Step 101: obtain load control priority and load control total amount that supply side generates, and according to described load control priority, the highest load control mode of priority is defined as when preload control mode, described load is controlled to total amount and be defined as controlling total amount when preload.

User participate in loading control item object mode can have multiple, for example: control that direct load is controlled, interruptible load is controlled and demand is bidded.Certainly, described load control mode, including but not limited to above-mentioned one or more modes, is used the load control form of electric power all in the application's protection domain so long as can be used for cutting down user's side load equipment.

Supply side can assumed load control mode according to power shortage situation priority, it is any one in described load control mode permutation and combination result that described load is controlled priority, for preferentially choosing the user with certain load control mode.According to described priority, the highest load control mode of priority is defined as when preload control mode, in order to choose there is described load control mode user as alternative user.For example, direct load control mode is made as to A, interruptible load control mode is made as to B, the demand control mode of bidding is made as to C, described load is controlled priority and be can be CBA, chooses C and is demand and bid control mode for when preload control mode.

When there is the situation of power supply shortage, in order to alleviate with Voltage force, supply side generates the demand of loading and controlling, and wherein, includes load and controls total amount, in order to represent described electric power breach situation in described demand.For example, 1000 watts.Described load is controlled to total amount to be defined as controlling total amount when preload.

Step 102: according to default screening conditions, will be defined as current alternative user as the corresponding user of preload control mode with described; Wherein, described current alternative user is a plurality of.

User participates in described load and controls project, need apply in advance, and submit to the described load of participation to control required information to supply side.Described informational needs is preserved, and the form of preservation can have multiple.Preferably, set up in advance load resources bank, the load control information that includes user in described load resources bank, described load control information includes but not limited to the following: the device name of user ID, user's name, station address, user's contact method, participation, load control mode, load controlled quentity controlled variable, the from date of participation, the date of expiry of participation, notice time, carry out duration, compensation account form, penalty for nonperformance of contract account form, can participate in number of times, credit worthiness, participation period and/or participation method.

From described load resources bank, obtain successively each user's load control mode, choose with described when the identical user of preload control mode is as current alternative user.For example, when preload control mode is the demand control mode of bidding, choosing load control mode and be the bid user of control mode of demand is current alternative user, and described alternative user's number is a plurality of, for example: described alternative user is 100.

Step 103: obtain the described corresponding load controlled quentity controlled variable of each current alternative user.

In described load resources bank, obtain the described corresponding load controlled quentity controlled variable of each current alternative user, for example: 100 current alternative users are user 1,2,3 ... 100, obtain successively described user 1 to 100 load controlled quentity controlled variable separately, if user 1 load controlled quentity controlled variable is 10 watts, user 2 load controlled quentity controlled variable is 20 watts.

Step 104: when described each load controlled quentity controlled variable sum is more than or equal to describedly when preload is controlled total amount, according to default constraint condition, apply default optimization partition function, definite targeted customer in described each current alternative user; Wherein, described optimization partition function comprises grid loss revenue function, the influenced range function of user and/or load control Validity Function.

Each the current alternative user's who obtains in step 103 load controlled quentity controlled variable sum is more than or equal to described when preload is controlled total amount, for example, described current alternative user's 1 to 100 load controlled quentity controlled variable sum is 2000 watts, described when preload, to control total amount be 1000 watts, and in described each current alternative user, select target user is used for participating in described load and controls project.

Described default constraint condition can be the constraint condition generating according to the load controlled quentity controlled variable of supply side generation and safe operation of electric network situation, comprises load power ratio control constraint condition and electric power safety operation constraint condition.Wherein, described load power ratio control constraint condition refers to that customer charge controlled quentity controlled variable sum meets load and controls total amount requirement; The constraint condition of described electric power safety operation, the electric weight that finger user cuts down in load control time will meet the safety requirements of electric power slippage, if in the situation that user carries out translation or transfer by the electricity consumption period, the electric weight that the period user in translation or after shifting increases also will meet translation or shift the safety requirements of rear corresponding electric power recruitment.Described electric power safety operation constraint condition is in order to guarantee grid equipment safety, as line security.

According to optimizing partition function, utilize default algorithm, as enumeration, genetic algorithm etc., described alternative user, concentrate and determine targeted customer.Certainly, described preset algorithm is not limited to the above-mentioned algorithm of enumerating, so long as can be at the algorithm of alternative concentrated select target value all in the protection domain in the application.

It should be noted that, optimizing partition function can be one or more in grid loss revenue function, the influenced range function of user, load control Validity Function.When described majorized function is grid loss revenue function, the alternative user when making grid loss income be minimum value is defined as targeted customer.When described majorized function is the influenced range function of user, the alternative user when making the influenced scope of user be minimum value is defined as targeted customer.When described majorized function is controlled Validity Function for load, by making load control the alternative user of validity preferably time, be defined as targeted customer.Wherein, described load control Validity Function be user credit worthiness and value, described load is controlled the credit worthiness sum maximum that validity preferably refers to user.Certainly, described alternative user comes from the alternative user who determines in described step S102.

