Electrical power consumption in Peru increased on average by 5.1% between 2002 and 2011, while demand increased from 2 700 MW to 4 800 MW as a consequence of the increase in GDP. On the other side, photovoltaic (PV) technologies have been used in Peru for power generation in a few thousand small solar home systems (SHS) in the last 25 years, through various rural home electrification programs. This has permitted to accumulate a large amount of experience, which would open the possibility to consider the installation of larger PV systems with connection to the grid. Likewise, in the last five years, power generating plants have been installed to inject power directly in the National Power Grid (SEIN, from its Spanish acronym) without any substantial intervention of the national engineering community. One can see that in this scenario of technological evolution, PV technologies is present ...

El consumo de la energía eléctrica en el Perú se incrementó 5,1% en promedio entre los años 2002 y 2011 mientras que la demanda creció desde 2 700MW hasta 4 800MW como consecuencia del incremento del PBI. Por otro lado, el Perú ha aplicado la tecnología FV para generar electricidad instalando algunos miles de pequeños sistemas fotovoltaicos (SFD) en los últimos 25 años en programas de electrificación rural domiciliaria que le ha permitido acumular notable experiencia que lo sitúa en condiciones expectantes para abordar la posibilidad de hacer instalaciones de mayor potencia FV con conexión a la red pública. Así mismo, en los últimos 5 años se han instalado plantas de generación de EE que la inyectan directamente a la red del SEIN sin intervención sustantiva de la ingeniería nacional, este escenario de avance tecnológico FV cubre los extremos de una escala de generac...

The characterization of the nominal power under real operating conditions is crucial for the correct evaluation of a photovoltaic generator. Several earlier studies proposed different methods based on empirical models for the estimation of the nominal power. These methods require experimental data obtained during optimal days under clear sky conditions and are not suitable for days deviating from these optimal conditions and, thus, generating a significant amount of noise in the data. In this sense, we propose a non-parametric statistical approach to filter out this noise to reliably estimate the real nominal power in the latter conditions. The period of study was 107 days. These were divided in two categories, clear and partly cloudy sky conditions. The results show that our statistical method allows to obtain the same nominal power under partly cloudy conditions as under clear sky. Thi...
