Technical scheme in the embodiment of the present application is solve above-mentioned technical matters, and general thought is as follows:

Provide a kind of consumer defining method, be applied in a multiple load system, the consumer of at least two class power brackets is comprised in described multiple load system, described method comprises: when described multiple load system is in multiple different steady state (SS), is in the consumer quantity of opening under determining each steady state (SS) in every class power bracket; Based on described consumer quantity, determine that consumer is in the total degree of opening under every class power bracket; The ratio of the consumer obtained in each power bracket is calculated based on described total degree; Based on the ratio of described consumer and the total quantity of described consumer, determine the quantity of the consumer that each power bracket comprises in described multiple load system.Thus reach the technique effect of the quantity accurately can determining the consumer that each class power bracket comprises in multiple load system, and then the precision of load decomposition can be improved.

In order to better understand technique scheme, below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail, the specific features being to be understood that in the embodiment of the present invention and embodiment is the detailed description to technical solution of the present invention, instead of the restriction to technical solution of the present invention, when not conflicting, the technical characteristic in the embodiment of the present invention and embodiment can combine mutually.

First aspect, the embodiment of the present invention provides a kind of consumer defining method, is applied in a multiple load system, and comprise the consumer of at least two class power brackets in described multiple load system, please refer to Fig. 1, described method comprises:

Step S101: when described multiple load system is in multiple different steady state (SS), is in the consumer quantity of opening in every class power bracket under determining each steady state (SS);

Step S102: based on described consumer quantity, determines that consumer is in the total degree of opening under every class power bracket;

Step S103: the ratio calculating the consumer obtained in each power bracket based on described total degree;

Step S104: based on the ratio of described consumer and the total quantity of described consumer, determine the quantity of the consumer that each power bracket comprises in described multiple load system.

For example, consumer in multiple load system can be divided into four class power brackets, be specially: other consumers (<300w), miniwatt consumer (300w ~ 700w), middle power consumer (700w-1500w), large power-consuming equipment (>1500w), consumer can certainly be divided into other power brackets, this embodiment of the present invention is no longer itemized, and is not restricted.

Steady state (SS) in step S101 refers to the opening and closing action not having consumer within certain period, and consumed power value keeps stablizing the constant time period.

In step S101, the changed power curve of multiple load system can be obtained, this changed power curve characterizes the general power of this multiple load system at different time, then, the value of itself and adjacent sampled point can be compared for sampled point each in changed power curve, if differ by more than predetermined threshold value, the power generation cataclysm of this sampled point is then described, such as: certain load equipment enters closed condition by opening, or certain load equipment enters opening etc. by closed condition, and then this point is defined as power samples point, then each power adopts point can to should multiple load system steady state (SS).

Wherein, all consumers that can control multiple load system in the starting stage are all in closed condition, then, power variation D (k) between acquisition adjacent stable state=| P (k)-P (k-1) |, and then determine the power of the consumer being in opening, and D (k) is divided into each classification, such as: if at a time, power recruitment D (k)=500W, then illustrate in this system and open a low-power electrical device; If at a time, power reduction D (k)=500W, then illustrate in this system and close a low-power electrical device; And then by the power cataclysm value of multiple power samples point, just can determine that different capacity consumer opens and closes number of times.

In step S102, can by under each steady state (SS), the state change frequency that the consumer of unlatching or closing motion occurs sums up, and then obtains the total degree of consumer state change.

Such as, suppose that sampling altogether obtains power cataclysm value D (k) of multiple load system at 30 power samples points, the consumer quantity that D (k) is in each power bracket is as shown in table 1, and can obtain consumer state change total degree is 30.

Table 1

Device category	Other	Miniwatt	Middle power	High-power
					Quantity	4	10	6	10

Wherein, k _jrepresent that the consumer of jth power bracket is in the total degree of unlatching or closed condition;

K represents that all consumers are in the total degree of unlatching or closed condition.

And then it is as follows to calculate the ratio of consumer under every class power bracket:

The ratio of other consumers is: 4/ (4+10+7+9)=4/30

The ratio of miniwatt consumer is: 10/30

The ratio of middle power consumer is: 6/30

The ratio of large power-consuming equipment is: 10/30

In step S104, the quantity of the consumer that each power bracket comprises can be determined by following formula:

$n_j=\left[N\frac{k_j}{K}\right]\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\left[2\right]$

Wherein, n _jrepresent the quantity of the consumer comprised in jth power bracket;

N represents the total quantity of described consumer;

represent the ratio of the consumer of jth power bracket kind.

Wherein, the total quantity of consumer can be inputted by the system user of multi-load, suppose the total quantity of consumer be 15 (certain, can also be other values, the embodiment of the present invention is not restricted), then the quantity that can calculate the consumer that each power bracket comprises is as follows:

The quantity of other consumers is: [4/30*15]=2

The quantity of miniwatt consumer is: [10/30*15]=5

The quantity of middle power consumer is: [6/30*15]=3

Wherein, be located in observation time and co-exist in K stable state, the general power of each stable state is P (k), and initial time is S (k), and the duration is T (k), and so in a kth stable state, formula [3] can be write as following formula:

$P\left(k\right)=\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{a}_i\left(k\right)p_i\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\left[4\right]$

Wherein, $P\left(k\right)=\frac{1}{T\left(k\right)}{\&Integral;}_{S\left(k\right)}^{S\left(k\right)+T\left(k\right)}P\left(t\right)\mathrm{dt}\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\&CenterDot;\left[5\right]$
