Demonstrating the benefits of thermoelectric‐coupled solar PV system in microgrid challenging conventional integration issues of renewable resources
摘要： Incorporation of solar photovoltaic (SPV) and thermoelectric (TE), termed as solar photovoltaic‐thermoelectric (SPV‐TE) hybrid system, is found be a very promising technique in widening the utilization of solar spectrum and improving the power yield viably cum‐proficiently. This hybrid architecture caters thermal energy, which signifies upon electrical energy with additional harnessing of solar insolation in an exceptional way. The implementation of the aforementioned system in microgrid (MG) leads to procurement of higher active power and comparably lesser reactive power to the system. Many non-conventional energy sources have been implemented for power generation in MG in spite of their instability and reconciliation issues. This article portrays upon the main concern of implementing only SPV‐TE system in MG by considering two systems to analyze and compare. Those two systems, ie, SPV‐wind energy system (SPV‐WES)/fuel cell technology (FCT) and SPV‐thermoelectric generator (SPV‐TEG)‐WES/FCT, were analyzed and validated over the employment of only the SPV‐TEG system. For WES and FCT, the proposed system delivers higher active power near about 20% to 70% over the conventional MG and the TEG‐integrated MG; 21% to 52% lesser reactive power is absorbed over the conventional MG and 7% to 17% higher reactive power is absorbed over the TEG‐integrated MG. This, thus, brings about the lesser multifaceted nature in source incorporation and moderating the cons of coordinating WES and FCT, considering all its application. The proposed replaceable SPV‐TEG framework in MG is observed to exceed expectations over the two frameworks offering ascend to a noteworthy leap forward in advancement of SPV. The whole system was studied, analyzed, and validated in MATLAB/Simulink environment.

Employment of solar photovoltaic‐thermoelectric generator‐based hybrid system for efficient operation of hybrid nonconventional distribution generator
摘要： Solar photovoltaic system (SPV) has gained tremendous popularity among researchers as well as in industrialists. Although SPV is a transparent way of electricity generation; still, it suffers from lower quantum efficiency. During the conversion process, solar insolation received by the SPV array turns the system intensely heated at the back side of the modules giving rise to high temperature. This heat is further utilized by the process of thermoelectric effect for electricity generation by thermoelectric generators (TEGs). The combined photoelectric‐thermoelectric effect generates a significant amount of power for the system. This paper portrays on implementation of the aforementioned SPV‐TEG system in hybrid nonconventional distribution generator (h‐NDG) in order to retrieve enough power from SPV array giving rise to higher active power delivery to the system and lower the reactive power absorbance by the system. The comparative analysis is done under two subsystems such as solar PV‐TEG‐wind energy system (WES) over solar PV‐WES and solar PV‐TEG‐fuel cell technology (FCT) over SPV‐FCT. Several constraints like active power, reactive power, and solar power are studied for every subsystem under healthy and faulty conditions. The entire system is modeled, studied, and validated in the MATLAB‐Simulink environment.
