Abstract: VLS-PV systems in desert area are promising in view of rich irradiation and huge land area. But its desert situation, transmission loss may be barrier to realize. This paper is described about estimation of transmission loss without detail irradiation data.
The performance of a photovoltaic (PV) system is highly affected by different types of power losses which are incurred by electrical equipment or altering weather conditions. In this context, an accurate analysis of power losses for a PV system is of significant importance.
Increasing the absorption angle is a commonly used method to suppress this loss process. Non-radiative recombination loss and series loss are extremely significant for the high-concentration-ratio photovoltaic system, covering 15%–40% of the total incident solar energy for the cells with bandgap below 2.0 eV in the case of 100 suns.
Performance metrics such as performance ratio and efficiency have been widely used in the literature to present the effects of the total power losses in PV systems.
One solution is to integrate clean and renewable energy sources to the power system. However high penetration of renewable energy sources can affect transmission line thermal limits and harmonics injection in the system. This paper illustrates the optimal location of Photovoltaic (PV) plant penetration in power system.
Considering that the parameters of the cells greatly affect the loss processes in photovoltaic devices, the sensitivities of loss processes to structure parameters (e.g., external radiative efficiency, solid angle of absorption, resistances, etc.) and operating parameters (e.g., operating temperature) are studied.
As for the voltage losses, the components due to Carnot loss, angle mismatch loss and NRR loss are all enlarged for they are proportional to the temperature of the cell, and the component due to series resistance varies with output photocurrent density, for it is proportional to J2MPP-f.
