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.

定义在常规和热电耦合微电网中提高可再生能源渗透率的不可缺少的存储：建模，分析和验证

清洁，高效，可持续，有效，安全和可靠的电力需求的膨胀已经以微妙和加快的速度引发了微电网（MG）的极大兴趣。提高可靠性的必要性，燃料的多样性，温室气体的减少，严重的天气波动等，都刺激了MG概念不仅在公用事业级别而且在客户和社区级别都得到了应用。发现将太阳能光伏（SPV）和热电（TE）结合使用被称为太阳能光伏-热电（SPV-TE）混合系统是一种非常有前途的技术，可以扩大太阳光谱的利用并有效地提高功率输出。这种混合体系结构可通过额外的热能来满足电能需求，这意味着以一种特殊的方式利用了日照。但是，为了将电压曲线保持在允许的水平，MG需要使用存储机制来平滑可再生功率不稳定性，显着满足高有功功率并避免长期无功功率上升。本文说明了三种系统的比较分析，例如常规MG； TE耦合的常规MG，以及仅基于TE耦合的基于太阳能PV的MG，定义了必须使用储能系统（ESS）。概述了第三种系统的优越性，其原因在于其源集成的复杂性降低，减轻了现实生活中风能系统（WES）和燃料电池系统（FCT）集成的危害，提供了更高的有功功率以及更少的无功功率吸收其他两个系统。
