The basic thought of the present embodiment is to initially set up route digestion capability model, is meeting node voltage and branch power
Deng operation constraint condition under, fully consider load fluctuation and the distribution situation of distributed generation unit in the line, seek single
The maximum distribution formula generator unit installed capacity that medium-voltage line can access；Secondly traditional forward-backward sweep method is improved,
Preferably to handle the distribution power system load flow calculation containing distributed generation unit；Again, connecing by iterative calculation energy-storage system
Enter capacity and position.
Based on above-mentioned thought, the present invention proposes a kind of addressing constant volume configuration method of distributed energy storage system, such as Fig. 1 institute
Show, comprising the following steps:
S1: establishing route digestion capability model, and seeks obtaining single line and can connect by route digestion capability model
The maximum installed capacity of the distributed generation unit entered.
Medium voltage distribution network single line distributed generation unit digestion capability research, can be described as meeting node voltage
Under the operation constraint condition such as branch power, load fluctuation and the distribution feelings of distributed generation unit in the line are fully considered
Condition seeks the maximum distribution formula generator unit installed capacity that single medium-voltage line can access.
Constraint condition is main: power-balance constraint, node voltage constraint, the constraint of substation bus bar voltage, capacity of trunk are about
Beam etc. passes through the maximum for the distributed generation unit that route digestion capability model is calculated based on above-mentioned constraint condition is considered
Installed capacity is more accurate.

S2: after distributed generation unit access, the active and reactive trend and route each node of each node of route are calculated
Voltage deviation；
The line loss in electric current and route in order to more effectively calculate the voltage of each point in route, each branch, power distribution network tide
Stream calculation mainly uses forward-backward sweep method.Back substitution tidal current computing method is pushed forward using power distribution network bus bar side power supply point as root node,
It is divided into being pushed forward with back substitution two parts and calculates.
However, traditional forward-backward sweep method cannot handle the distribution power flow meter containing distributed generation unit well
It calculates, key problem is that traditional forward-backward sweep method cannot handle PV type node.It is active due to PV type distributed generation unit
For steady state value, as long as thus reactive power size can be found out, PV type distributed generation unit can be converted to and be pushed forward back substitution
The PQ type node that method can be handled.
In order to handle PV type distributed generation unit node Q problem well, need to be subject on traditional forward-backward sweep method
It improves, i.e., the idle initial value of PV type distributed generation unit is determined based on idle methodology: first being marked PV type node type
Know；Then determine that root node, the load or burden without work between PV type node are shared out equally by the two, and PV type node to endpoint node it
Between load or burden without work by PV type node distributed generation unit provide.If PV type distributed generation unit grid entry point is in spoke
It penetrates between a plurality of branch of network, preferentially chooses the maximum branch of endpoint node load or burden without work.Specific calculating process is as follows:

Distributed generation unit it is idle, substituted by the limits value shared, calculate the active and reactive trend distribution of route；
(3) back substitution method seeks each node voltage:
It is piecewise by known beginning node voltage and the beginning power terminad node being calculated since beginning node
It calculates, by formula:The voltage deviation for calculating route, subtracts this voltage by node i voltage
Offset obtains the voltage of ij sections of j end nodes of route.
(4) convergence criterion used is calculated: | △ Ui| < ε 1, | △ Pi|<ε2；
Wherein △ UiIndicate step (2) and (3) one cycle voltage change, that is, stop calculating condition be | △ Ui|=
Ui-Ui-1< ε 1, ε 1 is taken as 0.001；△PiIndicate the node power variation of step (2) and (3) one cycle, ε 2 is taken as 0.001；
(5) above-mentioned (2)~(4) step is repeated, until whole convergences.
