A power grid source-load matching evaluation method and system

Abstract

The application discloses a kind of power grid source-load matching evaluation method and system, applied to new energy technology field, including obtaining current power grid green electricity output data and electricity load data;Green electricity output data is analyzed in time sequence, and green electricity output curve is obtained, and electricity load data is analyzed in time sequence, and electricity load curve is obtained;Characteristic extraction is carried out to green electricity output curve, and source side characteristic parameter is obtained, and characteristic extraction is carried out to electricity load curve, and load side characteristic parameter is obtained;Based on source side characteristic parameter and load side characteristic parameter, determine three-dimensional matching degree index;Based on three-dimensional matching degree index, determine the source-load matching result of green electricity output curve and electricity load curve, and the source-load matching result is at least used to represent the green electricity consumption level of current power grid.The method of the application can accurately evaluate source-load matching result.
