Etc. module (not shown).
Specifically, the microgrid energy management system 70 of the present invention can realize active power and Reactive Power Control merit
Energy.As shown in Figure 4, it is shown that showing of a kind of structure that the microgrid energy management system 70 of the present invention controls for realizing power
It is intended to.
Wherein, this microgrid energy management system 70 includes:
Electric quantity acquisition module 700, for online acquisition micro-capacitance sensor parameter and Large Copacity energy-storage system parameter information, described
Micro-capacitance sensor parameter includes that voltage, electric current, meritorious, idle, frequency information, described Large Copacity energy-storage system parameter include voltage, electricity
Stream, discharge and recharge information；
Message processing module 701, for receiving the micro-capacitance sensor parameter from electric quantity acquisition module and Large Copacity energy storage system
System parameter, by the information received being integrated, processing and computational analysis, it may be judged whether need to carry out power adjustments, and
Formulate power adjustments strategy when determining and needing to carry out power adjustments, and generate control signal；
Power control module 702, for receiving the control signal from described message processing module, controls letter according to described
Number perform corresponding active power regulation or reactive power regulation.
Specifically, when message processing module 701 determines voltage appearance fluctuation beyond predetermined threshold, it is determined that need to open
Dynamic micro-capacitance sensor active power regulation；When message processing module 701 determines frequency appearance fluctuation beyond predetermined threshold, it is determined that
Need to start the regulation of micro-capacitance sensor reactive power；
Wherein, described power control module 702 farther includes active power regulation module 703 and reactive power regulation mould
Block 704；
Described active power regulation module 703, for when electricity surplus, controls Large Copacity energy-storage system and super electricity
Appearance group is charged, and for when electricity deficiency, controls to discharge, Large Copacity energy-storage system and super capacitor group with reality
The dynamic equilibrium of existing active power；
Described reactive power adjustment module 704 is for idle to realize by reactive power compensator is thrown, cut operation
The dynamic equilibrium of power.
It is understood that described reactive power compensator can be independent device herein, it can include reactive-load compensation
Equipment (including Capacitor banks, Reactor banks), switchgear and control accordingly, protect, measure, communication apparatus.
Combine Fig. 5 in the lump, it illustrates the operation principle schematic diagram of Fig. 4 microgrid energy management system 70.
It can be seen that electric quantity acquisition module 700 gathers the information such as micro-capacitance sensor voltage, electric current, meritorious, idle, frequency,
And the information such as the voltage of Large Copacity energy-storage system, electric current, discharge and recharge, and send message processing module 701 to.Information processing mould
Block 701 receives the information such as the micro-capacitance sensor voltage from electric quantity acquisition module 700, electric current, meritorious, idle, frequency, and Large Copacity
The information such as energy-storage system voltage, electric current, discharge and recharge, by integrating the information received, processing and computational analysis, it is judged that
The need of carrying out power adjustments.In one example, this decision logic can be such that
When voltage fluctuation occurs compared with big (the 7% of the absolute value sum overrate of the positive and negative deviation of line voltage), really
Surely power adjustments need to be carried out；
When fluctuation relatively big (e.g., frequency departure exceedes ± 0.5 hertz) occurs in frequency, determine and need to carry out power adjustments.
If it is determined that determine and need to carry out power adjustments, then formulation power adjustments strategy:
Specifically, when voltage, relatively big (e.g., the absolute value sum overrate of the positive and negative deviation of line voltage of fluctuation occurs
7%) time, start micro-capacitance sensor reactive power regulation；
When fluctuation relatively big (e.g., frequency departure exceedes ± 0.5 hertz) occurs in frequency, start micro-capacitance sensor active power and adjust
Joint.
Power adjustment information is changed into control signal by message processing module 701, exports control signal to Electric control
Module 702.Power control module 702 goes to perform meritorious, reactive power regulation by receiving control signal.Specifically, if electricity
Surplus, active power regulation module 703 then outputs signal to battery management system, to large-capacity battery group and super capacitor group
It is charged；If electricity is not enough, active power regulation module then outputs signal to battery management system, to large-capacity battery group
Discharge with super capacitor group, thus realize the dynamic equilibrium of active power.Reactive power adjustment module 704 is then by nothing
Reactive power compensation installations (including Capacitor banks and Reactor banks) carries out throwing, cut operation realizes the dynamic equilibrium of reactive power.If system
Judging to be made without power adjustments, system then proceeds online information about power collection, until needing to carry out power adjustments to be
Only.
As shown in Figure 6, it is shown that the structural representation of micro-capacitance sensor management system 71 in Fig. 3 of the present invention.Wherein, this micro-capacitance sensor

Wherein, this micro-capacitance sensor Centralized Controller 714 is for detection micro-capacitance sensor frequency in real time, if be detected that underfrequency,
Then according to the priority cut-out the most successively load of load, or adjust distributed power source output, so that micro-capacitance sensor frequency
Rate is in normal range；
If be detected that frequency is too high, then recover the most successively according to the priority of the load excised, or
Adjustment distributed power source exports, so that micro-capacitance sensor frequency is in normal range.
Specifically, micro-capacitance sensor Centralized Controller 714 can be that a embedded micro-capacitance sensor main frame is held concurrently operator station, and it can be complete
Face monitors the ruuning situation of whole micro-capacitance sensor primary equipment, analyzes in real time the ruuning situation of micro-capacitance sensor and to obtain whole micro-capacitance sensor excellent
Changing and adjustable strategies fast automatic execution, at the same time as database server, it is the core of microgrid energy management system
Heart parts.
During islet operation, micro-capacitance sensor Centralized Controller 714 checks micro-capacitance sensor frequency at any time, if frequency rises, then
The load that recovered part has been excised, all puts into frequency the most too high, then uses excision distributed power source if all of load
Measure or adjustment distributed power source are exerted oneself, if frequency drops to the minimum limit value (frequency departure-0.5 hertz) of permission, then continue
Continuous excision remainder load, it is ensured that the reliability of most important load supplying and power supply quality during off-network.
Island load is according to load important degree and user's request definition multilevel precedence, the most in one example, and can
To define level Four priority, sort as follows:
First priority: isolated island military affairs I level loads；
Second priority: the load of isolated island military affairs II level, industry I level load, the load of life I level；
Third priority: isolated island military affairs normal load, industry II level load, the load of life II level；
4th priority: isolated island industry normal load, isolated island life normal load.
When excision load by load important degree, according to load priority, first excision load priority is low insignificant
The important load that load priority is high is cut in load again, and the adjustment exerting oneself distributed power source, principle is preferentially to ensure renewable energy
The EIAJ generating in source, even finally can reach by the way of energy storage device is changed into charging by electric discharge and absorbs unnecessary electricity
Equilibrium of supply and demand target after micro-capacitance sensor off-network.
