In step s 701, the first distributed energy resource system is if it is determined that its own needs to carry out energy scheduling, then to distribution Other distributed energy resource systems in formula energy network system send information on bidding；Wherein, first distributed energy resource system can For any distributed energy resource system in distributed energy network system, the information on bidding transmitted by it includes required scheduling Energy source type.

In the embodiment of the present invention, the first distributed energy resource system can determine to need energy scheduling in several ways, citing For, the load of certain energy source type is higher, and the supply of its own is not if it is determined that it is present for the first distributed energy resource system Can meet the needs of load, then can determine that its own needs to carry out energy scheduling.Or if the first distributed energy resource system is true Although the balance of supply and demand can be reached by determining its own, its unit energy cost will than the minimum unit energy cost of its own Height, select from other distributed energy resource systems dispatch the energy on the contrary than itself production the energy it is more cost-effective, then may be used Determine that its own needs to carry out energy scheduling.

In step S702, other distributed energy resource systems in distributed energy network system can receive first point The information on bidding that cloth energy resource system is sent, introduces specific scheduling flow by taking the second distributed energy resource system as an example below, Wherein second distributed energy resource system refers to appointing in addition to the first distributed energy resource system in distributed energy network system One distributed energy resource system.

Second distributed energy resource system receives the information on bidding that the first distributed energy resource system is sent, and is believed according to the bid The energy source type of scheduling needed for the first distributed energy resource system that breath includes, however, it is determined that participate in submitting a tender, then it is distributed to first Energy resource system sends bid information.Wherein, the bid information includes the Demand Side Response of second distributed energy resource system, pin The scheduling interval that can be provided to energy source type second distributed energy resource system dispatched needed for the first distributed energy resource system, And unit energy cost corresponding to each scheduling quantum in scheduling interval.

Wherein, it is transferable to refer to that the second distributed energy resource system includes for the Demand Side Response of the second distributed energy resource system Load, load that can be including reduction plans, interruptible load.For the energy class dispatched needed for the first distributed energy resource system The scheduling interval that type second distributed energy resource system can be provided refer to [0, maximum energy supply amount-current energy supply Amount], i.e., what the maximum energy supply amount of distributed energy resource system and the difference of current energy supply amount were formed from 0 to the second closes Section, any value in the section are the scheduling quantum that the second distributed energy can provide.Each tune in scheduling interval Measurement corresponds to a unit energy cost, and the unit energy cost refers to energy supply amount of the second distributed energy resource system etc. When current energy scheduling amount adds any scheduling quantum, the cost of cost, its unit can be needed for the production of unit source Member/joule.

In the embodiment of the present invention, the second distributed energy resource system can calculate its own pin before bid information is sent To maximum energy supply amount corresponding to each energy source type, can into distributed energy network system other distributed energy systems Unit energy cost corresponding to the scheduling interval that system provides and each scheduling quantum in scheduling interval.Fig. 8 is real for the present invention Apply the distributed energy resource system of one kind second provided in example calculate maximum energy supply amount corresponding to its each energy source type, can The scheduling interval and each in scheduling interval that other distributed energy resource systems provide into distributed energy network system Schematic flow sheet corresponding to scheduling quantum corresponding to the method for unit energy cost, as shown in figure 8, comprising the following steps S801 extremely Step S803：

Step S801：Second distributed energy resource system determines institute according to preset data, default energy processing plan State the maximum energy supply amount of the second distributed system；

Step S802：Maximum energy supply amount and second distributed energy according to corresponding to each energy source type The current energy supply amount of each energy source type of system, determine the scheduling interval that can be provided for each energy source type；Its In, the scheduling interval is [0, maximum energy supply amount-current energy supply amount]；

Step S802：For any scheduling quantum in the scheduling interval, according to any scheduling quantum and use Energy supply amount corresponding to each energy source type of second distributed energy resource system after any scheduling quantum, by solving target letter Number and the 3rd constraints, unit energy cost corresponding to any scheduling quantum is calculated, and use any scheduling The energy output quantity of each unit in second distributed energy resource system described in during amount.

