With the increasing proportion of wind power in the power system

the frequency regulation ability of the system is deteriorating

which poses a great challenge to the frequency stability of the system. In view of the above problems

this paper proposes a control strategy of wind power participating in grid frequency regulation based on Hamilton method. First

based on the principle that the wind turbine participates in the system frequency response through the change of active power output

the system frequency response model including wind power is constructed. Then

according to the Hamilton system control theory

the above model is transformed into the standard form of the dissipative Hamilton system model

and the expected equilibrium point adaptively adjusted with the load disturbance is obtained by using the steady-state frequency deviation expression. Finally

combined with the current and expected state of the system

the energy matching equation is constructed by using the energy shaping method

so as to obtain the output feedback control rate. On this basis

the active power control rate of the wind turbine can be obtained by reverse derivation according to the system control variables. The wind power system is built by MATLAB/Simulink for simulation verification. The results show that the Hamilton method control strategy can effectively improve the frequency response characteristics of the system as well as the frequency stability of the system.
