Fig. 1 is the flow chart of the energy control method of intelligent micro-grid that provides of one embodiment of the invention, and this method can be by
One energy control apparatus performs, which can be specially the setting with logic processing capability such as server
Standby, which accesses in intelligent micro-grid.As shown in Figure 1, this method comprises the following steps：
Step 101 judges whether the input energy in intelligent micro-grid is equal to output energy, if so, step 103 is performed,
If it is not, then perform step 102.
In actual scene, the input energy of intelligent micro-grid is provided by power supplys such as wind-driven generator, diesel-driven generator, photovoltaics.
Energy is exported by the load in intelligent micro-grid is mainly supplied to use, can be worked normally for load.And one in actual scene
Number of power sources and load number in a intelligent micro-grid may have multiple.Therefore, by judging in intelligent micro-grid in the present embodiment
The total of all power supplys exports the magnitude relationship between energy and all gross energies for loading needs to determine the energy in intelligent micro-grid
Whether amount is stablized.For example, when total output energy of all power supplys in intelligent micro-grid is more than the gross energy that all loads need,
Energy in intelligent micro-grid is in the state that supply exceed demand, and the mode for absorbing excess energy by energy storage device at this time can

During amount, the energy in intelligent micro-grid is in the state of supply-less-than-demand, can make in a manner that energy storage device releases energy at this time
Obtain the energy stabilization in intelligent micro-grid.
In Fig. 1, it further includes step 102, according to preset selection strategy, from multiple energy storage devices, selectes a target
Energy storage device, and charge or discharge are performed by the target energy storage device and are operated so that the energy in the intelligent micro-grid is protected
It is fixed to keep steady, wherein, the multiple energy storage device access is in the intelligent micro-grid.
In practical application, an energy storage device conduct can be determined at random from multiple energy storage devices of access intelligent micro-grid
Target device, and pass through the energy that target energy storage device absorbs superfluous energy or supplement lacks.
It is illustrated below to how to adjust energy in intelligent micro-grid by energy storage device：
By taking super capacitor as an example, Fig. 2 controls intelligent micro-grid energy for what one embodiment of the invention provided by super capacitor
Stable linear schematic diagram, the schematic diagram may be considered setting it is also assumed that being obtained by simulation means, this reality
It applies in example and is not specifically limited.In Fig. 2, horizontal axis represents the electricity percentage SoC of super capacitor, and the longitudinal axis is the maximum output of power supply
Power P n, curve a, b, c1, d1, e of horizontal axis top half represent power supply respectively：Wind-driven generator, photovoltaic, battery, power grid with
And diesel-driven generator corresponding output power, the correspondence in the electricity percentage of different super capacitors can artificially be set
It is fixed or by simulation means acquisition.C2 the and d2 curves of horizontal axis lower half portion represent different super capacitors respectively
Electricity percentage when corresponding battery and power grid output power.
Since the energy in intelligent micro-grid by super capacitor remains stable, super capacitor needs to absorb superfluous
Energy avoid the unbalance of energy in microgrid.At this moment super capacitor charges, the table of the electricity percentage of super capacitor in fig. 2
Show to be to be moved to the right direction of horizontal axis, when being moved to certain value, the output energy that can gradually have power supply is limited, and then
Energy difference between power supply and load will reduce.As super capacitor continues to charge, the electricity percentage of super capacitor is gradual
Increase, when the electricity percentage stabilization of super capacitor is when on a certain position of abscissa, the output energy of power supply is equal at this time
The energy needed is loaded, the input energy of intelligent micro-grid and output energy reach stable at this time.In addition, when plus-minus load, power supply
When output power changes, all show as the input energy of intelligent grid and export the unequal of energy, this can cause super capacitor
Electricity percentage change, and then curved line relation according to figure 1 can be again so that the energy of intelligent micro-grid reaches
Balance.
Particularly, it is contemplated that battery, super capacitor service life, can change by adjusting the charging and discharging curve of battery in Fig. 2
Become the operation interval of battery, for example discharge curve is moved to left, battery will be made only to contribute when SoC is relatively low, work as output power of power supply
When sufficient, SoC can maintain higher level, and this avoids the unnecessary losses of battery.Similar, battery charging curve is moved to right,
It charges again to battery when output power of power supply can be allowed very sufficient, this avoids the frequent chargings of battery.In addition wind is considered
There are rotary parts for the power supplys such as machine and diesel-driven generator, are not suitable for frequent start-stop, quickly adjust power, to each power supply in Fig. 2
Peak power output limits the slope for having very little, this allows each power supply slowly to adjust power, will not cause in energy shift
Impact, protects equipment.
When being assigned new demand to energy, for example electricity is utmostly surfed the Internet more than requirement, and the curve of power supply can be transferred
Point is moved to right to being close at the rightmost side (100%, Pn), and terminal is fallen in (100%, 0).In this way, when power is larger, full
Sufficient loading demand, and after battery is full of, SoC will continue to rise, that is, grid-connected power is increasing.Consider limiting case,
When power is much larger than load consuming power and energy storage absorbed power, SoC can rapid increase, until 100%, power supply is given at this time
Determine power and be restricted to 0, SoC at 100% will to stablize, i.e., grid-connected power reaches maximum value.This method can will be removed and be unloaded
Power after being consumed with energy storage is all grid-connected, realizes maximum remaining electricity online function, has preferable economy.
