Contribution to the characterization and modeling of photovoltaic generators

Abstract

This Doctoral Thesis contributed to develop a new procedure to calculate the nominal power of a photovoltaic generator, P_(M )^*. Under outdoor conditions, the International Electrotechnical Commission and others have proposed procedures for determining the P_(M )^*of a generator. Following these procedures, it is mandatory to monitor days with ideal conditions, particularly days with clear skies and high irradiance. This thesis proposes a new approach that allows estimating the P_(M )^*with non-ideal even partially cloudy days. This procedure increases the number of adequate monitoring days. To test this, a 109.44 kW plant was evaluated in Granada, Spain and then two smaller generators and in two different cities in Peru: Chachapoyas (tropical highlands) and Lima (coastal desert). The developed procedure can be applied to facilitate technical diligence and quality control processes for generators of different sizes and in different operating conditions.
