Definitions
- the invention relates to the management of an electrical energy distribution network, by estimating the energy demand by consumers, in particular with the aim of providing for the erasure of targeted consumers (which amounts to imposing maximum consumption on them), limited to a threshold) in case of peak demand.
- a computing entity optimizing the energy supplier in order to optimize the electricity production from its various sources of production (eg nuclear, hydraulic, photovoltaic and / or fossil energy with generator).
- the setting of this model is preferably pessimistic, as indicated, because it is generally taken a safety margin.
- link function When the link function is set, data that can only be intermittently available (from time to time), but not always, is ignored. However, this data may be more recent than parameter data retained and, therefore, provide more relevant information than the parameter data retained.
- the provider is never immune to a computer problem, particularly for the retrieval of the chosen parameter data, which could prevent the model from working effectively.
- the present invention improves the situation.
- the link function chosen for the model applied in step c) is adaptive and depends on the parameter values received in step b).
- Steps a) and b) include in particular the operations:
- step b2) determining, according to a chosen criterion, a ranking in order of relevance of the parameters whose values are received in step b1), and
- step c) constructing a model based on at least one link function involving at least one of the most relevant parameters according to the classification of the operation b2), for the subsequent implementation of step c).
- the link function used is not fixed, but it is adaptive according to the most promising parameters for the prediction to be made.
- the aforementioned criterion has at least one component relating to the novelty of a value received for one parameter, relative to other values received for other parameters.
- the above-mentioned chosen criterion may be unique or, in a more sophisticated variant, result from a combination of several criteria.
- the criterion chosen may also take into account a planned date for estimating the energy demand.
- the model constructed in operation a2) is based on an average of link functions (and thus results from an average of models) each involving at least one parameter among the most relevant parameters according to the ranking of operation b2).
- this average is a weighted average according to the order of relevance of the parameters determined in the operation b2).
- the ranking in order of relevance of the parameters is done by calculating more precisely the relevance of the models using these parameters.
- the operation b2) then comprises:
- the error for each model is preferably estimated by comparing:
- the models of the plurality of models are constructed by learning in a received parameter value history database.
- the method may then comprise a target erection step d) of targeted consumers, in case of prediction of a peak demand in step c).
- the invention also relates to a computer program (the general algorithm of which may correspond to FIG. 4) and comprising instructions for the implementation of the above method, when this program is executed by a processor.
- the present invention also relates to a computing device (reference SI of Figure 1 discussed below) for managing an electric power distribution network, and implementing an estimate of energy demand by consumers.
- This device comprises in particular a processing circuit including a processor (reference PROC of Figure 1) for the implementation of the method above.
- FIG. 1 illustrates a global system comprising the computing device SI for the implementation of the present invention
- FIG. 2 illustrates more precisely the operation of the computing device SI
- FIG. 3 illustrates the adaptation of the data in history for a particular update
- FIG. 4 illustrates the main steps of a method in a particular embodiment of the invention.
- the computing device SI (for "information system") is presented in the form of a computer typically comprising a computer processing circuit including:
- an input interface IN to receive historical data to be stored, and to process to establish models by self-learning
- a memory MEM2 for storing these data in a database BD history
- a working memory MEM cooperating with the processor PROC for the processing of these data, this memory being able to store further instructions of a computer program within the meaning of the invention
- an output interface OUT for example to send an erasure instruction calculated by the computing device SI, as a function of the processing of the received data.
- the input data IN can be received via an NW network. It can be typically:
- HRD power consumed for example
- the output data OUT can be sent via the NW network and can correspond to:
- a self-learning solution is set up so that when new data arrives, the model relearns the actual parameters of the model.
- the data used for forecasting often come from individual meters (for example, from companies).
- An imponderable thing about this approach is that the data recovery time remains random. However, it appeared that the more recent data used in the model, the better the forecast.
- a self-learning solution where the parameters of the model are regularly updated with the arrival of new data is proposed here.
- the link function that is the basis of the definition of the model is not definitively fixed, but it is adaptive according to the most recent data received.
- the invention makes it possible to always make a prediction even in the case where data recovery is not possible.
- the forecast is not simply realized using a single model, but using several models where the final forecast is a weighted average of the together model forecasts, the weight of a model being all the more important as its latest forecasts are better.
- it seeks to predict the erasure of consumers having a consumption contract greater than 250 kW and adhering to an offer with a tariff incentive to erase on a general peak day.
- the data recorded in individual counters 1 to n are read remotely by the supplier and then stored in a database BD.
- the data is then corrected (for obvious errors) and aggregated.
- a file of the available data history is then generated. This file includes the polling date, the aggregated power of the portfolio, and the deletion indication.
- This file with the desired start and end dates, is provided to a self-learning module.
- the self-learning module adjusts the link function of each prediction model according to the data, learns the parameters and makes the prediction on dates passed as parameters.
- the prediction is written by the module in an output file which is then read by the computing device SI.
- the prediction can then be transmitted to an erasure optimizer for example (not shown).
- the module therefore builds one or more models where the most recent variable ("delayed power” here) is delayed by Delta. It should be noted that it is possible to provide several delayed variables as explanatory variables of the model, possibly different from a delayed power.
- the first step is the calculation of Delta in step S1.
- the module in order to learn the parameters of these link functions, the module generates a learning database from which the parameters of the N models are learned (step S2).
- a prediction is then made from each model for N models from 1 to N (step S3).
- the applied prediction is simply an arithmetic mean of all the predictions of the N models (step S5).
- a weighted average based on the error made by the N models on the last predictions is rather calculated (step S6).
- a consumption model (and the associated link function) using yesterday's meteorological data would have less weight than a trend model. consumption and using consumption data collected from consumers at a pace of 20 minutes for example. On the other hand, the receipt of more recent meteorological data could reverse this weighting.
- the second criterion presented above if a prediction has already been made for the type of day on which the prediction must be made (for example a Monday, or a Tuesday, ...) and a type of instant (for example at 8h, or 8h30, ...) (T7 test of Figure 4), the final prediction is:
- step S8 the weighted average of the predictions of the N models (step S8), or the prediction of one of the N models if this model is more efficient for the type of time of day and type of day than the prediction by weighted average (step S9).
- step S 8 the weighted average prediction is used (step S 8).