If regarding the energy scheduling method in the embodiment of the present invention as a problem solving process, will can entirely divide Solution procedure (i.e. step S701 to the energy scheduling described in step S706 bulk flow in cloth energy network system scope Journey) regard the solution of upper layer issue as, then in the case where the solution procedure in the range of some distributed energy resource system can be regarded as The solution of layer problem.The essence of lower layer problem is set optimization problem, and main purpose is to reach the energy supply of upper strata scheduling On the premise of amount, the unit output of all kinds of energy devices in Optimum distribution formula energy resource system, so as to reduce whole distributed energy The operating cost of source network system.Therefore, lower layer problem should be entered first during the energy scheduling of the embodiment of the present invention Row solves, then after drawing the optimal solution space (referring to the unit commitment in distributed energy resource system) of lower layer problem, then will It substitutes into the solved function on upper strata as parameter, carries out the solution of macroscopic aspect.

Fig. 9 is the schematic flow sheet that lower layer problem solves in the embodiment of the present invention, with reference to Fig. 8 and Fig. 9 to the present invention Lower layer problem solution procedure in embodiment describes in detail：

In step S801, the second distributed energy resource system first according to preset data, default energy processing plan, it is determined that Go out the maximum energy supply amount of each energy source type of second distributed system.

Wherein, preset data mainly includes data unit operation, Unit Economic parameter, weather prognosis data, load prediction Several classes such as data, specific data unit operation refer to the running status of each unit in second distributed energy resource system, For example current energy supply amount accounts for the ratio of unit Maximum Supply Quantity in normal operation, or in maintenance down state； Unit Economic parameter refers to specifications parameter of the unit in economic aspect, such as the cost of the cost of unit starting once, unit Generate a kilowatt cost of consuming etc.；Meteorological preset data is primarily referred to as to the renewable money in second distributed energy resource system The ambient parameter that source generator unit has a great influence, such as environment temperature, wind speed, intensity of illumination；Default load data refers to this The load of all kinds of energy source types in second distributed system, including electric load, thermic load, refrigeration duty etc., if electric load compared with Height, then mean to the supply of increase agency.

Default energy processing plan includes the conventional power unit start and stop of second distributed energy resource system, processing plan, foundation The intermittent renewable energy that ambient parameter obtains, which is contributed, to be predicted, and accumulating plan, demand response plan etc..

Then, in step S802, the second distributed energy resource system can be according to each energy obtained in step S801 Maximum energy supply amount corresponding to type, and the current energy supply amount of its own each energy source type under current state, Determine to be directed to scheduling interval corresponding to each energy source type, the scheduling interval is [0, maximum energy supply amount-current energy supplies It should measure].

In step S803, for any in the scheduling interval corresponding to any energy source type in each energy source type Scheduling quantum, the second distributed energy resource system is according to any scheduling quantum and using the second distributed energy system after any scheduling quantum Unite energy supply amount corresponding to each energy source type, pass through the following object function of particle swarm optimization algorithm and the 3rd constraint article Part, unit energy cost corresponding to any scheduling quantum is calculated, and using the second distributed energy during any scheduling quantum The energy output quantity of each unit in system：

Object function：

3rd constraints：

Specifically, the 3rd above-mentioned constraints refers to after any of the above-described scheduling quantum is considered, the second distributed energy system The output of unit combines in system, for including K platform units in even the second distributed energy resource system, then the energy output of K platforms unit Measure sum and be equal to the energy supply amount considered after any scheduling quantum in the second distributed energy resource system.Due to meeting K platform machines The energy supply amount sum of group is equal to the bar for considering the energy supply amount after any scheduling quantum in the second distributed energy resource system Under part, there is a variety of Unit Combinations, and therefore, for any Unit Combination, the second distributed energy resource system will use above-mentioned Object function, to calculate unit energy cost corresponding to each Unit Combination, and by the minimum unit group of unit energy cost Cooperate the optimal unit combination under the energy supply amount for the second distributed energy resource system.The unit energy cost is second point Fuel cost, start operating cost, start and stop maintenance cost are purchased with outside corresponding to each energy source type in cloth energy resource system The ratio of energy supply total amount of the cost sum with the second distributed system within default research cycle.Wherein, the fuel cost, start Operating cost, start and stop maintenance cost are relevant with the energy supply amount of each energy source type with outside purchase cost.

It can be seen that after above-mentioned steps S803 calculating, any energy that can solve the second distributed energy resource system supplies Corresponding optimal unit combination and unit energy cost should be measured, due to each energy source type of the second distributed energy resource system Energy supply amount is known, so as to also obtain using any scheduling quantum when institute in scheduling interval corresponding to each energy source type Corresponding optimal unit combination and unit energy cost.Therefore, asked when using the upper layer issue in above-mentioned steps S701 to S706 Step is solved, after the scheduling quantum for determining the second distributed energy resource system, the second distributed energy resource system can use above-mentioned determination The scheduling quantum gone out carries out the production of the energy to the fixed Unit Combination of drink.

