The inflation of clean, efficient, sustainable, effective, secure, and reliable electricity demand have been triggered much interest for Microgrid (MG) at a miraculous and quickened pace. The necessity of reliability enhancement, diversity of fuel, cutback of greenhouse gases, severe weather fluctuation etc. has stimulated the inclusion of MG concept not only in utility level but also in customer and community level. Incorporation of solar photovoltaic (SPV) and thermoelectric (TE), termed as Solar photovoltaic-thermoelectric (SPV-TE) hybrid system is found be a very promising technique to broadening the utilization of solar spectrum and enhancing the power output effectively-cum-efficiently. This hybrid architecture caters electrical energy with additional thermal energy that signifies upon harnessing of solar insolation in an exceptional way. But in order to retain the voltage profile in the permissible level, MG needs storage mechanism for smoothening of renewable based power inconstancy, catering high active power significantly and dodging the long term reactive power rising. This paper illustrates the comparative analysis of three systems such as Conventional MG;TE coupled Conventional MG, and only TE coupled solar PV based MG defining the necessity of employment of energy storage system (ESS). The superiority of third system has been outlined in terms of lesser complexity in source integration, mitigating the detriment of Wind energy system (WES) and Fuel Cell Systems (FCT) integration in real life application, delivery of higher active power, and lesser reactive power absorbance over the two other systems. The studied system is modeled in MATLAB/Simulink environment and the results are presented to support, verify, and validate the analysis. K E Y W O R D S active power,

Summary Utilization of a broad range of solar spectrum has the potential for high power output from solar cells. However, solar photovoltaics (PVs) can convert only part of the solar electromagnetic spectrum into electricity efficiently. The remaining of the solar radiation is often dissipated in the form of heat, which causes performance reduction and reduces the life expectancy of the solar PV cell. Thermoelectric generators (TEGs) are devices that operate like a heat engine by converting thermal energy into electricity through thermoelectric effect. Integrating a TEG into a PV converter will enhance its efficiency and reduce the amount of heat dissipated. Different studies have been carried out and are still taking place to increase the total efficiency of a coupled photovoltaic thermoelectric generator (PV‐TEG) system. This review discusses the concept of PV converters and thermoelectric devices and presents the various models and numerical and experimental investigations on performance enhancement of integrated PV‐TEGs. The influence of key parameters on the performance of PV‐TEG were also discussed. The review is expected to serve as a reference to recent work on research and development of integrated PV‐TEG systems.

Summary The photovoltaic‐thermoelectric hybrid system (PVTE) is less sensitive to the photon wavelength than the pure PV system. This phenomenon can make the PVTE to be a good method of obtaining electrical energy from solar energy. A challenge of this system is how to distribute the energy in the working process. To solve this problem, this paper establishes a thermodynamic model to study the energy matching mechanism of the hybrid system. The influence of dynamic solar radiation has been considered in the model. The result indicates that the relationship between the PVTE efficiency and the PV bandgap looks like a “reverse U" (rises first and falls later). The impacts of the optical concentration ratio and the TE parameters on the optimal PV bandgap are studied. No matter how these two parameters change, the optimal PV bandgap of the PVTE is around 1.15 eV. It illustrates that the energy match does not depend on the solar radiation and the TE parameters. The effect of the phase change material has also been considered. The melting temperature, mass and heat capacity of the phase change material have been considered in the numerical model. The melting temperature is proved to be important for determining whether it needs to use the phase change material and how much heat should be stored.
