“…An MPP tracker should constantly ensure that a PV module is at its MPP; this is realized by power electronic circuits, in which pulse-width modulation techniques are employed with a feedback loop to sense PV output power upon changing the voltage over the module or system until maximum power is reached [14,15]. Here also DC-DC converters (buck-boost, boost-buck) are used: low-power inverters use metal-oxide-semiconductor field-effect transistor (MOSFET) thyristors in high-power applications, and typical efficiencies are 98% [15]. DC-AC conversion can be achieved on the basis of square wave, sine or modified sine wave, or pulse-width modulated inverters [15].…”

“…Operation temperature and the rate of charge and discharge affect the performance and lifetime of a battery. The overall efficiency of charging and discharging is about 90% [15]. Usually slow discharge rates lead to longer lifetimes, while at low temperatures, discharge rates can decrease considerably.…”

Resumo-O fenômeno do ilhamento ocorre quando um Sistema de Geração distribuída permanece energizado após a interrupção da rede da concessionária. A ocorrência de ilhamento não intencional pode acarretar em diversos problemas relacionados à segurança dos usuários e operadores do sistema elétrico e perda da qualidade de energia elétrica. Nesse contexto, o presente trabalho apresenta um novo método ativo de Proteção Anti-Ilhamento (PAI) com realimentação positiva de frequência. Para atestar a efetividade da estratégia, será realizado um estudo comparativo entre o algoritmo proposto e outras técnicas conhecidas na literatura: Active Frequency Drift (AFD), Sandia Frequency Shift (SFS) e uma variante do AFD proposta em 2013. Os ensaios experimentais serão realizados empregando um inversor CC-CA de 1 kW, a rede da concessionária e uma carga RLC, projetada segundo as recomendações da norma ABNT NBR 62116. Os resultados obtidos comprovarão que a técnica proposta apresenta uma redução da Zona de Não de Detecção, do tempo de detecção do ilhamento e do conteúdo harmônico inserido na corrente de saída do inversor.

“…Globally, there is a growing utilisation of PV modules for electricity generation compared to other renewable energy technologies [133]. The design and material parameters of a PV module influence the power characteristics of the array [134]. Although both mono-crystalline and polycrystalline PV modules [18] are currently in use, the prospects of perovskite solar cells appear to be changing the landscape of PV power generation [135,136].…”

Integrated photovoltaic-fuel cell (IPVFC) systems, amongst other integrated energy generation methodologies are renewable and clean energy technologies that have received diverse research and development attentions over the last few decades due to their potential applications in a hydrogen economy. This article systematically updates the state-of-the-art of IPVFC systems and provides critical insights into the research and development gaps needed to be filled/addressed to advance these systems towards full commercialisation. The design methodologies, renewable energy-based microgrid and off-grid applications, energy management strategies, optimisations and the prospects as self-sustaining power source were covered. IPVFC systems could play an important role in the upcoming hydrogen economy since they depend on solar hydrogen which has almost zero emissions during operation. Highlighted herein are the progresses as well as the technical challenges requiring research efforts to solve to realise numerous potential applications of IPVFC systems such as in unmanned aerial vehicles, hybrid electric vehicles, agricultural applications, telecommunications, desalination, synthesis of ammonia, boats, buildings, and distributed microgrid applications.
