Example one
As shown in fig. 1, an active emergency control method for new energy includes the following steps:
1) acquiring a reduced output control instruction, wherein the reduced output control instruction is an instruction which is issued when the power grid frequency deviation of a control area where the new energy equivalent unit is located is larger than a preset value and is determined according to power grid monitoring data;
2) and counting the lower adjusting capacity of each new energy station of the new energy equivalent unit according to the reduced output control instruction, performing emergency reduced output distribution according to the counting result, and sending the distribution result to each new energy station so as to perform power control.
In step 1), as shown in FIG. 2,
11) in the application of a provincial dispatching center (called provincial dispatching for short) AGC, a conventional load frequency control model of a control area is established first, and conventional load frequency control of an interconnected power grid is implemented, wherein the control target of the control area is to maintain the frequency of the power grid within a control range, or maintain the exchange power of the control area and other adjacent control areas to be a given plan value, or simultaneously meet the two control targets. Besides the conventional AGC function, a new energy active automatic control system is required to be deployed in provincial dispatching and is responsible for implementing active automatic control on new energy stations in a dispatching and managing range.
12) The unit of the provincial dispatching AGC control area comprises a conventional water-fire motor set and a new energy equivalent unit, wherein control real-time data of the conventional water-fire motor set is derived from conventional load frequency control, and control real-time data of the new energy equivalent unit is derived from a new energy active automatic control system.
