Described generating set refers to the equipment that utilizes natural conditions generating, and for example solar panel utilizes solar power generation, and wind-driven generator utilizes wind-power electricity generation, and power station utilizes the gravitional force generating of water.

Because described generating set is utilized natural conditions generating, so the variation of physical environment can affect the output power of described generating set.Described environmental index refer to the output power of described generating set is played a decisive role environmental factor, the essential environmental factors that for example affects described solar panel output power is sunlight intensity, the essential environmental factors that affects described wind-driven generator output power is wind speed, and the essential environmental factors that affects described power station output power is the flow of water.

Conventionally, obtain generating set output power data and corresponding environmental index data specifically comprise: gather at set intervals once output power and the environmental index of described generating set, continuous acquisition repeatedly simultaneously.The output power of described continuous several times collection is output power data, and the environmental index of described continuous several times collection is environmental index data.

S102, according to generating set output power P described in described generating set output power data and corresponding environmental index data acquisition ^sthe first power function P of relative environmental index W ^s=F ₁(W).

Because the output power of described generating set is mainly determined by described environmental index, therefore can be by the corresponding relation between output power described in the output power data of described generating set and the environmental index data acquisition of correspondence and described environmental index.Described corresponding relation is the first power function.

Due to the generating set output power data of obtaining and corresponding environmental index data normally discrete, therefore can regression analysis obtain described the first power function.

Regression analysis is a kind of common method of Power Systems prediction, its objective is the correlationship of finding between dependent variable (output power) and independent variable (environmental index).According to the relation between independent variable and dependent variable, can be divided into linear regression analysis and nonlinear regression analysis; The number of the independent variable relating to according to regretional analysis, can be divided into simple regression analysis and multiple regression analysis.Regretional analysis ratio juris is utilized known historical data exactly, find out the correlationship between dependent variable and independent variable, set up mathematical model, by least square method, obtain model parameter, then utilize residual error, relative error or absolute error etc. to test to model, when model testing is passed through, can utilize this model to predict power; Otherwise, abandon this model, reselect mathematical model.

For the embodiment of the present invention, described mathematical model is exactly described generating set output power P ^sthe first power function P of relative environmental index W ^s=F ₁(W).

The daytime of described following one day, temperature W can change (being W=E (t)), described solar panel output power P along with the variation of time t ^scan change along with the variation of temperature W (is P ^s=F ₁(W)), therefore can draw described solar panel output power P ^scan change along with the variation of time t.Particularly, the method that can replace by independent variable is obtained described solar panel output power P ^sthe second power function of relative time t, i.e. P ^s=F ₁(E (t))=F ₂(t).

S206, at least continues every D minute, to gather the once electric power of described consumer in one day, obtains the electric power array of described consumer.

Because described objective time interval is following one day, therefore in order to guarantee the accuracy of power consumption control scheme, need to obtain the electric power data that described consumer at least continues a day.

Particularly, at least continue every D minute, to gather the once electric power of described consumer in one day, the electric power of described multi collect is formed to electric power array.

Can gather by each D of method minute of manual record the once electric power of described consumer.Obviously, the data volume of the less collection of described D is more, and follow-up correspondingly processing is also more accurate.

The present embodiment preferably, can access electric energy meter between described consumer and power supply buses, by described electric energy meter, can be realized and every 15 minutes, be gathered an electric power.