In the embodiment of the present invention, it is preferred to use particle swarm optimization algorithm solves above-mentioned lower layer problem, or with science and technology Continuous development, if industry proposes the algorithm of other effect of optimization, those skilled in the art also can be according to being actually needed selection Other algorithms are solved, and the present invention is not particularly limited to this.

It should be noted that in the embodiment of the present invention, the second distributed energy resource system can determine it in several ways Whether itself, which participates in, is submitted a tender.A kind of possible implementation is that the second distributed energy resource system is if it is determined that it is distributed for first The scheduling interval of the energy source type of scheduling needed for formula energy resource system is not sky, and the unit energy cost when scheduling quantum is zero is big In default cost threshold value, it is determined that participate in submitting a tender.For the scheduling for the energy source type dispatched needed for the first distributed energy resource system Section is not sky, it is meant that for the energy source type specified, the maximum energy supply amount of the second distributed energy resource system, which is more than, to be worked as Preceding energy supply amount, the second distributed energy resource system have the ability to improve the energy supply amount of itself, and to the first distributed energy Source system provides the energy scheduling of specified type；Unit energy cost when scheduling quantum is zero is more than default cost threshold value Refer to, although the current state of the second distributed energy resource system can reach the equilibrium of supply and demand of itself, the economy of its own Condition is poor, and the unit energy cost in the case of currently not providing the scheduling energy for the first distributed energy resource system is more than it certainly The minimum unit energy cost of body, therefore, the part energy for specifying energy source type is supplied to the first distributed energy resource system, not only The energy output quantity of its own unit can be improved, reduces operating cost, but also can be taken in the fetching portion energy.

Alternatively possible implementation is that the first distributed energy resource system can further wrap in the information on bidding sent The energy total amount of the energy source type of scheduling needed for including, so as to which the second distributed energy resource system can consider the dispatching of itself On the basis of economy condition, further consider whether its current energy supply ability disclosure satisfy that the first distributed energy The energy demand of system, and then determine whether to participate in submitting a tender.

In the embodiment of the present invention, the second distributed energy resource system can also enter if it is determined that participation bid in bid information One step includes each energy source type of its own corresponding supply, transportation quantity, yield and just needs load consumption respectively, with And the potential amount of renewable resource, the information such as renewable resource consumption amount corresponding to each scheduling quantum in scheduling interval, in order to First distributed energy resource system is considered according to these information out of distributed energy network network system entire scope, And determine final energy scheduling and coordinate scheme.

And then in step S703, the first distributed energy resource system, which receives distributed energy network system, includes , can basis after the bid information that the distributed energy resource system that each participation including two distributed energy network systems is submitted a tender is sent The Demand Side Response of scheduling total amount, each distributed energy resource system for participating in submitting a tender needed for its own, the scheduling that can be provided Unit energy cost corresponding to each scheduling quantum in section, the scheduling interval, determine each middle target distributed energy resource system And the scheduling quantum of each middle target distributed energy resource system.

As shown in Figure 10, this process further specifically includes step S1001 to step S1003：

Step S1001：First distributed energy resource system is according to each distributed energy resource system institute energy for participating in submitting a tender The scheduling interval of offer, determine to meet the scheduling total amount requirement, and meet the N kinds energy scheduling side of default sets of constraints Formula；

Step S1002：For any energy scheduling mode in the N kinds energy scheduling mode, described first is distributed Energy resource system is submitted a tender according to the scheduling quantum of each distributed energy resource system for participating in scheduling, participation in any energy scheduling mode The Demand Side Response of each distributed energy resource system, unit energy corresponding to each scheduling quantum in its corresponding scheduling interval Cost is measured, determines the operating cost of the distributed energy network system corresponding to any energy scheduling mode；

Step S1003：First distributed energy resource system is minimum by operating cost in the N kinds energy scheduling mode Scheduling mode is defined as target dispatch mode, and the distributed energy that each participation that the target dispatch mode is included is dispatched System is defined as each middle target distributed energy resource system, by each distributed energy system for participating in scheduling in the target dispatch mode The scheduling quantum of system is defined as the scheduling quantum of each middle target distributed energy resource system.

