This paper focuses on analyzing the behavior of a photovoltaic system installed on a selected building, using the PVcase software to evaluate the influence of temperature on energy performance. The study simulates a typical summer day, comparing the operation of photovoltaic panels during two distinct periods: in the morning, when the ambient temperature is lower, and at midday, when the temperature reaches its peak. Through these simulations, variations in voltage, current, and generated power are determined, as ...

The maritime industry represents a significant contributor to global greenhouse gas emissions, primarily through the combustion of fossil fuels used by ship engines. As international regulations tighten and environmental awareness grows, reducing global greenhouse gas emissions from ships has become an important objective. This study explores the potential for emission reduction on passenger ships through the implementation of a hybrid propulsion system. The study methodology involves solving the following aspects...

In this paper, we present some practical considerations regarding the design of power voltage stabilizer equipment. Nowadays, technologies for raising and/or lowering the voltage to a level required by the power line or a consumer are increasingly used (in wind or solar power generation systems, or in energy conversion systems with a direct current intermediate circuit). Our study refers to a conversion solution consisting of two converter stages. The first stage consists of two boost converters operating in antip...
