According to step S200, the related data information of acquisition meets the steady working condition of system, determines the stabilization of the system
Working condition be include:
Coordinated control system investment is automatic, and each subsystem operates normally;
Whithin a period of time, the stabilization of the actual load and main steam pressure of the actual load of power grid and power and unit
Property index meets defined threshold.
Wherein there is a condition undesirable, then the time opposite bank up time recursion of books sampling, until meeting set
Two conditions, i.e., for guarantee information collected be in the case where system run all right, can avoid acquisition data go out
Existing biggish fluctuation, and lead to occur biggish error when subsequent evaluation, it can effectively improve the precision of its evaluation
For stable state decision threshold formula are as follows:
In formula, AmaxAnd AminThe maximum value and minimum value of certain parameter respectively in a period of time, Ae are the parameter specified
Rated value under load, δkFor stable threshold.
When carrying out stable state detection, operating parameter, boundary constraint and each correlated characteristic variable are comprehensively considered to system performance
Influence degree select stable state to determine characteristic variable, carry out quasi-steady state processing for fluctuating biggish data, i.e., will collect
Data sample carry out mean value computation whithin a period of time, the length of period is according to the characteristic variable inertia of related system come really
It is fixed, and obtained steady state condition point data sample is stored in steady running condition database.
According to step S200, data preprocessing method the following steps are included:
Step S201 carries out stable state detection to data and quasi-steady state is handled;
Step S202, to treated, data carry out cleaning and validation verification, complete the secondary treatment of data;
Step S203 is standardized conversion to the data after secondary treatment, completes data prediction.
The processing method of the data cleansing and validation verification includes: missing values processing and noise filtering.
Missing values processing includes elimination method and interpolation.
Elimination method is big for sample size and missing values shared by sample ratio it is smaller when, the ratio that missing values account for sample does not surpass
5% is crossed, the accuracy of data after handling with guarantee.
The thought source of interpolation is to carry out interpolation missing values with most likely value, and there are commonly following several methods:
Mean value interpolation can split data into spacing type and non-spacing type according to the attribute of data.If missing values are spacings
Type, the value of interpolation missing is just carried out with the average value of the attribute existence value;If missing values are non-spacing types, just according to statistics
Mode principle in, the value lacked with the mode (i.e. the highest value of the frequency of occurrences) of the attribute come polishing;If data fit
Compared with the regularity of distribution of specification, then intermediate value interpolation can also be used.
Regression imputation, i.e., using the data that linearly or nonlinearly regression technique obtains come the missing data to some variable into
Row interpolation.
Maximum-likelihood estimation, under conditions of deletion type is missing at random, it is assumed that model is just for complete sample
True, then the limit distribution by observation data can carry out Maximum-likelihood estimation to unknown parameter, this method is also claimed
For the Maximum-likelihood estimation for ignoring missing values, for maximum likelihood parameter Estimation in practice frequently with calculation method be expectation
Value maximizes, and than deleting case and monodrome interpolation more attractive, its important prerequisite is this method: being suitable for full-page proof
This.
Noise is data random error present in data.Common noise filtering methods have the Return Law, mean value smoothing
Method, the point analysis that peels off etc..
The Return Law is with a Function Fitting data come smooth data.First data are visualized, judge becoming for data
Then gesture and rule determine whether to be denoised with the Return Law again.
Mean value smoothing method refer to the variable with sequence signature is replaced with the mean value for several data closed on it is original
The method of data.
The point analysis that peels off is to detect outlier by the methods of cluster, and be deleted, thus the method for realizing denoising.
In addition, the thermodynamic behaviour change of unit and energy storage device causes for amendment as system operation time elapses
Aging, according to the validity of the preliminary Identification Data sample of the time tag of system operation data sample, with the overhaul week of system
On the basis of phase, have to acquisition from the history data in the same overhaul life in conjunction with literary data actual effect factor calculation method
The verifying of effect property.
According to step S203, the data normalization conversion formula are as follows:
In formula, x 'ijFor the index value after standardization, xijFor j-th of index value of i-th of scheme,For j-th of index
Minimum value,It is described for the maximum value of j-th of indexWithAcquisition modes include two kinds, and one is vertical by search
Formula operation data library obtains, secondly being determined according to Related Mechanism analysis.
Standardization conversion for data, is to be standardized to raw measurement data, by different characteristic variable
Attribute value be converted in [0,1] section, to achieve the purpose that improve arithmetic accuracy and computational stability.
The power distribution network coordinated scheduling evaluation criterion weight method of determination of the meter and energy storage are as follows: using based on game theory
Combination weights method combines the subjective weight determined by analytic hierarchy process (AHP) with the objective weight determined by entropy assessment, and obtaining can
The comprehensive weight of the renewable sources of energy and energy storage coordinated scheduling evaluation index.
According to step S400, using fuzzy synthetic appraisement method to the economy of coordinated scheduling scheme, the feature of environmental protection and reliable
Property complete overall merit method the following steps are included:
Step S401 sets Comment gathers V={ V1,V2,V3,V4,V5, and the index subset evaluated is determined according to Criterion Attribute
Ui={ Ui1,Ui2,…,Uik};
Step S402 further determines that the weight A of each index according to the index set of evaluation is determinedi=[ωi1,
ωi2,…,ωij];
Step S403;Level-one fuzzy overall evaluation is completed according to weight and evaluation;
Step S404;Two-level appraisement is carried out according to level-one fuzzy overall evaluation result;
Step S405, repeats step S402 to step S404, completes to the economy of coordinated scheduling scheme, the feature of environmental protection and can
Overall merit is completed by property.
The Comment gathers include poor, poor, general, more excellent and excellent five grades, respectively correspond V1、V2、V3、V4And V5, i.e.,
Evaluate collection is V={ V1,V2,V3,V4,V5, what the various evaluation results for indicating that different scheduling schemes may be made formed
Set, each comment value indicate corresponding index or index subset to the degree of membership of the comment, and the determination of Comment gathers result can be with
