Power improvement in PV panel under temperature variation fault using refrigeration mechanism and its implementation

摘要

Modeling of photovoltaic (PV) panel is the most important part of investigating the effect of fault due to temperature variation. The main objective of this paper is to analyse the effect of fault due to temperature variation and its correction in PSCAD, and real-time implementation using PV panel refrigeration (i.e. cooling) mechanism. Two PV panels are considered for this study among two panels, one panel is considered without cooling and another one is considered with cooling. Using water as a coolant we tried to reduce the temperature of the panel. We have used jute bag soaked with water to cool the panel from back side covering the maximum surface area. Study of the temperature variation effect on PV panel considering with and without cooling is discussed with five different sets of data’s at different irradiation and different temperature.? The effect of fault due to temperature variation on PV panel the power–voltage (P–V) curve, open circuit voltage profile, maximum power and percentage of power profile improvement in PV panel with and without refrigeration mechanism are also studied in this paper. The improvement in power by both simulation and experimental study are observed with the cooling arrangement is connected to the panel compared to without cooling. The experimental setup is installed on the rooftop of G plus 6 block of National Institute of Technology Agartala for the validation of the proposed scheme.
