Abstract

The invention discloses a method and a system for controlling system energy efficiency. The system comprises a plurality of energy efficiency controllers and an energy efficiency matching station, wherein each energy efficiency controller is used for monitoring and acquiring energy information of an energy production link, an energy application link, an energy regeneration link and an energy storage link; energy conversion, flow and storage of the energy production link, the energy application link, the energy regeneration link and the energy storage link are controlled according to control information from the energy efficiency matching station; and the energy efficiency matching station is used for receiving energy information from the energy efficiency controllers, performing global optimization control on the energy cycle process of the energy production link, the energy application link, the energy regeneration link and the energy storage link based on an energy model and transmitting corresponding control information to the energy efficiency controllers.

Description

technical field [0001] The invention relates to energy technology, in particular to a system energy efficiency control method and a control system. Background technique [0002] With the development of modern industrial society, the natural resources endowed by nature to human beings are consumed in large quantities. Global oil reserves will be depleted around 2050; global natural gas reserves are estimated to be depleted around 2050; global coal reserves can be supplied for 169 years. The energy issue has become a fundamental issue for countries all over the world to seize the current period of international strategic opportunities. [0003] A serious consequence of the development of the world relying on fossil energy for more than half a century is the deteriorating global climate and environment. At present, climate change has become a strong constraint on global economic development, and environmental issues have become the most serious challenge to global sustainable...
