It completes that updated energy storage device operation information is uploaded to layer distributed controller after entire coordinated allocation process
Carry out Partial controll next time.
5th step, the exploitation of energy storage energy routing controller software；
Wherein, the exploitation of energy storage energy routing controller software includes the design of algorithm groupware and setting for communication protocol plug-ins
Meter；The design of algorithm groupware, including initialization function, filter function function, BMS acquisition of information function, priority orders table
Tuning function and energy storage device power target value partition function；
Wherein, the design of communication protocol plug-ins including the ModBus protocol plug-in design communicated with BMS and PCS and divides
The IEC 60870-5-104 protocol plug-in design of layer distribution control unit communication.
Distributive mixing energy storage power is controlled using high-pass filtering, the power distribution expression formula on frequency domain are as follows:
Wherein, TfFor time constant filter, P is power, PL(s) low-pass filtering active-power P is indicatedLLaplace transformation,
PH(s) high-pass filtering active-power P is indicatedHLaplace transformation, determine the cutoff frequency of high low-pass filtering, that is, determine vibration frequency
Line of demarcation second grade is often set to minute grade according to the charge and discharge electric frequency of two class energy storage.
According to such distribution principle it is found that high-pass filtering PHAs the variation of power P is in high-frequency fluctuation, and low-pass filtering
PLThe remaining slowly varying part P is then undertaken, the distribution of power to energy type energy storage and power-type energy storage is achieved in.
The optimization energy storage coordinated control efficiency, the control target for needing to solve to be issued by layer distributed controller every time
The variation of SOC state still results in the minimum energy storage of period SOC and becomes not least after a period of time of charging when value
SOC value so as to cause at this moment if there is discharge target when again start electric discharge the problem of.It is led in order to avoid this charge and discharge are imperfect
The case where charge and discharge circulation life of the very big reduction energy storage caused, it is set as only in the SOC value for monitoring some energy storage device
Reach setting threshold value when just change one sub-priority, which is moved to the end of priority sequence, and be set as not followed by
It is continuous, it can only opposite direction charge and discharge.Finally consume in addition to charge and discharge target value one is known according to such priority change rule
Outside a energy storage device, other devices can all undergo the circulation from extremely low electricity to high electricity.Due to charge and discharge target values with
Machine, therefore necessarily have the energy storage among priority sequence and can undergo charge and discharge back and forth, this is can not be by setting point
It is avoided with strategy, but is constantly carrying out circulation sliding since entire sequence is equivalent to when energy storage device reaches threshold value, because
The probability for the charge and discharge of small-power back and forth that this each energy storage device may be undergone is also roughly the same, therefore this strategy can guarantee and make
The overall performance service life for obtaining multiple energy storage devices can reach maximum, and the control plan of charge and discharge sequence will not be determined as single priority
Slightly equally necessarily cause the charge and discharge cycles of each energy storage device unequal and may be all in the severe operation of charge and discharge back and forth
In operating condition, so that average life span substantially reduces, and replacing construction is different causes maintenance work cumbersome.
Obtain formulating the control strategy of energy storage energy routing controller, in the present embodiment, the specific control according to first three step
System strategy are as follows:
The target control power for receiving layer distributed controller first, according to battery variety label (lithium battery, super capacitor
Deng) by the high fdrequency component demand of variation be transmitted to super capacitor etc. can quick charge and discharge, service life long energy storage device will be slowly varying
Low frequency component demand be transmitted to that the energy storage such as lithium battery are more, but the energy storage device that cycle life is short；Next needs to carry out energy storage
The protection for filling over-discharge, since super-charge super-discharge can cause very big injury to energy storage device, it is therefore desirable to each equipment is arranged anti-
Only super-charge super-discharge SOC protects threshold value.Then the preferential charge and discharge priority orders of energy storage device are established according to each energy storage SOC state
Table preferentially discharges to energy storage forward in the priority orders table, and energy storage preferentially low to priority is charged,
The power output that full hair (priority method) determines each energy storage is inputted according to maximum output, which, which only works as, has
Energy storage device reach charge and discharge threshold value when just change, will arrival overcharge threshold value energy storage device move to priority orders table most before,
The energy storage device for reaching over-discharge threshold value is moved into priority orders table finally, the device setting for needing to be up to threshold value simultaneously can not
Continue to charge or can not continue the flag bit that discharges, continuation charge or discharge are not involved in power allocation procedure later, and only
Carry out reverse procedure.When carrying out high frequency and smooth power distribution respectively according to priority orders table, if there is surplus power can not
When consumption, needs for dump power to be given to a further type of energy storage and be placed on tail portion and continue assigning process.
It completes updated energy storage device operation information, such as voltage, SOC state, power after entire coordinated allocation process
The information such as out-of-limit are uploaded to the decision that layer distributed controller carries out Partial controll next time.The flow chart of control is as shown in Figure 1.
In the present embodiment, initialization function uses initplug () function, has mainly used the offer of C2 embedded platform
Real-time table log in, operation interface is read out the configuration information of device in device table.Filter function function uses filter
() function, the relevant interface that the main reading real-time database telemetering scale provided using C2 embedded platform is read, with acquisition point
