Description
Technical Field
The invention belongs to the field of wind power systems, and particularly relates to a wind turbine generator and energy storage coordinated frequency modulation control method and system.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
With the rapid development of wind power, the specific gravity of the wind power in the system is gradually increased, the safe and stable operation of the system is seriously challenged, and the improvement of the active supporting capability of the wind power system becomes the key of the sustainable development of the wind power. However, since wind power is affected by fluctuation of wind resources, wind power output has intermittency and volatility, and it is difficult to ensure reliable energy input. The inventor finds that although the conventional wind power comprehensive inertia or primary frequency modulation control strategy taking rotor kinetic energy utilization as a core can provide a short-term active support according to frequency differentiation and deviation, the problem of secondary frequency drop is brought, even larger load impact is caused, and both the system frequency recovery and the unit load are adversely affected.
Disclosure of Invention
In order to solve the technical problems in the background art, the invention provides a wind turbine generator and energy storage coordinated frequency modulation control method and system, which can realize stable wind power support and avoid load impact in the process of secondary frequency drop and recovery of the system.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a wind turbine generator and an energy storage coordinated frequency modulation control method.
A wind turbine generator and energy storage coordinated frequency modulation control method comprises the following steps:
releasing rotor kinetic energy of the wind turbine generator, and adjusting active power of stored energy based on a difference value between required support power and a wind turbine generator output reference value to achieve stabilization of active power fluctuation during support;
adjusting the output power of the wind turbine generator to be reduced to an initial value level, wherein the energy storage output is zero so as to reduce the impact on the wind turbine generator and the energy storage;
and adjusting the reference power of the wind turbine generator to an optimal power curve, recovering the rotating speed, and filling up the power depression of the output power of the stored energy so as to realize stable transition after frequency response and avoid secondary frequency drop.
In the process of adjusting the active power of the stored energy, when the difference value between the required support power and the output reference value of the wind turbine generator is smaller than the maximum power of the stored energy, the stored energy makes up the power difference.
Further, in the process of adjusting the active power of the stored energy, when the difference value between the required support power and the output reference value of the wind turbine generator exceeds the maximum power of the stored energy, the stored energy is output according to the maximum power.
Further, the rotor kinetic energy of the wind turbine is released through a frequency control loop at the outer loop of the wind turbine power.
Further, in the process of adjusting the output power of the wind turbine generator to be reduced to the initial value level, the output power of the wind turbine generator is reduced to the initial value level according to a set time function.
Further, in the process of adjusting the reference power of the wind turbine generator to the optimal power curve, the reference power of the wind turbine generator is restored to the optimal power curve according to the function of the set rotating speed.
The second aspect of the invention provides a wind turbine generator and energy storage coordinated frequency modulation control system.

the supporting module is used for releasing the rotor kinetic energy of the wind turbine generator and adjusting the active power of the stored energy based on the difference value between the required supporting power and the output reference value of the wind turbine generator so as to realize the stabilization of the active power fluctuation during the supporting period;
the transition module is used for adjusting the output power of the wind turbine generator to be reduced to an initial value level, and the energy storage output is zero so as to reduce the impact on the wind turbine generator and the energy storage;
and the recovery module is used for adjusting the reference power of the wind turbine generator to an optimal power curve, recovering the rotating speed and filling the power depression of the output power of the stored energy so as to realize stable transition after frequency response and avoid secondary frequency drop.

A computer device comprises a memory, a processor and a computer program which is stored on the memory and can run on the processor, wherein the processor executes the program to realize the steps of the wind turbine generator and energy storage coordinated frequency modulation control method.
Compared with the prior art, the invention has the beneficial effects that:
the wind storage combined frequency modulation is divided into three processes, namely a support period, a transition period and a recovery period, wherein a wind turbine generator releases rotor kinetic energy in the support period, and an energy storage power supply stabilizes power fluctuation to realize stable and constant support; the wind turbine generator set in the transition period gradually reduces the output power to an initial value along a given reference value (a function related to time), so that the load of the wind turbine generator set and the impact on a system can be reduced simultaneously; in the recovery period, the wind turbine generator recovers to an optimal power curve along a given reference value (a function related to the rotating speed), the energy storage output active power compensates the power depression, and the frequency secondary falling is avoided.