Specifically, in step S901, the first distributed energy resource system is according to each distributed energy system for participating in submitting a tender The scheduling interval that system can be provided, determine to meet the scheduling total amount requirement, and meet the N kind energy of default sets of constraints Scheduling mode.Wherein, any energy scheduling mode in the N kind energy scheduling modes includes each distributed energy for participating in scheduling The scheduling quantum of source system and each distributed energy resource system for participating in scheduling；N is the integer more than or equal to 1；

For any energy scheduling mode in N kind energy scheduling modes, any energy scheduling mode meets that scheduling is total Amount requirement refers to that the scheduling quantum sum of each distributed energy resource system for participating in scheduling is equal to described in any energy scheduling mode Dispatch total amount.

Any energy scheduling mode meets that default sets of constraints refers to, any energy scheduling mode meets about simultaneously The first constraints and the second constraints in beam condition group.

Wherein, the first constraints is expression using the distributed energy network system after any energy scheduling mode In the energy of each energy source type reach the equilibrium of supply and demand, specifically, first constraints meets equation below：

P_i,sp(t)+P_i,st(t)=P_i,dr(t)+P_i,rc(t)+P_i,ld(t) formula three

Wherein, i is energy source type, and value includes hot and cold, electric, 4 kinds of gas, P_i,sp(t) it is to use any energy scheduling The total supply of i-th kind of energy of distributed energy network system after mode, it is equal to each in any energy scheduling mode Participate in the supply sum of the distributed energy resource system of scheduling, P_i,st(t) it is using described after any energy scheduling mode The accumulating total amount of i-th kind of energy of distributed energy network system, it is equal to each participation scheduling in any energy scheduling mode The transportation quantity sum of distributed energy resource system, P_i,dr(t) it is using the distributed energy after any energy scheduling mode The Demand Side Response total amount of i-th kind of energy of network system, it is equal to each distribution for participating in scheduling in any energy scheduling mode The Demand Side Response amount sum of formula energy resource system, P_i,rc(t) it is using the distributed energy after any energy scheduling mode The recovery total of i-th kind of energy of source network system, it is equal to each distributed energy for participating in scheduling in any energy scheduling mode The yield sum of source system, P_i,ld(t) it is using the distributed energy network system after any energy scheduling mode I-th kind of the firm of the energy needs load total amount consumed, and it is equal to each distributed energy for participating in scheduling in any energy scheduling mode System just needs load consumption sum.

Can be again in the distributed energy network system after second constraints expression use any energy scheduling mode The actual consumption ratio in production-goods source reaches default consumption target, specifically, second constraints meets equation below：

Wherein, η_rFor using renewable resource in the distributed energy network system after any energy scheduling mode Actual consumption ratio, E_reFor using the renewable money of the distributed energy network system after any energy scheduling mode Source dissolves total amount, and it is equal to the renewable resource of each distributed energy resource system for participating in scheduling in any energy scheduling mode and disappeared The amount of receiving sum, E_potFor the potential total amount of renewable resource in the distributed energy network system, it is equal to any energy scheduling The potential amount sum of renewable resource of each distributed energy resource system for participating in scheduling, η in mode_cFor the distributed energy network The default consumption target of renewable resource in system, it can be carried out specifically by those skilled in the art according to actual conditions Set, the present invention is not particularly limited to this.

And then in step S1002, for any energy scheduling mode in the N kinds energy scheduling mode, first point Cloth energy resource system can be according to the scheduling quantum of each distributed energy resource system for participating in scheduling, participation in any energy scheduling mode It is single corresponding to the Demand Side Response of each distributed energy resource system submitted a tender, each scheduling quantum in its corresponding scheduling interval Position cost of energy, by equation below, calculates the distributed energy network system corresponding to any energy scheduling mode Operating cost；

The operating cost in whole distributed energy network system is can be seen that from the formula of above-mentioned calculating operating cost Equal to the cost sum of all distributed energy resource systems in the distributed energy network system, each distributed energy resource system Cost may particularly include energy supply cost, carrying cost, Demand Side Response cost and the class of energy regenerating cost four again.

Specifically, the energy supply cost of any distributed energy resource system is directly related with its energy supply amount, it is equal to each The product of the energy supply amount sum unit energy cost corresponding with the distributed energy resource system of energy source type；Similarly, it is any The carrying cost of distributed energy resource system is directly related with the accumulating supply of its energy, Demand Side Response cost and its Demand-side Response quautity is directly related, and energy regenerating cost is directly related with the yield of its energy, and here is omitted.
