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 ...

This paper presents the modeling and simulation of an electrical energy management system that integrates a 300 V, 8 Ah lithium-ion battery, a DC shunt machine, and a variable DC load using NEPLAN simulation software. The main purpose of this work is to investigate the performance and control behavior of a hybrid electrical system where the power flow is automatically regulated according to the State of Charge (SOC) of the battery. The DC machine alternates between motor and generator modes depending on the SOC le...
