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.
