Island intelligent electric power utilization system with micro-capacitance sensor control centre when interacting, order by received information on load and the control issued
Order orderly carries out by different level according to intelligent electric power utilization system framework.Island intelligent power main station system summarizes each intelligent residential district energy pipe
The information on load that send in reason terminal, obtain full island it is current it is all kinds of can cutting load total amount, and sea is formed by long-term statistical analysis
The load overall characteristic on island, while the category information is transmitted to island microgrid control centre.Micro-capacitance sensor control centre is according to working as
Preload situation and part throttle characteristics make the prediction of net internal loading, and the power generation of distributed generation resource is combined to predict, provide micro-capacitance sensor
Total tune control strategy, when needing to carry out cutting load control, generation needs cutting load amount, and is handed down to system, intelligent power main website
System.
Intelligent power main station system will need cutting load amount to be sequentially allocated according to complete three type load total amount of island, if priority is higher
A certain type load cut entirely after it is still insufficient, then the choosing for continuing next group after this type load complete resection is cut,
Last type load selected according to each intelligent residential district can cutting load capacity be divided in portion, make choosing cut load accurate
The load that need to be cut with micro-grid system.
Assuming that jth type load is last type load of selection, i.e. intelligent power main station system cuts off priority in order
After the higher several type loads in front, it is remaining need to the amount of cutting to cut jth type load enough.To the jth class in each intelligent residential district
When load is allocated selection, the jth type load of intelligent residential district i need to cut capacity and can calculate as follows:
Wherein, PxqjExpression need to cut j type load total amount, PijIndicate i-th of intelligent residential district j class can cutting load total amount, n table
Show island intelligent residential district sum, dPijIndicate that i-th of intelligent residential district j class being calculated needs cutting load amount.
Intelligent power main station system be calculated each intelligent residential district it is all kinds of need cutting load capacity after, to corresponding intelligence
Cell energies management terminal sends dPijCutting load information.Wherein, if j type load needs to cut entirely, the j class of intelligent residential district i is negative
It is exactly that j type load can the amount of cutting, i.e. dP that lotus, which need to cut capacity,ij=Pij.If j type load only needs cut-out load, dPijThen press
Above-mentioned formula distribution.
Each intelligent residential district energy management terminal is communicated to upper with intelligent power main station system, calculates three type load of this cell
Total amount above gives main station system；The lower home energy administrative unit in cell is communicated, is received in home energy administrative unit
The three classes load information P ' sentkj, wherein P 'kjIndicate k-th of home energy administrative unit of this cell can cutting load amount,
And the corresponding customer charge of home energy administrative unit is arranged to j type load.In addition, intelligent residential district energy management terminal is also
Reception device failure and exception information, so that cutting load amount statistics and while sending cutting load order this abnormal device can be being rejected.
After energy management terminal in intelligent residential district receives each all kinds of information on load of home energy administrative unit, for similar negative
Respective excision priority is set dynamically in lotus again.After intelligent residential district energy management terminal receives the need amount of cutting of each type load, choosing
Each type load in cell is cut, is cut according to the sequence choosing of 1-2-3 class, similar interior then select according still further to the sequence of priority size is cut.
If cutting certain type load entirely, the order for cutting the type load entirely is sent to the home energy administrative unit of the type.If certain type load
Enough cut, then successively cut off the type load according to priority orders, until meet need to the amount of cutting until.
Island user generally compares concentration in area distribution, and number of users will not be too many, and intelligent electric power utilization system has
The large-scale application even condition of gross area covering on island, the intelligent electric power utilization system of scale application and the interaction of micro-capacitance sensor
It will be more effective.Therefore, intelligent electric power utilization system and micro-capacitance sensor technology are carried out promoting and applying as a whole on island having
