Calculation Principle

1

Reserve capacity

Max{5% of the maximum load, maximum capacity of the single unit within the network};

Predictive wind power deduce 20% installed capacity to participate on power balance

2

Conventional power supply mode

Minimum period for the unit start and stop is once a week

3

Maximum and minimum technical output of the thermal power units

Minimum operating mode provided by Electric Supervision Bureau

4

Load data

The same as the previous year

5

Constraint conditions of hydropower units in electricity power balance

Maximum and minimum technical output is determined according to the actual operation requirements; utilization hours is in accordance with average water year or nearly three years

6

Annual renewable energy utilization hours

According to the average level of the past three years to calculate

7

Renewable energy time sequence

Renewable energy time sequence recovered from actual output data of the previous year

8

Transmission line principle

Transmission line mode is fixed, arranged respectively in different months
