Energy management method and system based on Markov decision process

The invention discloses an energy management method and system based on a Markov decision process, and the system carries out the modeling of a smart home, and builds a unique cost calculation system. Meanwhile, a measurement standard of privacy protection degree in the system is defined, a rechargeable battery is introduced for peak shifting charging and discharging, and real-time power utilization information of a user is covered. An optimization problem for balancing privacy protection and cost saving is constructed by using a Markov decision process, and the problem is solved by using a Sarsa algorithm. Finally, the most appropriate energy management strategy can be found according to the personalized requirements of the user, the system cost is minimized while the privacy security is improved, and the optimal configuration of resources is realized. According to the energy management system and the energy management method, privacy protection and cost saving are both considered, and the system cost can be