Optionally, it is contemplated that common energy storage device includes power grid, super capacitor and battery in practice.And it is filling among these
Influence of the discharge time to power grid service life is minimum, and secondly, and battery is by being influenced maximum for super capacitor.Optionally, originally
It, can be according to sequence of the charge and discharge number to aging effects from small to large, successively to the storage in access intelligent micro-grid in embodiment
The priority of energy equipment is configured according to sequence from high to low.For example, access intelligent micro-grid energy storage device include power grid,
The priority of power grid is then set as highest by super capacitor and battery, and super capacitor takes second place, and the priority of battery is minimum.Then,
According to the priority orders of each energy storage device, determine the energy storage device of highest priority as target energy storage device.
Optionally, Fig. 3 is the method that target energy storage device is determined according to priority orders that one embodiment of the invention provides
Flow chart, as shown in figure 3, this method comprises the following steps：
Step 201 selectes at least one energy storage device, at least one energy storage device from the multiple energy storage device
Reach the energy storage device of the first predetermined threshold value for energy.
In practical application, the first predetermined threshold value includes threshold value when corresponding input energy is more than output energy, works as storage at this time
The energy of energy equipment could perform discharge operation when being more than this threshold value, the first predetermined threshold value further includes corresponding input energy less than defeated
Go out threshold value during energy, the operation for absorbing energy could be performed when the energy of energy storage device is less than this threshold value at this time.Therefore, when
The input energy of intelligent micro-grid be more than output energy when, the present embodiment from access intelligent micro-grid multiple energy storage devices in select to
A few energy is more than the energy storage device of respective threshold, and when the input energy of intelligent micro-grid is less than output energy, then from connecing
Enter and the energy storage device that at least one energy is less than respective threshold is selected in multiple energy storage devices of intelligent micro-grid.
In figure 3, step 202, the energy storage for selecting highest priority at least one energy storage device can also be included
Equipment is as target energy storage device.
As an example it is assumed that in the energy storage device of access intelligent micro-grid, power grid, super capacitor and battery have reached preset
First predetermined threshold value, then using the power grid of highest priority as target energy storage device.
At least one energy is chosen from multiple energy storage devices to meet the energy storage device of predetermined threshold value requirement by elder generation, then from
Selected at least one energy storage device highest priority as target energy storage device, being not only able to, which reduces single energy storage, sets
Standby charge and discharge number improves the service life of energy storage device, additionally it is possible to, it is ensured that selected target energy storage device is in available
Energy state, improve the reliability of energy hole.
In Fig. 1, step 103 is further included, the input/output state for keeping intelligent micro-grid current is constant.
Particularly, it in order to which the input energy of intelligent micro-grid and output energy is made to reach balance as early as possible, is being held in practical application
It, can also be by adjusting the energy input or load number in intelligent micro-grid so that described while the row above method or later
The input energy of intelligent micro-grid is equal to output energy.
Specifically, when the input energy in intelligent micro-grid is more than output energy, generated electricity by reducing non-renewable energy resources
The energy output of equipment (such as coal generating equipment, diesel-driven generator etc.) increases the mode of load number to make intelligent micro-grid
In energy reach balance.It, can be by improving regenerative resource when the input energy in intelligent micro-grid is less than output energy
The energy output of generating equipment (such as wind-driven generator, photovoltaic etc.) reduces the mode of load number to make in intelligent micro-grid
Energy reaches balance.
Wherein, in the method by adjusting load number, in order to ensure that important load is finally cut out, in reality
In, load can be classified according to the significance level of load, when the energy to intelligent micro-grid is adjusted, can will born
Carry according to important level sequence from low to high cut out or by load according to important level sequence from high to low access, with
Achieve the purpose that energy in stable intelligent micro-grid.Specifically, as shown in figure 4, significance level from high to low suitable according to load
Load can be divided into Level1, Level2, Level3 ..., wherein Level1 grades highest, put into, finally cut out at first by sequence.
When electricity percentage SoC reaches certain value, it is meant that have certain energy reserve in intelligent micro-grid, at this time by Level1 grades
Load input intelligent micro-grid.And will be so that load is cut out when the input energy deficiency of intelligent micro-grid, load is cut out and meeting
Cause energy surplus, the electricity percentage SoC in intelligent micro-grid rises, and load can be made to be put into again.In order to avoid load
By frequent switching, it can be delayed certain time after load is cut out, could be put into again after the completion of delay.If intelligent micro-grid
In energy it is sufficient, the electricity percentage SoC in intelligent micro-grid will continue to rise, and the load of input can be more and more, Deng Daoneng
During amount balance, SoC will stabilise at certain point.If when the input energy in intelligent micro-grid reduces, the SoC in intelligent micro-grid can drop
It is low, load can step by step be cut out from low to high by significance level.
The present embodiment, by judging, and work as intelligent micro-grid the input energy in intelligent micro-grid and output energy
In input energy not equal to output energy when, according to preset selection strategy, from multiple energy storage devices of access intelligent micro-grid
In, it selectes an energy storage device and the energy in intelligent micro-grid is absorbed or supplemented, energy in intelligent micro-grid is kept so as to reach
Stable purpose is measured, by this present embodiment one can be selected as suction from multiple energy storage devices in access intelligent micro-grid
The equipment received or released energy, therefore, it is possible to reduce the number of single energy storage device charge and discharge, that improves energy storage device uses the longevity
Life.In addition, can also the smaller storage to aging effects of charge and discharge number be increased by the setting to selection strategy in the present embodiment
