Energy internet system construction method and equipment based on cloud energy storage terminal

Abstract

A method and device for constructing an energy internet system based on a cloud energy storage terminal. Based on the cloud energy storage terminal, an energy Internet system composed of a control center and several cloud energy storage terminals is constructed. The control center communicates with the cloud energy storage terminal one-to-one, analyzes the load of the power grid, and controls the charging control system in the cloud energy storage terminal. And its adjustable input reactance and the inverter system and its output reactance adjustable circuit are regulated, and then the power supply and load of the power grid are regulated. The control center includes an industrial control computer, the electrical parameter acquisition module of the control center, and the power line carrier communication module of the control center are respectively connected to the three-phase power line, and several cloud energy storage terminals are respectively connected to the A phase, B phase and C phase of the three-phase power line, forming a system based on Energy interconnection network of cloud energy storage terminals. The invention solves the current situation of uncontrollable energy supply in the existing new energy technology, eliminates transmission loss, reduces energy loss and grid backup power scale, and has broad application prospects.

Description

1. Technical field [0001] The invention belongs to the field of electric power and relates to energy storage, in particular to the construction and equipment of an energy Internet system of a cloud energy storage terminal. 2. Background technology [0002] Today, the global climate problem threatens the human living environment. Modern lifestyles and production methods must rely on energy, and the use or production of energy must emit carbon dioxide. The greenhouse effect caused by carbon dioxide is an important reason for the rise in global temperature. The supply of global energy mainly depends on electric energy, and the production of electric energy mostly relies on the combustion of coal or oil, and the combustion process will produce a large amount of carbon dioxide. In order to reduce the carbon dioxide produced in the process of electric energy production, the world vigorously promotes clean energy production methods. At present, the main clean energy production met...
