Mismatch losses in PV power plants

Solar Energy, 2014
Abstract In this paper, two different PV arrays have been simulated in order to quantify the electrical mismatch loss in each one of them. The simulations have been performed both in the standard condition (STC) and in the dynamic conditions which implement the meteorological data from the two different locations.

Forecasting photovoltaic array power production subject to mismatch losses

Solar Energy, 2010
The development of photovoltaic (PV) energy throughout the world this last decade has brought to light the presence of module mismatch losses in most PV applications. Such power losses, mainly occasioned by partial shading of arrays and differences in PV modules, can be reduced by changing module interconnections of a solar array. This paper presents a

Analysis Model of Mismatch Power Losses in PV Systems

Journal of Solar Energy Engineering, 2009
A novel procedure to extract and analyze the power losses, mainly due to mismatch effects, in a photovoltaic (PV) system is presented. The developed model allows the extraction of the main PV module and PV array parameters from I-V characteristics, as well as in dynamic behavior under real conditions of work.

Module mismatch loss and recoverable power in unshaded PV installations

2012 38th IEEE Photovoltaic Specialists Conference, 2012
Distributed electronics which optimize power in PV systems have the potential to improve energy production even under unshaded conditions. This work investigates the extent to which mismatch in the unshaded electrical characteristics of PV panels causes system-level power losses, which can be recovered in arrays employing power optimizers.

Analysis and control of mismatch power loss in photovoltaic arrays

Progress in Photovoltaics: Research and Applications, 1995
AbstractConnecting photovoltaic cells to form an array can cause problems when the characteristics of the cells are not matched. This problem, known as mismatch, can reduce the power output of the array and lead to cell degradation through localized heating of individual cells. Such problems can arise simply through the shading of a single cell.

Mismatch Power Loss Reduction on Thermoelectric Generator Systems Using Maximum Power Point Trackers

2006 25th International Conference on Thermoelectrics, 2006
A new concept of maximum power point tracking control method for Thermoelectric Power Generator (TEG) systems has been developed. The virtual load conductance of the load is feedback controlled to maintain the same value of the internal conductance of the Thermoelectric (TE) array using DC-DC converter.

Mismatch losses in PV power generators caused by partial shading due to clouds

2013 4th IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2013
Clouds cause spatial and temporal variability of solar radiation which is the main cause of fluctuating photovoltaic power fed into the grid. TUT solar PV power station research plant has been designed to enable systematic and thorough analysis of the dynamic phenomena in energy conversion processes of grid-connected solar PV power systems.

Predicting Power Loss Due to Module Mismatch in Utility-Scale Photovoltaic Systems

2017 IEEE 44th Photovoltaic Specialist Conference (PVSC), 2017
A model is proposed for simulating power loss in utility-scale photovoltaic (PV) systems due to mismatch of module electrical characteristics. The main input to the model is a set of current-voltage (I- V) curves of thin-film Cadmium Telluride (CdTe) modules.

Interconnection Topologies for Floating Photovoltaic System to Enhance the Power Output by Reducing the Mismatch Losses

2022 IEEE PES 14th Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2022
Floating photovoltaic (FPV) systems are the global trend in solar power generation technology with the added advantage of reducing the water crisis in this climate change. The automatic cooling effect maintaining the panel temperature increase the energy output from these water-based PV systems compared to land-based systems.
