The invention discloses a determination method of an 8760h load curve. Comprising the steps of collecting historical data and planning data, calculating a daily load curve of each month of a design level year, further calculating to obtain a load adjustment coefficient, calculating a monthly load curve of each month of the design level year, calculating a monthly load curve of each month, and calculating the maximum load of the design level year according to the maximum load and the annual load curve of the design level year. According to a typical daily load curve and a monthly load curve of a design level year, a 8760h load curve of the design level year is deduced. The annual maximum load of the 8760h load curve is consistent with a design value, the annual electricity consumption is consistent with the design value, the monthly maximum load is consistent with the design value, the daily load curve shape is consistent with the design value, the power demand prediction related results ...
