Yoke transposition operation, V are flow controller side voltage vector, For set of complex numbers, E be route (i,
K) quantity,For the diagonal entry of matrix W,For the off diagonal element of matrix W, For yikConjugate operation, yikFor the admittance parameter of route (i, k), N is power grid to be installed
The bus set of network, ΩiFor the node set of flow controller in electricity grid network to be installed, p is average sales rate of electricity, ThFor
Load annual utilization hours, f0Power delivery capabilities coefficient when not installing trend router for electricity grid network to be installed is maximum
The ratio of transmission power and basic transmission power, f (u, v) are that electricity grid network power delivery capabilities coefficient to be installed and decision become
The functional relation of amount,Whether determining for trend router is installed for each bus of electricity grid network to be installed
Plan variable, if ui=1 represents the installation trend router on bus i, u on the contraryi=0 does not install then,For
Whether route (i, k) installs flow controller, if vi,j=1 represents installation, on the contrary then do not install.
It is understood thatConnecting line of the route (i, k) between bus i and bus k herein
Road, For series electrical potential source voltage change ratio,For phase shifter no-load voltage ratio,
For route (i, k) close to the side bus i flow controller voltage,
The corresponding income of each bus is subtracted the installation cost in bus installation trend router by step 203, is obtained
To electricity grid network to be installed in the trend router of separately installed each bus corresponding profit.
Step 204, in all buses, determine the maximum bus of profit.
It should be noted that determining that the mode of the maximum bus of profit can be to describe in above-mentioned steps in the present embodiment
Content, certainly for calculation amount the considerations of, or: determine trend router on separately installed each bus first
Then income finds the bus of Income Maximum, then the corresponding income of the bus is subtracted to the installation of trend router on the bus
Cost thinks that the bus is the maximum bus of profit.
Step 205 judges whether the corresponding profit of the maximum bus of profit is greater than zero, if so, by the maximum mother of profit
Installation bus of the line as the trend router of electricity grid network to be installed.
It should be noted that when determining profit corresponding to the maximum bus of profit greater than 0, profit is maximum
Installation bus of the bus as the trend router of electricity grid network to be installed, if it is not, then illustrating to be not required to installation trend on the bus
It is maximum when income when router, keep the existing structure of electricity grid network to be installed constant.
The each flow controller for the trend router installed in step 206, installation bus of individually stopping transport, and really
Order solely stop transport each flow controller when income reduction amount and cost saving amounts.
It should be noted that after the installation addresses that step 205 determines trend router, also to installation in the present embodiment
The structure for the trend router installed on bus optimizes, the trend road installed on installation bus of individually stopping transport first
By each flow controller of device, and determine the income reduction amount and cost saving amounts when individually stopping transport each flow controller.
All flow controllers corresponding income reduction amounts and cost saving amounts in step 207, judgement installation bus
Size, and remove the flow controller that income reduction amount is less than cost saving amounts.
It should be noted that the flow controller that income reduction amount is less than cost saving amounts is considered It is not necessary to installation
Flow controller, then the flow controller that will install this type on bus in the trend router installed removes.
Step 208, the capacity that each flow controller in the first trend router is determined according to constant volume formula, the first tide
Stream router is the trend router installed after the trend router execution step 105 installed on bus.
It should be noted that obtaining the first tide after removing income reduction amount to be less than the flow controller of cost saving amounts
Stream router also carries out the capacity of each flow controller for the trend router installed on installation bus in the present embodiment
It calculates, wherein the constant volume formula used are as follows:
Wherein, SPFCFor the capacity of flow controller,For the reactive compensation amount of bus, SBFor benchmark capacity, S1p.uFor
The series connection capacity that series voltage introduces.
In the present embodiment, trend router is installed first at multiple buses of electricity grid network to be installed, is then counted respectively
The profit of electricity grid network to be installed when calculating the trend router of separately installed each bus, and benefit is determined in all buses
Moisten maximum bus, then judge whether profit corresponding to the maximum bus of profit is greater than zero, if so, profit is maximum
Bus installs bus as the trend router of electricity grid network to be installed, and the installation addresses of trend router have thus been determined,
Solves the technical issues of existing addressing for trend router is without correlative study.
