Embodiment 1
[0034] Embodiment 1: as attached figure 1 As shown, this embodiment discloses a photovoltaic power station active power distribution method based on the priority of the parity station, including:
[0035] Step S101, obtain the power dispatch command issued by the grid dispatcher, and determine whether it is greater than the total actual power of the photovoltaic field group;
[0036] Step S102, in response to that, according to the principle of preferential power generation of the parity station, the power scheduling command is assigned to the AGC module of each photovoltaic power station, and the AGC execution assignment result of the photovoltaic power station is issued to each photovoltaic power station;
[0037] Step S103, if the response is no, then according to the principle of priority power reduction for non-parity power stations, the power scheduling command is distributed to the AGC modules of each photovoltaic power station, and the AGC execution assignment results ...
Embodiment 2
[0039] Embodiment 2: as attached figure 2 As shown, this embodiment discloses a photovoltaic power station active power distribution method based on the priority of the parity station, including:
[0040] Step S201, obtain the power dispatch command issued by the grid dispatcher, and determine whether it is greater than the total actual power of the photovoltaic field group;
[0041] Step S202, in response to this, determine the pre-allocated value of the parity station, where the pre-allocated value is the sum of the power generation demand and the original power generated by the photovoltaic power station;
[0042] Step S203, select a parity station, and judge whether the pre-allocated value is greater than the power generation limit of the parity station;
[0043] Step S204, in response to this, determine whether the power generation demand exceeds the sum of the power generation margins of the parity stations;
[0044] Step S205, in response to this, adjust the generati...
Embodiment 3
[0048] Embodiment 3: as attached image 3 As shown, this embodiment discloses a photovoltaic power station active power distribution method based on the priority of the parity station, including:
[0049] Step S301, obtain the power dispatch command issued by the grid dispatcher, and determine whether it is greater than the total actual power of the photovoltaic field group;
[0050] Step S302, in response to that, according to the principle of preferential power generation of the parity station, the power scheduling command is assigned to the AGC module of each photovoltaic power station, and the AGC execution assignment result of the photovoltaic station is issued to each photovoltaic station;
[0051] Step S303, judging whether the curtailed power is greater than the sum of the actual power of non-parity stations;
[0052] Step S304, in response to this, set the power of the non-parity station to the lower limit, and allocate the remaining power-limiting tasks to the parit...
