Cloud energy storage terminal-based energy internet system construction method and apparatus

Abstract

The invention relates to a cloud energy storage terminal-based energy internet system construction method and apparatus. An energy internet system composed of a control center and a plurality of cloud energy storage terminals is constructed based on cloud energy storage terminals; the control center is in one-to-one communication with the cloud energy storage terminals, analyzes the magnitude of the load of a power grid, regulates and controls charging control systems in the cloud energy storage terminals and adjustable input reactance circuits of the charging control systems as well as inversion systems and output reactance adjustable circuits of the inversion systems so as to regulate and control the power source and load of the power grid. The control center comprises an industrial control computer; a control center electric parameter acquisition module and a control center power line carrier communication module are connected with a three-phase power line; the A phase, B phase and C phase of the three-phase power line are respectively connected with a plurality of cloud energy storage terminals; and therefore, a cloud energy storage terminal-based energy internet can be formed. With the method and apparatus of the invention adopted, the current situation of incontrollable energy supply in existing new energy technologies can be avoided, transmission loss can be eliminated, energy loss and the scale of the emergency power source of the power grid can be decreased. The method and apparatus have a bright application prospect.

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...
