Embodiment Construction
[0064] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0065] The present invention provides a two-stage scheduling wind-fire coordination control method for sharing the delivery section in different regions, such as figure 1 As shown, the method includes the following steps:
[0066] (1) In the AGC (Automatic Generation Control, AGC) application of the first dispatch center, a section control area 1 is established for the sub-regional shared section. Although the conventional thermal power units in the thermal power plant 11 perform active power control, the planning mode is used for power control; the first dispatch center in this embodiment may represent a branch dispatch center (referred to as sub-dispatch).
[0067] (2) In the second dispatching center AGC, a mixed control area 2 is established for the sub-area shared section, and the mixed control area is used for the second dispatch and regulation of the ...

The invention discloses a two-level dispatching air-fire coordination control method for sharing outgoing sections in sub-regions, aiming at the operation status of the conventional thermal power unit with sub-division and provincial regulation and the new energy with provincial regulation and regulation belong to a certain control section. There is a certain deviation in the prediction of energy recently. In order to make full use of the transmission capacity of the section to deliver new capabilities, a two-level dispatching collaborative control structure and data interaction mode are established to deal with the overloaded and out-of-limit operation of the section, respectively. According to the operating status and the adjustment ability of the pipe unit, the coordinated control request is submitted to the first dispatcher, and finally through the coordinated control of the first dispatcher AGC and the second dispatcher AGC, under the premise of ensuring the safe and stable operation of the section, the section transmission capacity is fully utilized. , to improve the efficiency of energy delivery.
Description
technical field [0001] The invention relates to a wind-fire coordinated control method, in particular to a two-stage scheduling wind-fire coordinated control method for sharing delivery sections in different regions. Background technique [0002] Wind power generation is currently a renewable energy power generation method with relatively mature technology and good economic benefits besides hydropower. After the grid-connected operation of large-scale wind power, the impact of the randomness, volatility and intermittent characteristics of wind power on the safe and stable operation of the power grid has gradually emerged. With the start of construction of several 10-million-kilowatt-scale wind power bases in China, it is gradually becoming more difficult for the power grid to fully absorb wind power under the premise of ensuring safe and stable operation and active power control performance. high demands. [0003] According to the requirements of the national new energy po...
