Abstract

International Conference on Advances in Energy Systems and Environmental Engineering (ASEE) -- JUL 02-05, 2017 -- Wroclaw, POLAND

Highlights

The share of solar power generation inside the overall electricity generation is rapidly increasing, thanks to the developments in solar photovoltaic (PV) technology [1]
A critical observation is that the conversion of real averaged solar radiation values into real electrical power exhibits a hysteresis function relation for both the fixed and active tracking PV panels
As a novel contribution, the nonlinear and time-varying relation between solar radiation and power generation is modelled as three-parts hysteresis function, corresponding to the morning, noon, and afternoon time segments

Summary

Introduction

The share of solar power generation inside the overall electricity generation is rapidly increasing, thanks to the developments in solar photovoltaic (PV) technology [1]. We approach the modelling problem through simultaneous observation of solar radiation values, temperatures, solar power output of active sun tracking and fixed PV systems in a controlled environment in Eskisehir. A critical observation is that the conversion of real averaged solar radiation values into real electrical power exhibits a hysteresis function relation for both the fixed and active tracking PV panels. The hysteresis is in the form that the nonlinear relation between a solar radiation value and its corresponding electrical power changes in time This time variance was not reported or modelled in the literature before. As a novel contribution, the nonlinear and time-varying relation between solar radiation and power generation is modelled as three-parts hysteresis function, corresponding to the morning, noon, and afternoon time segments. Efficient system models are expected to be achieved for two widely popular PV panel types
