Embodiment Construction
[0049] In order to better understand the present invention, the technical solutions of the present invention are further described below with reference to the accompanying drawings.
[0050] Use a single-unit two-zone system for modeling and simulation, and the system model block diagram is as followsfigure 1 where sub-region i is the wind power disturbance region and region j is the non-disturbed region. In order to simplify the calculation, centralized parameters are used for simulation analysis; such as figure 1 shown, B i , B j is the frequency deviation coefficient; a i , b i Assign coefficients to ACE; R i , R j is the adjustment coefficient; ACE i , ACE j is the regional control deviation; T g,i , T g,j is the governor time constant; T t,i , T t,j is the time constant of the steam turbine; H i , H j is the inertia time constant of the system; D i , D j is the system load damping constant; ΔP g,i , ΔP g,j is the output power of the governor; ΔP t,i , ΔP ...
