The key drivers for Maximum Power Point Tracking (MPPT) solutions in photovoltaic (PV) power plants are independency from solar panels, fast tracking of irradiance and temperature variations, and efficiency of conversion capacity. In the most available MPPT solutions, some issues such as high implementation burden and performance degradation during abrupt changes have not been sufficiently investigated...
Differential power processing (DPP) is a promising architecture to solve an issue caused by mismatch among PV modules. PV to non-isolated port bus (or PV to the virtual bus) is one of the topologies studied in DPP architecture that allows each DPP converters can achieve maximum power point tracking (MPPT) independently. The string current value does not have an effect on MPPT but relates to the power...
The use of solar energy is increasing for power generation and other uses. In order to meet these demands and make better predictions, it is necessary to understand and explain the dynamics of the solar parameters. Nonlinear dynamics and associated tools can provide better results in the analysis. The meteorological events are based time series and has a dynamic chacteristic therefore this paper proposes...
This paper shows the design of a solar tree PV system for charging mobile devices on open urban areas. The solar unit tree was designed according to the environmental conditions of Medellin. Based on the electric consumption calculations of mobile devices, a 3.5 m height-tree was built. It has four leaves made of acrylic with solar panels on the top (SOW sized 54 × 83.2 cm). It illuminates with cold...
In this work we used time series modelling for generating synthetic sets of hourly solar irradiance for the city of Petrolina located in the northeastern region of Brazil. The models were obtained for each month and were based on 20 years of satellite data. For each month, four time series structures were investigated: auto regressive, auto regressive integrated, auto regressive moving average and...
