Resumen
The invention can be included in the technical field of the methods for calculating the power generated by electrical centres based on intermittent power sources, wherein said method accurately reproduces the dynamic in the power generated by a set of dispersed photovoltaic systems in all the relevant parameters for the operator of the electrical system (transport and/or distribution), thereby being able to check the robustness of the network in terms of voltage and frequency without the need for monitoring and/or telemetering of the photovoltaic systems, based on only the irradiation incident on a location, the number of photovoltaic systems comprised and the average surface of same.
