Problems solved by technology

However, the traditional photovoltaic power generation system has weak ability to withstand disturbances, and due to the low energy density, volatility and randomness of solar energy, the risk of isolated grid system operation is increased, which can easily lead to overcharging of energy storage systems and heat storage systems , over-storage and over-discharge problems, thereby reducing the service life, therefore, effective energy management is of great significance

Abstract

The invention belongs to the field of new energy comprehensive utilization, and provides an energy management system and method based on household combined heat and power supply. According to the energy management system, a central controller is used as a core, a photovoltaic battery assembly, an energy storage system and a heat storage system are subjected to unified centralized control, operation data of the photovoltaic battery assembly, an energy storage battery and a heat accumulator are monitored in real time, the working modes of the energy storage system and the heat storage system areswitched according to the monitored operation data, the problems of overcharge, overstorage and overdischarge of the energy storage battery and the heat accumulator can be avoided, the service life is prolonged, the energy management system can operate more safely, efficiently, economically and reliably, and meanwhile solar resources can be utilized to the maximum extent.

Description

Technical field [0001] The present invention relates to the field of new energy utilization, particularly relates to an energy management system and method based household cogeneration supply. Background technique [0002] Power system is power plants, transmission lines substation, power supply and distribution, and other aspects of the composition and the production of electrical energy consumption of the system. Its function is the primary energy is converted into electrical energy by the power generation means nature, and then by transmission, and distribution substation supplying electric power to each user, to provide the desired electrical and thermal life. But in remote areas, especially in the pastoral herders need to migrate each year from a remote pasture to another pasture, traditional heating method can hardly meet their needs. Isolated Network systems can operate independently outside the power grid, therefore, usually solitary network system can not access the peop...
