The SOC value for measuring the energy-storage battery of router carries out second layer coordinated control to micro-capacitance sensor by energy router, specifically:
Preset value in the step 1022 is 410V；
When the SOC value that DC bus-bar voltage is in island state and energy-storage battery in 390V or less, energy router is small
When being equal to 10%, energy-storage battery is controlled by energy router and is stopped working；

Low-voltage direct is loaded and is accessed by load port, is accessed AC load by AC load port, is passed through High-voltage AC Network end
Mouth accesses High-voltage AC Network, as shown in Figure 2.
For example, remaining capacity of the High-voltage AC Network port for the absorption energy router in grid-connect mode, when
It is replenished in time when energy router energy deficiency and supports busbar voltage, energy is between High-voltage AC Network and energy router
It is two-way flow；The common three-phase alternating current load energy supply that it is 380V that the AC load port, which is for line voltage, energy list
Mutually flow；The DC low-voltage load port is that the DC load of low-voltage energizes, and reduces intermediate conversion links and improves energy benefit
With rate；The DC bus, which loads, can be divided into distribution type renewable energy system, energy-storage battery and other 3 classes of load, and described point
Cloth renewable energy system includes wind-power electricity generation and PV (photovoltaic power generation), and the energy-storage battery is primarily to maintain direct current female
The stabilization of line voltage, plays peak load shifting.
In order to work normally energy router, normal load power need to be less than energy-storage battery output power, energy-storage battery
Power is less than the power of energy router:
Pload< Pbattery< Prouter
Wherein, PloadIndicate load rating power；PbatteryIndicate energy-storage battery rated power；ProuterIndicate energy routing
Device power.
Realize that the specific control strategy of this programme is as follows:
Energy router carries out coordinated control according to DC bus-bar voltage:
When DC bus-bar voltage maintains within the scope of 390~410V, energy router is in grid connection state or island state,
When the power of renewable energy system and the equal power of load consumption, the energy routing when energy router is in grid connection state
Device is in sagging control.Energy-storage battery is continued working in charge and discharge mode in order to prevent, and energy-storage battery is in halted state at this time.
, can be when raw energy resource system power be less than bearing power when energy router is in isolated island, power on DC bus
Imbalance cause DC bus-bar voltage to decline.When DC bus-bar voltage is lower than 390V, at this time in order to maintain power-balance to store up
Energy battery discharges, and works in hang, maintains busbar voltage near 390V.
When energy router works in island mode and when overload situations occurs in load, DC bus-bar voltage be will continue to down
Drop, when DC bus-bar voltage is lower than 380V, energy-storage battery work at this time is in constant-current discharge state, to maintain DC bus-bar voltage
In 380V or more, energy router carries out cutting loaded work piece.
When the power of renewable energy system is larger, DC bus-bar voltage rises, when more than 410V, energy-storage battery at this time
It into charge mode, charges by sagging control, stablizes DC bus-bar voltage in 410V.Energy router is likely to be at this time
Grid connection state or island state, when energy router work is in grid-connect mode, energy router works in constant current state.
When DC bus-bar voltage continues to be increased beyond 420V, energy-storage battery work at this time is in constant current charging mode.In order to
Maintain DC bus-bar voltage in a certain range, renewable energy system, which need to be abandoned, to be run, i.e. PV and wind-power electricity generation all work
Constant voltage mode.
Isolated island control:, at this time can be when energy router is in island mode and busbar voltage is in 390V or less
Raw energy resource system power is less than bearing power and sacrifices the work of secondary load to guarantee the working time of important load as far as possible
Time, energy router can carry out different cutting loaded work piece according to the SOC value of the energy-storage battery of energy compatibility controller monitoring.
Load is divided into A class, B class, C class totally 3 class by the significance level according to load, wherein A class is cannot have a power failure load, B class and C class
The load that can have a power failure can be divided into.Cut that load table is as shown in table 1, when the SOC value of energy-storage battery is lower than 10%, energy-storage battery
Into halted state.
The load excision situation table of table 1
| SOC value | ≤ 10% | 10%~20% | 20%~30% | >=30% |
| Excision load | Stop | BC | C | Nothing |
Energy-storage battery power control: energy-storage battery power control improves energy mainly for the energy storage capacity of optimization energy-storage battery
Amount router copes with the ability of some catastrophic failures in island state, so that energy router is received upper layer allotment and realizes
Energy internet.When DC bus-bar voltage is within the scope of 390~410V, energy-storage battery is in halted state, although can have
The service life of the extension energy-storage battery of effect but the ability for reducing energy router reply catastrophic failure.For example, working as direct current
When busbar voltage is within the scope of 390~410V and when energy router enters grid connection state by island state, energy-storage battery
The energy of energy-storage battery cannot be replenished in time because not working, when island state occurs again, energy-storage battery cannot be for a long time
Load energy supply.When the energy storage capacity of energy-storage battery is relatively high, energy-storage battery cannot timely be seen energy off.Therefore, this hair
The bright method using energy-storage battery power control improves the ability that energy router copes with some catastrophic failures.When energy compatibility control
The SOC value of the energy-storage battery of device processed monitoring is lower than 40% or when being higher than 70%, and energy router detects whether grid-connected automatically, works as inspection
Measure grid connection state and when DC bus-bar voltage is within the scope of 390~410V, energy-storage battery work is switched by still-mode
To constant current charge-discharge mode, the autonomous charge and discharge of energy-storage battery are realized.
