Embodiment Construction
[0052] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0053] 1. The present invention proposes an energy storage-assisted wind power primary frequency modulation control method based on dynamic task coefficients, which includes the following steps:
[0054] 1) Divide the entire primary frequency modulation process into an inertial response phase and a primary frequency modulation phase with the maximum frequency deviation as the boundary;
[0055] 2) Depth control of energy storage output considering task coefficient;
[0056] 3) Depth control of energy storage output based on SOC and maximum frequency difference feedback.
[0057] The division method of the inertial response phase and the primary frequency modulation phase in the step 1) is as follows:
[0058] ① The inertial response stage is defined as: from the time when the frequency deviation crosses the frequency modulat...
