Techno-Economic Analysis of Alternative PV Orientations in Poland by Rescaling Real PV Profiles

Abstract

This paper presents factors affecting the effectiveness of photovoltaic (PV) plants and issues occurring in the distribution system network due to the high penetration of conventionally designed PV plants. Factors analyzed in this paper are shading, distance between panels, location of PV plants, European grid code requirements, and network constraints. Their impacts on the effectiveness of the PV power plant are presented one by one. Furthermore, the 1-year power profile of a real PV plant is rescaled to different orientations, and the energy effectiveness of different variants is compared. Finally, the economic aspects are considered by multiplying the energy produced by the energy prices. At the end, final conclusions are given and further research is outlined.

Progress and Challenges Connected with the Integration of Renewable Energy Sources with Railway Distribution Networks

“…In order to maximize the connection capacity, one should adapt the generation profile to the load profile. Adaptation can be achieved by adapting the power of PV panels as well as the orientation of PV panels or by careful analysis of the wind profile [67]. Despite the energy balance, one need to consider dynamic issues, among which the most basic issue is a high variability in the load, which results in rapid voltage drops and flicker factor degradation.…”
