Multi-port power switch based on AC-DC hybrid distribution and utilization

Abstract

The invention provides a multi-port power switch based on AC-DC hybrid distribution and utilization. The power switch comprises an electrical physical layer and an electrical information layer, wherein the electrical physical layer is composed of a power electronics solid state module, a solid state module controller, a protection and drive module, a monitoring and sensing module, an internal power supply module, a power interface module and a power storage module, and the electrical information layer is composed of an intelligent control module, a communication module and an upper layer management and application module. The management of a unified grid-connection function of a distributed power supply in a power distribution network is achieved, a uniform DC and AC circuit is established, and uniform power quality control and uniform energy management are achieved.

Description

technical field [0001] The invention relates to a power switch, in particular to a multi-port power switch based on AC and DC hybrid power distribution. Background technique [0002] With the development of economy and society, the continuous growth of energy production and consumption, and the massive development and use of fossil energy have led to problems such as resource shortage, environmental pollution, climate warming, glacier melting, and sea level rise, which seriously threaten human survival and sustainability. Continuous development. With the continuous advancement of new industrialization, informatization, urbanization, and agricultural modernization, and the continuous improvement of people's living standards, energy consumption will continue to grow, and the pressure on energy demand will continue to increase. The world is currently facing triple challenges of "energy security", "environmental pollution" and "climate change". Large-scale configuration and hi...
