Research on the contribution of regional Energy Internet emission reduction considering time-of-use tariff.

Energy Internet is expected to solve the problem of environmental pollution. This paper first analyzes the emission reduction mechanism of the time-of-use tariff on the regional Energy Internet, and then establishes a calculation model of regional Energy Internet emission reduction considering time-of-use tariff. Finally, a small-scale regional Energy Internet is simulated and calculated, and it is found that the carbon emission under the time-of-use tariff is reduced by 0.95% and the cost is reduced by 0.28%compared with that under the fixed electricity price. The results show that the system operation cost and pollutant emissions are lower under time-of-use tariff, and time-of-use tariff is more conducive to emission reduction. Moreover, it is also found that when the time-of-use tariff fluctuation ratio is less than 1, and the peak-to-valley electricity price ratio is between 2-3, the energy conservation and emission reduction is better, which provides a basis for the formulation of green electricity price. The innovations of this paper mainly include: 1) Research from a new perspective that time-of-use tariff affect the demand side and thus the supply side. 2) Establish a calculation model of regional Energy Internet emission reductions under time-of-use tariff. 3) Study the peak-to-valley electricity price ratio, the fluctuation ratio of time-of-use tariff, and the impact of the two on the carbon emissions of the regional Energy Internet. • A calculation model of Energy Internet emission reduction under time-of-use tariff. • The dynamic impact of time-of-use tariff on energy demand. • The relationship between time-of-use tariff and pollutant emissions. • Impacts of the peak-to-valley ratio and price fluctuation ratio on emissions.
