- pre-recorded correspond to electrical power values
- This database 30 includes for each day of the year and for different times of each day photovoltaic power values generated as a function of irradiance.
- this database 30 comprises on ordinates 32 in steps of 10 W / m 2, for example irradiance levels.
- the irradiance values range from 0 to 1300 W / m 2 , in this case between 0 and 1100 W / m 2 . This range of levels seems sufficient, because in general, the irradiance of a normal surface to direct sunlight is at most around 1000 W / m 2 .
- each day of the year is present in the table of the database 30 (January 1 (01/01) December 31 (31/12)), for each day, different times listed by one hour are listed, for example twenty-four times ranging from 00: 00h to 23: 00h in intervals of one hour.

- [110] - P1 corresponds to the photovoltaic power 36 generated for a
- [111] - Ee corresponds to a predicted value of irradiance 32.
- [119] - P2 corresponds to the photovoltaic power generated at a time
- the corrections in this case are linear, they can be made first at the level of irradiance and then at the intra-interval time or in the reverse order.
- the pre-recorded digital values correspond to coefficients of a mathematical function, in particular a polynomial function, for example of degree 4, describing values of electric power generated as a function of the irradiance in a range of irradiance values between 0 and 1300 W / m 2 .
- this database 30 comprises for each day of the year and for different times of each day a set of coefficients, for example A, B, C, D, E making it possible to calculate PV power values generated as a function of irradiance using a mathematical function.
- this method does not require an irradiance interpolation calculation to process a precise level of irradiance.
- to evaluate the power at 10:15 a.m. under a GHI irradiance of 468 W / m 2 to evaluate the power at 10:15 a.m. under a GHI irradiance of 468 W / m 2 .
- the photovoltaic production of the power generation unit 12 can be evaluated at any time of the year and for all irradiance conditions with precision.
- Block B1 represents the modeling of the energy supply installation 11 and in particular the electricity production unit 12 as a whole beforehand and block 2 represents a program of dimensioning or simulation known from the prior art such as the commercial products PVSYST, PVSOL or academic SAM or collaborative LADYBUG. Such a model takes into account a multitude of parameters such as in particular the characteristics of the photovoltaic modules 14, their location / orientation / inclination on site 1 and their number and efficiency.
- the modeling also includes the description of the wiring of the various photovoltaic modules 14 together, or the description of the power conversion equipment (inverters, controllers, transformers, etc.) used for example.
- FIG. 7 shows an embodiment of a method for evaluating the production of photovoltaic energy for the energy supply installation 11 located on site 1.
- This step E1 is carried out in particular by supplying the irradiance values by the meteorological evaluation system 28 to the evaluation and management unit 16 using telecommunication means 26.
- the determination of irradiance and other meteorological parameters is carried out for forecast time intervals of between one second and two days, in particular less than 5 min. It is clear that the shorter the forecast time interval, the more reliable the forecast of irradiance values. Then the step between two forecasts of irradiance values can be chosen as required, for example a forecast every 10 s in the case of the management of a local network 22 as will be explained below.
- the meteorological parameters collected can span intervals ranging from a few minutes to a few days.
- the determination (prediction or collection) of meteorological parameters over a given forecast time interval is defined over a time step less than or equal to the forecast time interval typically given between one second and a few hours.
- the photovoltaic power generated is evaluated according to the determined irradiance values, the time point in the year of this evaluation and the generated power values pre-recorded 36 in the database 30. by simple reading or by calculation using the mathematical function and the coefficients as has been detailed above for the two embodiments, as the case may be by carrying out linear interpolations for the irradiance 32 or the instant in the year 34.
- a step is carried out for correcting the prerecorded values 36 in the database 30 of the photovoltaic power generated by taking account of predictive, past or measured values of the temperature (in particular temperature of the modules 14 or ambient temperature on site 1) and / or the wind speed on site 1 of installation by applying a correction coefficient, in particular linear.
- the photovoltaic modules 14 and particularly the cells which compose them are the components whose conversion efficiency
- Photovoltaic is linked almost linearly to the operating temperature of the cells. Secondly, ambient temperature can limit the conversion efficiency of energy converters such as inverters.
- the temperature can therefore for example be determined using a temperature sensor attached to a module 14 and connected to the evaluation and management unit 16 or be the result of weather forecast calculations transmitted by the meteorological rating system 28.
- linear interpolation can also be used as a first approximation to refine the calculations.
- a database 30 for example in the form of a table, in order to determine the past or future theoretical photovoltaic power 36 generated by the electricity production unit 12 by simple determination ( predictive or historical collection) of irradiance makes it possible to limit the necessary computing powers to the strict minimum.
- the use of such a database 30 makes it possible to facilitate calculations and therefore allows a simpler and faster determination of the photovoltaic power 36 generated by the energy supply installation 11 at any time of the day. and the year.
- Use of this database 30 allows an almost instantaneous evaluation of the electrical power generated, which is not possible with the sizing programs known from the prior art.
- fine sampling less than or equal to 5 minutes, and in particular every minute.
- the valuation calculations can also be done on a physical machine or a virtual machine on the cloud computing which is not always possible with for example commercial photovoltaic sizing software.
- FIG. 8 shows an embodiment of a method for forecasting the production of photovoltaic energy and for managing electrical appliances which is for example implemented by the evaluation and management unit 16 for management of the local electricity network 22.
- step F1 which is similar to step E1 in FIG. 7, predictive meteorological parameters (irradiance value, temperature on site 1, wind speed on site 1 for example) are collected for site 1 where the energy supply installation 11 is located.
- Parameter values are collected for site 1 where the energy supply installation 11 is located.
- the evaluation and management unit 16 is configured to control the local electrical network 22 according to the forecast of the photovoltaic energy production of the energy supply installation 11. .
- This control of the local electrical network may include one or more of the following actions in the non-exhaustive list, for example:
- step G1 which is similar to step E1 in FIG. 7, historical meteorological parameters are collected (irradiance value, temperature on site 1, wind speed on site 1 for example) for site 1 where the energy supply installation 11 is located. Parameter values
- these historical values can be provided by sensors of site 1 and recorded for example in a memory of the evaluation and management unit 16.
- steps E2 and E3 follow (E3 being optional) as described above in relation to FIG. 7. These steps E2 and E3 therefore make it possible to provide a reference value that the energy supply installation 11 would have. had to be produced depending on the irradiance and possibly the temperature.
- the evaluation and management unit 16 is configured to compare the photovoltaic energy production evaluated on the basis of the historical meteorological values with the actual photovoltaic production measured during a past time interval.
- the evaluation and management unit 16 is configured to generate an alert if the difference between the energy production
- PV evaluated and PV production measured during the elapsed time interval is above a predefined threshold.
- the measured value is significantly lower than the theoretical value (for example 10%), it can be deduced that the energy supply installation 11 is subject to a malfunction such as the presence of dust or dirt on the photovoltaic modules 14, a fault in the chain of modules 14 etc. requiring maintenance.
- Historical meteorological parameters can be collected with great precision and / or with a large amount of data. A more detailed evaluation of the theoretical power over time or else an evaluation over a longer time interval is therefore possible with the same computing power.
- one of the determining aspects of the present invention lies in the use of a database 30 and in the choice of how this database 30 is organized in order to make it possible to evaluate the production of electricity with pre-recorded digital values making it possible to determine the specific photovoltaic power of installation 11 on site 1 and from a few variables such as a time of year for example (date + time making it possible to take into account the aspects astronomical and geometric) and irradiance (allowing meteorological and astronomical aspects to be taken into account) or coefficients as explained above.
