Embodiment Construction

[0032] figure 1 A photovoltaic device according to one embodiment of the invention is schematically represented. The device comprises a plurality of photovoltaic modules 1 connected to a conventional grid 3 via an inverter 2 . Of course, the modules can also be connected to stand-alone applications via inverters. The device also comprises a control or management unit 10 dependent on a computer comprising software implementing the method of predicting power production as will be described below. The control unit 10 receives measurements of the real power production from the photovoltaic devices 1 , 2 via the link 4 . Furthermore, the control unit 10 receives as input the weather forecast data established by the weather forecast entity 5 via the communication means 6 .

[0033] The control unit 10 thus implements a method of predicting the power production of the photovoltaic device, which method relies on figure 2 The different blocks represented in . The control unit may...

Abstract

A method of forecasting the electrical production of a photovoltaic device comprising photovoltaic modules (1), comprising a first part of estimating the lighting that will be received in the plane of the photovoltaic modules (1) and a second part of estimating the electrical production of the photovoltaic device, characterized in that it comprises the following first step: (E1)-determination of whether a period concerned is sunny or cloudy, and characterized in that it comprises the following second step (E2) of implementing at least one of the following two steps: (E2)-correction of the second part of the method of forecasting the electrical production based on the measurement of the true electrical production of the photovoltaic modules if the period concerned is sunny; and / or correction of the first part of the method of forecasting the electrical production based on the measurement of the true electrical production of the photovoltaic modules if the period concerned is cloudy.

Description

technical field [0001] The present invention relates to a method of predicting the electrical production of photovoltaic devices. It also relates to software implementing the method and photovoltaic devices implementing the method. Finally, it concerns the use of this method for the diagnosis of photovoltaic devices. Background technique [0002] The share of electricity production originating from photovoltaic installations is increasing rapidly. A special feature of this solar production stems from the fact that it is very irregular, since it varies strongly according to meteorological conditions. Now, when these devices are connected to the grid, this unpredictability causes difficulties in managing the entire grid, as it becomes difficult to ensure a balance between energy production and demand. More generally, this unpredictability of electricity production is detrimental to any device that relies at least in part on solar energy for its energy source. [0003] To o...
