Embodiment Construction

[0042] In the present invention, the fluctuating energy supply and demand ratio in the smart grid is used as the main parameter for the interaction between the communication base station and the power grid to improve energy efficiency, and the communication base station adjusts its own energy consumption according to the energy supply and demand ratio, so as to realize the maximum net income of the communication base station (power user) , that is, the difference between the amount of information transmitted and the energy consumed is the largest. When there is a surplus of grid energy, the ratio of energy supply and demand decreases, and the communication base station uses more energy to increase the maximum net income, so that the remaining energy of the grid can be used reasonably; when the grid energy is overdrawn, the energy supply and demand ratio increases, and the communication base station Increase in maximum net benefit in exchange for reduced energy consumption.

Abstract

Disclosed is an energy distribution method between a power grid and a cognition base station in mobile communication. The energy supply to demand ratio serves as the main parameter of interaction between an energy supply main body and the base station in the intelligent power grid, the goal is the maximum net earning, a cognition base station sub-channel and power optimization distribution model of a base station downlink OFDM system is built, step-by-step solution is carried out on the cognition base station sub-channel and power optimization distribution model to obtain a distribution scheme of communication base station resources, the difference between the amount of information emitted by the base station and the consumed energy is maximized, instant balance of supply and demand of electric energy is guaranteed, and the stability of the power grid is maintained. The energy supply to demand ratio is introduced into the cognition base station sub-channel and power optimization distribution model, the electricity resources supplied by the intelligent power grid are distributed reasonably and used efficiently, instant balance of supply and demand of electric energy is guaranteed, and the stability of the power grid is maintained.

Description

technical field [0001] The invention relates to a method for adjusting the energy consumption of a communication base station according to the energy supply-demand ratio, so as to realize the maximum energy efficiency ratio of the communication base station (power user), and belongs to the field of communication technology. Background technique [0002] With the popularization of smart mobile terminals, various high-speed data application services have grown rapidly, and the energy consumption of the communication industry has also increased at an alarming rate. According to reports, the energy consumption of the entire information and communication industry, including cellular networks, accounts for 2% of global carbon dioxide emissions. The energy consumption of mobile operators is the highest in the information and communication industry, and the growth rate of energy consumption of mobile networks far exceeds the average level of the entire industry. According to statis...