When described optimization partition function comprises that grid loss revenue function, the influenced range function of user, load are controlled Validity Function simultaneously, described optimization partition function is multiple objective function, described grid loss revenue function, the influenced range function of user, load are controlled Validity Function and are respectively sub-goal, according to the weight coefficient of described three sub-goals that obtain (described three weight coefficients add up to 1), the targeted customer in the time of can obtaining making grid loss income, the influenced scope of user and load control validity account for any weight separately.

As, the weight coefficient of described grid loss income is 0.8, the weight coefficient of the influenced scope of user is 0.1, the weight coefficient that load is controlled validity is 0.1, the targeted customer who determines according to described weight coefficient, can realize and consider a little, on the basis of the influenced scope of user and load control validity, to guarantee that grid loss income is as far as possible few.

For another, the weight coefficient of described grid loss income is 0.1, the weight coefficient of the influenced scope of user is 0.8, the weight coefficient that load is controlled validity is 0.1, the targeted customer who determines according to described weight coefficient, can realize and consider a little, on the basis of grid loss income and load control validity, to guarantee that user's participation number is as far as possible few.

And for example, the weight coefficient of described grid loss income is 0.1, the weight coefficient of the influenced scope of user is 0.1, the weight coefficient that load is controlled validity is 0.8, the targeted customer who determines according to described weight coefficient, can realize on the basis of participation number of considering a little grid loss income and user, the control validity that guarantees to load is tried one's best.

For another example, the weight coefficient of described grid loss income is 0.3, the weight coefficient of the influenced scope of user is 0.3, the weight coefficient that load is controlled validity is 0.4, the targeted customer who determines according to described weight coefficient can guarantee the grid loss income of trying one's best few, the influenced scope of few user of trying one's best and to the greatest extent measured load control validity simultaneously.

It should be noted that, described each weight coefficient can be default fixed value, can be also the input value of obtaining.When being the input value of obtaining, can realizing according to different demands different optimization and distribute target.

From above technical scheme, the present embodiment provides a kind of load of power industry to control distribution method, the method comprises, obtain load control priority and load control total amount that supply side generates, and according to described load control priority, the highest load control mode of priority is defined as when preload control mode, described load is controlled to total amount and be defined as controlling total amount when preload; According to default screening conditions, will be defined as current alternative user as the corresponding user of preload control mode with described; Obtain the described corresponding load controlled quentity controlled variable of each current alternative user; When described each load controlled quentity controlled variable sum is more than or equal to describedly when preload is controlled total amount, according to default constraint condition, apply default optimization partition function, definite targeted customer in described each current alternative user; Wherein, described optimization partition function comprises grid loss revenue function, the influenced range function of user and/or load control Validity Function.

Because user's number is when more than enough, the user that load control mode is limit priority is also abundant, the alternative user who determines also enough meets the condition that load is controlled total amount, described a plurality of alternative user can jointly participate in described load and control project, if but common participation can cause user in a big way influenced, and cause electrical network income to be subject to larger loss due to participating user is compensated.Wherein, described optimization partition function can be the one or more combination in grid loss revenue function, the influenced range function of user, load control Validity Function, thereby can control under the prerequisite of total amount and load control security meeting load, the load of realize simultaneously and try one's best supply side grid loss income little, try one's best the influenced scope of little user, trying one's best high is controlled three of validity and is optimized one or more in sub-goals.

In addition, when majorized function target comprises a plurality of sub-goal, by obtaining the weight coefficient value of each sub-goal of input, according to different actual demands, set up different optimization partition functions.Utilize described each different optimization partition function to realize different optimization aim, realize load and control the dirigibility that distributes target.

When if power tense situation is severeer, it is larger that the load that supply side generates is controlled total amount, the current alternative user in embodiment mono-is not enough to meet the requirement that described load is controlled total amount, needs to control priority according to described load and determines each targeted customer that the described load of participation is controlled.Refer to Fig. 2, a kind of power industry load that it shows the application provides is controlled the process flow diagram of distribution method embodiment bis-, and the present embodiment can comprise:

equal corresponding load controlled quentity controlled variable value (represent to cut down or consume by sign, cut down load for just, consume load for negative), otherwise

If in described step S201, determine when preload control mode be the demand load control mode of bidding, the corresponding load controlled quentity controlled variable of each current alternative user that the demand of obtaining is bidded and loaded under control mode, whether described each load controlled quentity controlled variable sum of judgement is more than or equal to the described preload of working as is controlled total amount.After each current alternative user that demand is bidded under control mode levies by above-mentioned time series table, judgment rule is:

$\underset{i=1}{\overset{N_{\mathrm{DSB}\_\mathrm{act}}}{\mathrm{\Σ}}}{P}^i\left(t\right)\≥\mathrm{EP}\left(t\right),t=\mathrm{1,2}...48,$ Wherein: described in

for demand load each current alternative user under control mode each load controlled quentity controlled variable sum in the t time period of bidding; Described EP (t) is that the load of t time period is controlled total amount.

