Between energy difference.
Compensation device of the present invention can several parallel connections, the ac bus of access demand response energy consumption equipment side；
To meet the requirement of different capacity.Automatic network-building between each compensation device, receive the instruction of demand response regulation and control terminal, according to every
The surplus of energy-storage units in platform compensation device, determine respective discharge capacity or charge volume.In Regional Energy overall well-to-do period,
As wind energy or luminous energy are more abundant, the not high spring and autumn of total load, compensation device can also be by the pattern of peak-trough electricity energy-accumulating power station
Work, to make full use of equipment, allow maximum revenue.
Referring to Fig. 2, the structural representation of demand response compensation device in the present invention, demand response compensation device bag are shown
Include two way convertor (PCS), battery management unit (BMS), energy-storage battery group, control unit, detection metering units and communication unit
Member, wherein, PCS is responsible for energy conversion, both can with battery to grid transmission, can also power network charged to battery.BMS is responsible for detection
The key messages such as the electric current of every group of monomer of battery pack, voltage, temperature, and control unit is sent the data to, while in charge/discharge
When ensure that every group of monomer flows, pressed.Energy-storage battery group must be low capacity, the motive-power battery of high-discharge-rate, with lithium from
Based on sub- battery.General stored energy capacitance selection is discharged 20~30 minutes in full power.Detection metering units effect is detection power consumption
The parameters such as the real-time voltage of equipment, electric current, power, while measure electricity.Communication unit is responsible for receiving, sends data to demand sound
Should regulate and control terminal, and with other compensation device group-net communications.Control unit collects various data messages, the Working mould of decision systems
The parameters such as formula, watt level.
The demand response compensation device designed using the present invention, can be operated in different mode of operations, various to be applicable
Different application scenarios.
1st, compensation model
When demand response regulation and control terminal receives the startup order that main station system is sent, energy consumption equipment and compensation device are same
Shi Qidong.The energy consumption equipment power at metering units record current time, the reduction that control unit instructs according to main website are detected first
Value and the time for completing response, current time PCS compensation power is calculated, and start to discharge to ac bus.Set in power consumption
During standby progressively regulation, PCS compensation power is also accordingly made adjustment.When equipment completion regulation, or the deadline is reached,
Or when receiving the termination signal of main website transmission, compensation equipment stops electric discharge.
2nd, rectification mode
After compensation model terminates, just into rectification mode.Now PCS charges from ac bus power taking to energy-storage battery.Root
According to the plan of main website, there can be two kinds of rectification modes.As main website determines capacity may be arranged to regulate and control in following 8 hours, then mend
System is repaid to charge using 1/4C~1/6C；As main website did not arranged capacity to regulate and control in following 8 hours, then compensation system according to when
Between, at peak, electricity choosing period of time is charged using 1/15~1/20C, is charged in the paddy electricity period using 1C~1/4C.
3rd, backup mode
If power distribution network catastrophic failure, compensation device can quickly identify and be switched to backup mode.Now first confirm that automatic
Shearing device has disconnected ac bus, and PCS carries out DC/AC inversions afterwards, is discharged to the demand response electrical equipment of the access point,
Drop power regulating signals are sent to it simultaneously.After power system restoration is normal, backup mode, and incoming transport bus again are exited.
As energy-storage battery group has consumed more than 90%, when power network does not recover yet, then sent to the demand response electrical equipment of the access point
Soft-off signal, power-off suddenly is avoided to cause bigger loss.
4th, energy storage pattern
In Regional Energy overall well-to-do period, main station system, which sends instruction, can make compensation device be operated in energy-accumulating power station mould
Formula.Now, compensation device can use as a small-sized energy-accumulating power station., can according to the short-term scene of main website and load prediction
The generation schedule of whole plant area's whole day each micro battery of 24 hours, load electricity consumption plan are arranged with reasonable plan ahead, energy storage is filled
Electric discharge plan, generation schedule and power demand is set to reach balance generally.It is small that compensation device can be arranged in load power consumption,
Charged when electricity price is low；It is big in load power consumption, discharged when electricity price is high.Realize that paddy electricity peak is used, reduce electric cost.Compensation system has
The charging interval of body, charge power, discharge time, discharge power are planned as a whole to determine by main website.
5th, communication modes
To realize the purpose of main website carries out automatic demand response control, operational monitoring to user power utilization equipment, main website needs
By automatic demand response terminal, real-time information communication, transmission regulation are carried out with compensation device and the main electrical equipment of user
Instruction, real-time collecting device running status, environment parameter and with can situation.Communication modes mainly include following several classes：
Sent in live real time data：Support by DLT645, MODBUS, OPC and BACnet agreement collecting device energy and
Running status, and uniformly switch to IEC60870-5-104 teletransmission stipulations, sent in remote signalling amount displacement in real time, on remote measurement quantitative change bit timing
Send, meet to monitor and call together in real time to survey adjustable requirement.
Demand response instruction issuing：Demand response control instruction, using compatible GDW376.1 communications protocol, can and electricity consumption
Information acquisition system slitless connection.
Control instruction forwards：Demand response instruction translation is the control to equipment according to preset control strategy by terminal
Instruction, and can be communicated by MODBUS agreements with device controller.It can also be led to by OPC or BACnet with BAS system
News, then pass through BAS system control device state.
Referring to Fig. 3, a kind of FB(flow block) of demand response method for energy internet in the present invention is shown, including
Following steps：
Step S1：In mechanical floor power demand side, at least one demand response compensation device is set；
Step S2：Demand response regulates and controls terminal and filled according to regulation and control demand to demand response electrical equipment and demand response compensation
Put transmission regulating command；
Step S3：Demand response compensation device carries out charge or discharge according to regulating command, to perform use in electrical equipment
To the energy difference between the regulation of power network compensation power network target and electrical equipment practical adjustments during electricity regulation.
Using above-mentioned technical proposal, the present invention in mechanical floor power demand side by setting demand response compensation device to participate in
Power grid regulation compensate, so as to allow possess be unsatisfactory on regulating power but regulating time require electrical equipment can participate in the energy
In the automatic demand response system of internet.This equipment range of choice for making it possible to participate in automatic demand response is greatly widened,
Also the ability of regulation and control of energy internet is made be strengthened.
