A Design Scheme of Smart Energy Internet

Abstract

Breaking through the limitations of traditional power grid, photovoltaic panels, air source heat pump, ground source heat pump, lithium battery energy storage system, intelligent charging pile and other equipment are installed on the roof of ChengBi campus, and the energy consumption of dynamic distribution units is monitored through the energy management system. To realize the protection of new energy and ecological environment. 1 Project source and background at home and abroad Under the background of over exploitation and utilization of non-renewable energy, and the serious damage to ecological environment caused by large amount of greenhouse gas emissions, a clean energy utilization scheme with solar power generation as the core is studied. It is required to make full use of solar energy to alleviate the environmental problems caused by the use of traditional energy, optimize the power supply and distribution scheme of energy users, and reduce energy waste. The first smart energy Internet system was built in ChengBi campus by making full use of the school's building floor and vacant land area. 1.1 Industry development and market application prospects Photovoltaic application scenarios cover almost all industries, and new energy is the inevitable trend of automotive energy development in the future. According to relevant data, as of the end of last year, the number of charging piles in the country has reached 450,000, an increase of 51% year-on-year. But it is still unable to meet the changing needs of this large number of electric vehicles in my country [1] . Although the driving range of the vehicle has increased and the problems in the charging link have been alleviated to a certain extent, the problem of charging difficulties still exists. With the continuous improvement of photovoltaic and energy storage technology and the maturity of the environment, the "photovoltaic, energy storage, charging pile" will be formed into a grid-connected and off-grid energy storage system, photovoltaic off-grid system, micro-grid energy storage system, and photovoltaic grid-connected a microgrid system that combines multiple complementary energy power generation with energy storage and other systems [2] . It is very suitable for use in places where photovoltaics have been self-generated for self-use but cannot be connected to the grid, peak electricity prices
