New energy power station equalization group control power generation control method and device

Abstract

The invention discloses a new energy power station equalization group control power generation control method and device. The method comprises the steps of determining an adjustable and increasable power generator set and an adjustable and non-increasable power generator set in an adjustable power generator set according to the real-time active power information of each power generator of a new energy power station when an AGC scheduling command is received, determining an active output adjustment mode of the adjustable power generator set according to the planned output active power corresponding to the AGC scheduling command, the adjustable and increasable power generator set information and the adjustable and non-increasable power generator set information, and adjusting the adjustableand increasable power generator and the adjustable and non-increasable power generator according to the determined adjustment mode. According to the method, the problem that the actual output may notreach the corresponding planned value due to the traditional equalization group control adjustment method is avoided, and the problem that the excessive power generation capacity exceeds the standardwhich cannot be solved by the traditional equalization group control adjustment method under the condition of unstable weather change can also be solved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an AGC equal-divided group control adjustment method and device for a new energy power station. Background technique [0002] Modern life has long been inseparable from electricity. In the first quarter of 2020, my country's total power generation reached 1.1 trillion kWh, of which fossil energy accounted for 76%, and wind energy and solar energy accounted for 6.5%. Traditional petrochemical energy is facing resource depletion. In addition, environmental pollution is also an important issue. The energy structure that relies too much on fossil fuels has caused great negative impacts on the environment, economy and society in my country. Therefore, vigorously developing renewable energy such as wind energy and solar energy is an inevitable choice to ensure the security of my country's energy supply and sustainable development. [0003] The output active power of wind power...

Problems solved by technology

[0009] In the traditional equal-sharing group control adjustment method, when it is necessary to increase the power generation, it is possible to reverse the adjustment of the generators that originally had a large output (that is, reduce the current output), and the generators that originally had a small output need to share more incremental power generation. , leading to an increase in the possibility of failing to meet the sharing requirements; when it is necessary to reduce the power generation, it is possible that the generator with a small output may need to increase the power generation instead, so that the actual output may not reach the corresponding planned value
