Number | Boundary Condition | 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 |
