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 incremen

specific Embodiment

[0148] In this embodiment, the adjustable generators are divided into two categories: adjustable and boostable generators and adjustable non-scalable generators. Adjustable and increaseable generator means that the output power of the new energy generator under the control of the control command does not reach the MPPT power, and it also has the ability to increase the output power upwards. Adjustable non-increasable generator means that the output power of the new energy generator under the control of the control command has reached the MPPT power, that is, the planned power generation corresponding to the control command is greater than the current MPPT power value, and there is no ability to increase the output power for the time being. . The distinction between adjustable and boostable generators and adjustable and non-scalable generators is temporary and dynamic. As the external weather environment changes, they can be converted into each other.

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.
