It is fixed.It is electrical power of i-th of distributed busbar protection in t moment,It is hot merit of i-th of distributed busbar protection in t moment
Rate.Need to illustrate: the form of the cost of distributed busbar protection not necessarily formula (2), the form be distributed busbar protection at
This common description method.
S112: the electric power system model of cogeneration integrated energy system is established；
Electric system needs to guarantee the equilibrium of supply and demand of electric energy, i.e., the sum of distributed energy electrical power and load in electric system
The difference of the sum of the electrical power of consumption should be 0, and corresponding formula is as follows:
Wherein,It is the electrical power that i-th of load is consumed in t moment.

NhIndicate the set of all heating system nodes.
The heat supply network of heating system is made of pipeline interconnected, and since heating system uses dynamic model, there are the times
Delay and temperature dynamic process, therefore closed using the temperature that the pipeline equation of heat conduction of differencing defines a root canal road first and last section
System, corresponding formula are as follows:
Wherein, P is the set of all heat-net-pipelines,It is i-th of water supply line in t moment to pipeline first section x distance
The temperature at place,It is flow of i-th of water supply line in t moment, Δ t is given time interval, and Δ x is between given distance
Every ρ is the density of heat transfer medium (usually water), CpIt is heat transfer medium specific heat capacity,It is water supply line cross-sectional area,It is ring
Border temperature.The physical schematic of the equation is as shown in Figure 3.
Further, in heat supply network, there are following relationships for pipe temperature and node temperature:
Pipeline head end temperature is equal to the node temperature that pipeline head end is connected, and corresponding formula is as follows:
Temperature after pipe end temperature mixing is equal to the temperature of pipe end connected node, the corresponding following institute of formula
Show:
Wherein,It is i-th of node temperature,It is the collection for all node is being connected with pipeline j head end, end
It closes.
To guarantee that node energizes quality, node temperature cannot be below limit value, while to ensure safety and stability, node temperature
Cannot be excessively high, therefore node temperature needs to meet following constraint:
Wherein,It is maximum value, the minimum value of node heat supply temperature respectively.

The situation of satisfaction；WithIt is fixed step size, NT, failIt is all pipeline/node device set for being unsatisfactory for constraint, KjIt is
It is unsatisfactory for the correction factor of restraint device for i-th, different value is taken according to pipeline/node type difference.
S460: judge whether the feasible zone cut value is preset threshold；
S470: if preset threshold, then solving result is exported；
S420: if not preset threshold, then returning and execute the solution convex Optimized model, comprehensive to obtain cogeneration
The step of closing the electric thermal power output valve of distributed busbar protection in energy resource system, wherein using the feasible zone cut value as institute
State the input of convex Optimized model.
In the present embodiment, preset threshold 0 illustrates that integrated energy system reaches if obtained feasible zone cut value is 0
Optimal and meet institute's Prescribed Properties, iteration terminates at this time, exports solving result.If obtained feasible zone cut value is not 0,
The feasible zone cut value is back to convex Optimized model, as the input of convex Optimized model, to continue to iteratively solve, until feasible
Domain cut value is 0.
Technical solution disclosed in the present embodiment, teach using Decomposition iteration method solving optimization scheduling model principle and
Process, this method consider the network constraint of power grid, heat supply network, it is contemplated that the dynamic process of heating system, it is contemplated that heat supply network exists
Labyrinth and changeable flow adjustment mode, to improve economic benefit and society of the distributed energy in integrated energy system
Benefit.
Referring to Fig. 6, third embodiment of the invention also provides a kind of Optimization Scheduling of energy resource system, the present embodiment
