Embodiment 1
[0035] If the maximum load on a certain day is predicted to be 21 million kilowatts, in order to ensure the consumption of clean energy, the thermal power unit is usually started with one more unit on the basis of the minimum number of units required for the maximum DC power to ensure that any thermal power unit fails to trip After that, it will not affect the transmission power of DC. According to the requirements in Table 1, 19 thermal power units will be operated on that day, and the maximum DC transmission power can reach 4 million kilowatts.
[0036] If the actual load on that day exceeds the predicted load by 21.5 million kWh due to the high temperature, according to the requirements in Table 1, under this load level, when the minimum power-on of thermal power units in the load center is 19 units, the maximum power of DC transmission is only 3 million kilowatt. Therefore, it is necessary to reduce the DC transmission power from 4 million kilowatts to 3 million kilowatts...
Embodiment 2
[0039] If the load level of the provincial power grid reaches 31 million kilowatts during a peak load period, the DC transmission power is 4 million kilowatts, and the power supply pressure is relatively high. According to Table 1, the minimum number of thermal power units in the load center is 24, and the minimum rotating reserve capacity is 3 million kilowatts.
[0040] The method for optimizing the minimum start-up mode of the present invention is used to obtain real-time operating state data and model parameters of the power grid to form online calculation data for the power grid, to check the minimum start-up mode of the power grid at this time, and to evaluate whether the minimum start-up mode obtained by off-line calculation has room for optimization. If the minimum spinning reserve capacity can be reduced from 3 million kilowatts to 2.7 million kilowatts at this time, the output of the limited unit can be increased by 300 thousand kilowatts, thereby increasing the power...
