It calculates rule and calculates the electric power networks voltage load that crosses the border or occur occurs and cross the border.In other words, according to the power supply volume of object space
Load judgement with object space includes the situation of crossing the border of the electric power networks of the virtual energy storage system, and then according to actual
Situation of crossing the border is adjusted correspondingly electric system.Specifically, situation of crossing the border includes that electric power networks generation voltage crosses the border/occurs
Load crosses the border and the simultaneous situation of both the voltage of electric power networks and load.
It is understood that when there is no cross the border situation namely electric power networks for the corresponding electric power networks of object space
Voltage and load there is no crossing the border when, then it represents that current power supply volume and load is in equilibrium state, therefore does not need
It adjusts；When voltage, which occurs, for the corresponding electric power networks of object space crosses the border, indicate excessive to the power supply volume of object space, therefore
It needs to increase load, opens the air-conditioning of object space, virtual energy storage system is made to be in charged state；When load occurs for object space
When crossing the border, indicate that the load of object space is excessive, it is therefore desirable to reduce load, that is, close the air-conditioning of object space, make virtual
Energy-storage system is in discharge condition.
More specifically, in the present embodiment, be judged by way of Load flow calculation electric power networks occur voltage cross the border or
Load crosses the border, and in other examples, can use other algorithms and is judged that the present embodiment does not limit this.

Air-conditioning in object space processed opens or closes.
The characteristic of the thermal inertia in cold air and object space stored in object space according to air-conditioning, by target empty
Between be equivalent to virtual energy storage system, and participate in using virtual energy storage system the regulation of the voltage and load in electric power networks, thus
The opposite tide of electric system effectively is avoided, to improve the power quality in electric system；In addition, this method can be according to electric power
The development of system adjusts virtual energy storage system model, to neatly control electric system；And compared to existing
Have in technology by way of upgrading active distribution network network or setting energy storage device, this method can be according to original power network
Network is managed control, haves no need to change the hardware configuration of electric power networks, to economize on resources, reduces economic input cost.
Fig. 2 is the process of another control method of electric power system based on active distribution network provided in an embodiment of the present invention

Control force is weaker, therefore in the present embodiment, sets multiple for the quantity of object space.The particular number of object space according to
Practical application request setting, can be hundreds and thousands of, this example does not limit this.
Specifically, due to the quantity of object space be it is multiple, the temperature profile parameter of each object space may be each not phase
With, therefore virtual energy storage system model corresponding with each object space is established according to the temperature profile parameter of each object space,
Each virtual energy storage system model characterizes the indoor temperature change generated in case rate of each corresponding object space.In the space according to object space
After characteristic parameter and virtual energy storage system model obtain virtual energy storage system corresponding with object space, advised according to preset polymerization
It is then virtual energy storage systematic polymerization body by multiple virtual energy storage system combinations.That is, by the corresponding void of multiple object spaces
Quasi- energy-storage system is polymerize, and virtual energy storage systematic polymerization body is obtained, to participate in electric power using virtual energy storage systematic polymerization body
The control of system.In specific implementation, the quantity of the virtual energy storage system in each virtual energy storage systematic polymerization body can be not
With, and can be and the negative of virtual energy storage systematic polymerization body is calculated by aggregate response (aggregated response)
Lotus amount.In specific implementation, usually by multiple virtual energy storage system combinations be virtual energy storage systematic polymerization body, and by pair
Different multiple virtual energy storage systems are integrated respectively, obtain multiple virtual energy storage systematic polymerization bodies.For example, being 1 by number
Virtual energy storage system combination to 10 is the first virtual energy storage systematic polymerization body, and the virtual energy storage system for being 11 to 30 by number is whole
It is combined into second virtual energy storage systematic polymerization body etc..
It is corresponding, S30: renewable energy system is input to the power supply volume of object space and the load of object space
It include to determine that electric power networks occur the voltage load that crosses the border or occur and cross the border in the electric power networks of virtual energy storage system specifically:

Specifically, participating in the control method of electric system using virtual energy storage systematic polymerization body specifically: by renewable energy
It includes that virtual energy storage system is poly- that source system, which is input to the power supply volume of multiple object spaces and the load of multiple object spaces,
In fit electric power networks, judge that electric power networks generation voltage crosses the border or load crosses the border using tidal current computing method.Obtaining electricity
After the situation of crossing the border that pressure is crossed the border or load crosses the border, then need to be adjusted virtual energy storage systematic polymerization body, due to virtual energy storage
Corresponding systematic polymerization body is multiple virtual energy storage systems, and each virtual energy storage system is corresponding with object space respectively, therefore
Exactly turning on or off according to the air-conditioning in the situation control object space that crosses the border.
As it can be seen that a kind of control method of electric power system based on active distribution network provided in this embodiment, by by multiple mesh
Marking the corresponding virtual energy storage systematic polymerization in space is virtual energy storage systematic polymerization body, participates in electricity using virtual energy storage systematic polymerization body
The control of Force system can further increase the efficiency of the electric power system control based on active distribution network.
On the basis of the above embodiments, the present embodiment has made further instruction and optimization to technical solution, specifically,
S40: it is opened or closed according to the air-conditioning in the situation control object space that crosses the border specifically:
S41: the target control amount of electric power networks is calculated according to situation of crossing the border；
S42: the target control component of each virtual energy storage systematic polymerization body is calculated according to default computation rule；
S43: it is controlled in each object space corresponding with each virtual energy storage systematic polymerization body according to each target control component
Air-conditioning opens or closes.
Specifically, calculating the target of electric power networks according to situation of crossing the border after obtaining the situation of crossing the border of electric power networks
