Frequency regulation reserve optimization of wind-PV-storage power station considering online regulation contribution
The frequency regulation reserve setting of wind-PV-storage power stations is crucial.However
the existing grid codes set up the station reserve in a static manner
where the synchronous generator characteristics and frequency-step disturbance scenario are considered.Thus
the advantages of flexible regulation of renewable generations are wasted
resulting in excessive curtailment of wind and solar resources.In this study
a method for optimizing the frequency regulation reserve of wind PV storage power stations was developed.Moreover
a station frequency regulation model was constructed
considering the field dynamic response and the coupling between the station and system frequency dynamics.Furthermore
a method for the online evaluation of the station frequency regulation was proposed based on the benchmark governor fitting.This method helps in overcoming the capacity-based reserve static setting.Finally
an optimization model was developed
along with the proposal of the linearized solving algorithm.The field data from the JH4#station in China’s MX power grid was considered for validation.The proposed method achieves a 24.77%increase in the station income while ensuring the system frequency stability when compared with the grid code-based method.
