Household energy optimization system and method based on multi-user networking shared energy storage

Abstract

The invention discloses a household energy optimization system and method based on multi-user networking shared energy storage, and the system comprises a centralized shared energy storage module which consists of a power electronic device and a group of single storage batteries, and is used for the power utilization and energy storage of a plurality of household users; the internal power supply module which is formed by networking a plurality of home users and is used for direct energy circulation among different users; the energy optimization module which is used for investing, maintaining and managing the centralized shared energy storage module, maintaining the power balance of the internal power supply module and providing power utilization and energy storage optimization services forusers; the home user side module which is used for arranging a next-day home appliance power utilization plan and carrying out information exchange and online payment with the energy optimization module; the external power supply module which is communicated with external power supply equipment and used for supplying power to the whole system, energy storage equipment originally scattered in a user home is changed into centralized shared energy storage system coordination optimization, and compared with original scattered energy storage equipment, the total energy storage capacity is reduced,and the energy storage space utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of home energy optimization, in particular to a home energy optimization system and method based on multi-user networking and shared energy storage. Background technique [0002] In recent years, the demand for energy has expanded rapidly, the supply of fossil energy represented by petroleum is in short supply, and the cost is rising day by day. The situation of global warming is very serious. Energy conservation and emission reduction have become an urgent task for the international community today. As the scale of the global power industry grows year by year, the electrification of energy and terminal energy consumption is an inevitable trend of historical development and social development. Promoting the development of renewable energy can effectively solve the increasingly severe energy and environmental problems. It is an inevitable trend that renewable energy will replace traditional energy (such as co...

AI Technical Summary

Problems solved by technology

The traditional microgrid energy storage method has a fixed energy storage capacity and cannot adapt to seasonal changes in renewable energy generation and household electricity consumption

In addition, different users have differences in energy storage space and time due to different electricity consumption habits. From the perspective of the entire energy storage device, there is obviously a waste of energy storage space

The traditional way of selling electricity directly to the grid does not take into account the impact of surplus electricity directly connected to the grid on the power quality of the grid, unnecessary power loss caused by AC-DC conversion, and uneconomical power consumption.
