is achieved, harmful charging and discharging are limited based on state optimization, loss is reduced, the service life is prolonged, and compared with a traditional regulation and control strategy, the method has remarkable advantages in reliability, comfort and economical efficiency.
