It is integrated according to the frequency difference of any power grid, determines any power grid Automatic Generation Control mode and calculate the district control deviation of power grid,
Execute power grid Automatic Generation Control.Since the control of direct current additional frequency can be first passed through, phase cross-power branch in emergency circumstances is provided
It helps, then by the Automatic Generation Control of each power grid, restores each mains frequency and dc power automatically under normal circumstances, thus logical
The cooperation of direct current additional frequency control and power grid Automatic Generation Control is crossed, it is respectively independent when each asynchronous power grid operates normally, promptly
In the case of mutually support, thus realize each power grid frequency coordination control.
Content based on the above embodiment, as a kind of alternative embodiment, the embodiment of the present invention is not to according to secondary power
And the dc power setting value of normal consistency plan, the mode of dc power setting value for determining any power grid to other power grids are made
It is specific to limit, including but not limited to calculated by following formula:
Pij=Pij0+ΔPij；
Wherein, PijIndicate that any power grid is dc power setting value of the power grid i up to other power grid j, Pij0It indicates normal to adjust
Spend the dc power setting value of plan, Δ PijIndicate secondary power.
Content based on the above embodiment, as a kind of alternative embodiment, according to secondary power and normal consistency plan
Dc power setting value, before determining any power grid to the dc power setting value of other power grids, further includes: according to default frequency
Difference on the frequency between rate dead zone and any power grid and other power grids, determines secondary power.
Using any power grid as power grid i, for other power grids are power grid j, the frequency of power grid i can use fiIt indicates, power grid j's
Frequency can use fjIt indicates.Frequency dead band can use εfIt indicates, εfIt is greater than 0.
Content based on the above embodiment, as a kind of alternative embodiment, the embodiment of the present invention is not to according to predeterminated frequency
Difference on the frequency between dead zone and any power grid and other power grids determines that the mode of secondary power specifically limits, including but unlimited
It is calculated in by following formula:

After the dc power setting value that power grid i to power grid j is calculated, it can be executed according to the dc power setting value straight
Flow additional frequency control.Specifically, according to above-mentioned control method, direct current both ends power grid frequency difference hour do not support mutually (namely |
fi-fj|≤εfWhen), then mutually supported when frequency difference is big (namely | fi-fj| > εfWhen), corresponding situation is that certain power grid occurs greatly
Power disturbance, the mains frequency deviation are more than threshold value, and adjacent power grid supports the power grid, function automatically according to frequency difference adjustment dc power
Rate disturbance quantity is shared in each power grid, makes full use of the Primary frequency control ability of each power grid, alleviates the frequency departure of disturbed power grid.
When it is implemented, dc power additional control is generally periodic control model, with certain control period (allusion quotation
Type such as 1 second), measurement both ends mains frequency simultaneously according to above two formula calculate secondary power.The difference of above two formula
It is that the type of frequency dead band is different, the first formula for calculating secondary power is to have step dead zone, the additional function of second of calculating
The formula of rate is no step dead zone, can be selected as needed.Frequency dead band εfIt can be adjusted according to power grid demand, representative value can
Take 0.1Hz.The parameter of proportional plus integral control needs to be adjusted according to power grid demand, can also be only with ratio control or integration control.
Content based on the above embodiment, as a kind of alternative embodiment, the embodiment of the present invention is not to according to any power grid
Frequency difference integral, the mode for the district control deviation for determining any power grid Automatic Generation Control mode and calculating power grid specifically limits

Area,Indicate the unbalanced power amount of power grid.When district control deviation is taken asWhen, power grid is certainly
Dynamic Generation Control mode is dominant eigenvalues frequency bias control mode, when district control deviation is taken as KiΔfiWhen, power grid is automatic
Generation Control mode is to determine frequency control model.
Specifically, under normal circumstances, power grid ACE is equal to unbalanced power amount.At this point, the control of power grid Automatic Generation Control
Mode is dominant eigenvalues frequency bias control mode.Specifically, power grid is inclined using dominant eigenvalues frequency when not disturbing
Poor control model, ACE 0 do not execute power grid Automatic Generation Control.The power grid ACE disturbed is not 0, then certainly by power grid
Dynamic Generation Control restores frequency, and disturbed mains frequency is restored to dead zone εfWithin after, dc power restore planned value, do not disturb
Dynamic mains frequency restores automatically.
If the power disturbance amount of disturbed power grid is very big, the regulating power of its Automatic Generation Control, disturbed power grid are had exceeded
Frequency cannot restore for a long time, dc power deviation exists for a long time, causes to be undisturbed mains frequency deviation and exists for a long time.
At this point, being undisturbed power grid frequency difference integrated valueIt is larger, it is greater than threshold epsilonftWhen, the power grid ACE not disturbed switchs to
KiΔfi, control model at this time switchs to determine frequency control model, power grid AGC movement recovery frequency, while providing to disturbed power grid
More power are supported.But since disturbed grid power disturbance quantity has been more than the regulating power of power grid Automatic Generation Control, frequency
Rate can not be restored, and dc power can not also restore planned value, then need dispatcher to intervene, and readjust grid operation mode.