Table 1 for example, t is that to control total amount EP (t) be 1000 watts to 23 o'clock loads.Table 2 for example, t is that the load controlled quentity controlled variable of 23 o'clock current alternative user C1, C2 and C3 is respectively 100 watts, 150 watts and 200 watts, each current alternative user is in each load controlled quentity controlled variable sum of t time period

for 450 watts of 100+150+200.Therefore, t is 23 o'clock, and described judgment rule is also false, and represents describedly to judge whether each load controlled quentity controlled variable sum is more than or equal to that described the determination result is NO when preload is controlled total amount.If by t in table 1 be 23 o'clock loads to control total amount EP (t) be 300 watts, described judgment rule is set up, and represents describedly to judge whether each load controlled quentity controlled variable sum is more than or equal to and describedly when preload, control judgment result is that of total amount and be.

Step S205: if so,, according to default constraint condition, apply default optimization partition function, determine in described each current alternative user and targeted customer enter step S209; Wherein, described optimization partition function comprises grid loss revenue function, the influenced range function of user and/or load control Validity Function.

It should be noted that, the step S104 in described embodiment mono-is last step of embodiment mono-, and step S205 is identical with the content of step S104, but step S205 following step is step S209.

Step S206: if not, described each current alternative user is defined as to targeted customer, controls priority according to described load and determine when preload control mode.

Load controlled quentity controlled variable sum in each current alternative user in this step is less than or equal to described when preload control total amount,, there is the described alternative user when preload control mode and be not enough to meet the described requirement that preload is controlled total amount of working as, described each current alternative use is defined as per family finally participating in described load control item object targeted customer, and with load controlled quentity controlled variable separately, participates in described load and control project.For example, when preload control mode is that C is the demand control mode of bidding, have demand bid control mode alternative user 1 to 100 each load controlled quentity controlled variable be 5 watts, the controlled quentity controlled variable of loading sum is 500 watts, be less than described when 1000 watts of preload control total amounts, described current alternative user 1 to 100 is all defined as to targeted customer, the load controlled quentity controlled variable of 5 watts is provided separately.

According to the described load obtaining in step S201, control priority load control mode for when preload control mode, for example, it is CBA that described load is controlled priority, when preload control mode is C, new when preload control mode be B; If that work as preload control mode is A, the new preload control mode of working as is empty.

Step S207: judge whether to exist when preload control mode.

Judge whether to exist when preload control mode, judge whether all users all to screen, in the present embodiment, circulate and choose the end condition of current alternative user procedures.

Step S208: if so, control total amount by described value deducting after described each load controlled quentity controlled variable sum when preload control total amount as the new preload of working as, and enter step S202.

If exist, new when preload control mode, in the user with described new load control mode, select new current alternative user, and according to default optimization partition function, determine targeted customer in described new current alternative user.For example, new when preload control mode be B, it is interruptible load control mode, in described step S204 t be 23 o'clock when preload, to control total amount be 1000 watts, t is that each load controlled quentity controlled variable sum of 23 o'clock is 450 watts, with 1000 watts, deducting 450 watts of surpluses is 550 watts, as new, controls total amount when preload using described remaining 550 watts, and reenters step S202.

Step S209: if not, all described targeted customer who determines is merged into final targeted customer.

If do not exist new for preload control mode, for example, new when preload control mode be empty, represent that circulation chooses described targeted customer's process and meet cut-off condition, each targeted customer definite in described step S205 and step S206 is merged as final targeted customer.

From above technical scheme, the present embodiment provides a kind of power industry load to control distribution method.If when the situation of described supply side power tense is more serious, may generate larger load and control total amount, the control mode that causes loading is the demand that load controlled quentity controlled variable that maximum load is controlled the alternative user of priority can not meet described supply side.The described load generating according to described supply side in the method that the present embodiment provides is controlled priority, the current alternative user who does not meet current load control total amount is defined as to targeted customer, upgrade described when preload control mode, and in thering is the alternative user of new current control mode, determine targeted customer, until do not exist new load control mode or described current alternative user's load controlled quentity controlled variable sum to be enough to meet when the requirement of preload control total amount, thereby at supply side, generate larger during when load control total amount, provide a kind of load to control allocative decision, the targeted customer who determines participates in described load and controls project.
