An Intelligent Optimal Management System of Household Comprehensive Energy Based on Model Predictive Control

Abstract

The present invention discloses a model predictive control-based home integrated energy intelligent optimization and management system. According to the technical scheme of the invention, the structural features of a home energy local area network and the operating characteristics of all devices are analyzed, and then an economic operation scheme for the optimal energy management of the system is constructed. The system comprises a data acquisition module, a prediction module, an energy management and optimization module, a real-time scheduling optimization module, and a control and communication terminal module. Based on the model predictive control method, the online rolling optimized solution is conducted according to the energy consumption requirements of a load within different time periods, the real-time price of energy, and the state information of distributed power generation equipment and energy storage equipment. Therefore, the optimum allocation of the energy, and the economic and safe operation of the system are realized. Based on the internet technology, a network service platform is set up. Through a handset app, the functions of on-line monitoring, remote control and the like are realized. In this way, a user can know the energy consumption condition of home energy and the operating states of all intelligent devices at any time, so that the remote monitoring is realized for the user. The system provides a novel economic energy management mode for the user.

Description

technical field [0001] The invention relates to the energy Internet, in particular to a family comprehensive energy intelligent optimization management system, which belongs to the technical field of energy intelligent management and control. Background technique [0002] The progress of modern civilization relies on the drive of a large number of various energy sources. Modern people use energy all the time in their lives, and our daily necessities of life are all closely related to water, electricity, natural gas, heat and other energy sources. The energy consumption of residents is increasing day by day, but the utilization rate of energy is not high, and the problem of single power supply is becoming more and more prominent. How to reduce energy consumption intensity and improve energy utilization rate through energy interconnection is an urgent task. [0003] At present, a smart energy Internet that integrates new energy technology and information technology has emerge...
