Enterprise electricity utilization carbon emission accounting method and system coupled with dynamic carbon emission factors

Abstract

The invention provides an enterprise power utilization carbon emission accounting method and system coupled with a dynamic carbon emission factor, and belongs to the technical field of enterprise power utilization carbon emission, and the method comprises the steps: obtaining original time-sharing electric quantity data of an enterprise power consumer and dynamic carbon emission factor data provided by a power grid, and carrying out the preprocessing of the obtained data; performing time-sharing electric quantity accounting on the preprocessed data based on a difference algorithm, calculating actual electric power every 15 minutes point by point, and generating electric quantity time sequence data; calculating dynamic factor carbon emission based on the electric quantity time sequence data; calculating fixed factor carbon emission based on the electric quantity time sequence data; synchronously aligning the generated time sequence data of the dynamic factor carbon emission and the fixed factor carbon emission, and judging whether the day is a typical day or not; and if the day is a typical day, extracting key characteristic parameters of an electrical load curve form, a carbon emission intensity time sequence characteristic, a peak value appearance moment and duration time from the identified typical day sequence.
