6. 2 PV in Infrastructure, on Water and on Vehicles; PV and Agriculture
Summary / Abstract:
We introduce a flexible simulation method for analysing and forecasting the energy yield of Vehicle Integrated Photovoltaic(VIPV) systems during trips. The proposed method supports the analysis of the energy performance of moving vehicles without the need of highly specialized monitoring data, but instead weather data retrieved from satellites for locations along the path of motion, are used as an input to the simulation environment. The method provides the freedom to simulate any route during any time of the day, which would enable the analysis of large scale VIPV applications in different vehicle market segments including passenger cars and commercial vehicles. Furthermore, the simulation flow scheme will be flexible enough to incorporate the modelling of PV modules with different sizes, shapes, PV technologies and hence, different nominal power, under various irradiance levels including temperature effects. In this work, we focus on simulating the motion of vehicles and retrieving weather data along the path of motion. We apply a simulation timestep of 1 second which can be either increased or decreased based on desired accuracy and computation power available. Weather data allocation technique along the route is also presented. The orientation of the vehicle along the path is considered in our model by calculation, as it is an important aspect of determining the amount of irradiance reaching all vehicle surfaces. Finally, we demonstrate our approach on an example route and retrieve all the necessary input data needed for the VIPV simulation.
