Embodiment Construction
[0037]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] Such as figure 1 As shown, the control method of the CPS standard-oriented automatic generation control unit provided by the present invention comprises the following steps:
[0039] In step S101, at the end of the current control cycle of the automatic generation control unit, the expected frequency deviation value and its function transformation are calculated to generate the expected frequency deviation in the future, and then calculate the correction component. The transformation function may be, but not limited to, a sign function, a threshold function, a linear function, and the like. ...

The invention discloses a method and system for controlling a CPS (Control Performance Standard) oriented automatic generation control unit. The method comprises the following steps of: calculating the expected value of frequency deviation at the end of the current control period of the automatic generation control unit, generating future frequency deviation expectation after the functional transformation of the expected value, and further calculating corrected component; and collecting control deviation in the calculation region, calculating the total regulation amount of the automatic generation control unit in next control period by combining the corrected component, and sending the total regulation amount to the automatic generation control unit. Because when the method for controlling the CPS (Control Performance Standard) oriented automatic generation control unit provided by the invention performs regulation control on the next control period of the automatic generation control unit, the total power regulation amount is calculated based on future frequency deviation expectation instead of instant frequency deviation and the integral component causing frequent motor regulation is discarded, the CPS index of the control region is increased. Meanwhile, the loss of the automatic generation control unit is reduced, resources are saved, and the energy saving effect is obvious.
Description
technical field [0001] The invention belongs to the technical field of power system control, and in particular relates to a control method and system for a CPS standard-oriented automatic generation control unit. Background technique [0002] Automatic Generation Control (AGC) is one of the important means to maintain power balance and ensure frequency quality in the power system, and the formulation of automatic generation control strategies needs to consider many factors, the most important of which is to assess the performance of regional control control performance evaluation criteria. [0003] Control performance evaluation standards mainly include: A standard and CPS standard. Due to many recognized defects, the widely used A standard has been eliminated. At present, the CPS standard is used for control performance evaluation in major regional power grids. In order to adapt to the CPS standard, the AGC strategy of the original A standard needs to be improved. [0004...
