Embodiment 2
The present embodiment utilizes method of the invention, is carried out with the example of integrated energy system actual scene as shown in Figure 5
Actual test；
Specifically, being mainly made of following 3 part in the integrated energy system: the IEEE14 node power distribution net system of modification
System, 11 node natural gas distribution systems, 11 node heat distribution pipe network systems；Energy stream carries out coupling by energy source station and hands over energy
Mutually, the alternate node of energy source station access are as follows: 4,9,11 nodes of distribution network system, 1,7 nodes of natural gas distribution system, heating power
8,11 nodes of pipe network system, device parameter to be selected is as shown in table 1 in energy source station.
1 EH of table device parameter list to be selected
Finally obtain configuration result of the present invention in integrated energy system test example, the energy under gained different scenes
Type selecting of standing addressing result.
It according to table 2 as it can be seen that since electric load fluctuation is larger, needs to balance in time, adds trend constraint, distribution network
There is still a need for other equipment to supply in time for the upper node load far from fired power generating unit, since renewable energy power output is uncertain, no
Workload demand can be met in time, therefore accessed energy source station in the node of distribution network 4.
Configuration result of 2 present invention of table in test example
4 nodes are connected to a Wind turbines, when renewable energy power output is greater than workload demand, using coupling in energy source station
Equipment dissolves electric power more than needed；When renewable energy power output is unable to satisfy workload demand, obtained by energy source station by other energy
The electric energy of network supply；Since electricity-cold Coupling device, electric-thermal Coupling device have, energy conversion efficiency is high, equipment construction cost
Relatively low characteristic, can be more likely in the case where meeting system load demand selection using electric energy carry out energy conversion with
The Coupling device of supply；Due in energy source station it is to be selected be energy conversion and supply are carried out using natural gas Coupling device based on,
Therefore energy source station has been accessed in 1 node of natural gas network；In addition to the influence of seasonal factor, thermal load demands are relatively stable, together
When, since heat distribution pipe network system itself has certain energy storage capability, it can make full use of pipe and deposit, it is heat that energy source station, which is added,
Solenoid net increases energy conversion ability, therefore pays the utmost attention to carry out energy using thermal energy of having more than needed in natural gas network and heat distribution pipe network
Amount supply selects the AC and GB of large capacity to access in 8 nodes of natural gas network.
Equally in integrated energy system as shown in Figure 2, with the minimum upper layer target of Life cycle cost, with energy base
It is up to the addressing type selecting that energy source station is carried out under the target pattern S2 of lower layer's target in the system energy transfer efficiency of energy quality character
Configuration, configuration result are as shown in table 3.
Configuration result of the 3 target pattern S2 of table in test example
Due to not considering that the economic factor of system influences in the energy conversion efficiency based on energy quality character, system is being run
When do not consider economic benefit, cause operating cost to increase；However, energy resource base is to consider economic input and human resources in S1
The system energy transfer efficiency of input, can plan as a whole energy conversion efficiency and economic benefit.Since upper 4 node of EPS accesses wind-powered electricity generation
Unit capacity is larger, but load is smaller, and the EH of S2 is still accessed in 4 nodes of EPS；8 nodes of DHS are important cold heat load points,
To guarantee energy conversion efficiency and workload demand, therefore still accessed in 8 nodes of DHS；Therefore, in table 3, the EH of S2 plans knot
For fruit compared with the result of S1, on-position is identical as the result of S1, and equipment component selects the larger model of energy conversion efficiency, but raw
Life cycle costing is ordered to increase.
Equally in integrated energy system as shown in Figure 2, the minimum upper layer target of construction cost is run every year with system,
It is up to the addressing type selection that energy source station is carried out under the target pattern S3 of lower layer's target, configuration result such as table with energy resource base
Shown in 4.
Configuration result of the 4 target pattern S3 of table in test example
S3 lower layer target is still system energy resource base, has contemplated that part economic factor, leads to on-position and the S1 of EH
Unanimously；Under the premise of meeting workload demand, to pursue lower Construction and operation cost, turn due to carrying out the energy using electric energy
The Coupling device construction cost change, supplied is higher, selects the lower equipment of the relatively small price of capacity；Due in upper layer model
In do not consider system in construction, the cost of disenabling stage, but by the way that utilization rate can be worth to portion big in system in underlying model
Divide economic behaviour to propose certain requirement, ensure that the economic benefit of system operation；Therefore, in table 4, the rule in target pattern 3
For check off fruit compared with the result of S1, on-position is identical as target S1, but due to the economic behaviour of Consideration in the target of upper layer
Less than underlying model, while leading to portion's economic benefit better than S1, energy resource base is lower than S1.
Equally in integrated energy system as shown in Figure 2, the minimum upper layer target of construction cost is run every year with system
Target pattern S4 under carry out the addressing type selection of energy source station, configuration result is as shown in table 5.
Configuration result of the 5 target pattern S4 of table in test example
Electric energy energy grad highest, thus it is higher using the Coupling device transfer efficiency that electric energy is coupled, since S4 is
Only consider that system energy transfer efficiency, systems organization operating cost are selected under the premise of guaranteeing that system operation cost is alap
The bigger electrical coupling device of capacity is selected, EH selection is connected to the 6 nodes access of fired power generating unit on EPS；11 nodes are more water supplying pipes
The connection hinge in road, and pipe diameter is big, transmission speed is fast, can effectively improve heating efficiency, therefore select 11 nodes in NGS
Access EH；The mode is most traditional plan model, and the rule to system Life cycle energy economic behaviour are lacked in objective function
It draws, causes to have ignored departmental cost in the planning process of EH；Therefore, in table 5, the program results of S4 are compared with S3, Quan Sheng
Life life cycle costing is higher than S3 and shows the economic benefit of the program results of S4 simultaneously as the economic benefit of S3 is poor compared with S1
It is poor compared to S1.
Fig. 6 is illustrated under different scenes, the wind electricity digestion capability rate and Life cycle of integrated energy system programme
The comparative situation of cost.As shown, the wind electricity digestion rate of S1 is higher than remaining all scene, Life cycle cost is lower than remaining
All scenes.It can be seen that it is proposed by the present invention based on life cycle with can be worth theory integrated energy system planing method, Ke Yiyou
