“…In [9], [11] and [12], the standard static mathematics defining various TEG and TEC parameters as well as their modeling are demonstrated. We developed further and present in the following sections: i) TEGs and TECs maths and ii) the implemented models (based on their maths) using Matlab/Simulink and the simulations of TEG/TEC modules, be it in series and or in parallel connections.…”

“…The derivations thus far of the TEG and TEC parameters have been based-on the p-n junction thermoelement resistance at the thermocouple level and by extension at the module level as indicated in [9], [11] and [12]. However, in practice, more than one TEG and TEC modules will be needed for more power production and this will take the form of series and or parallel connections; as a result, the electrical resistance will often change.…”

“…A TEG model was developed in [10] for maximum power point tracking but lacks the detailed underlining maths and the parallel TEG combinations was limited to just 2. A comprehensive TEG and TEC models with the detailed maths supporting the TEG and TEC models, were presented respectively in [11] and [12]. In [13], a modeling of TEG using Modelica is asserted but deficient in the comprehensive maths, especially considering modeling infinite multiple TEGs and as well TECs modules -which were not articulated.…”

Sustainable energy is gradually becoming the norm today due to greenhouse warming effects; as a result, the quests for different renewable energy sources such as photovoltaic cells as well as energy efficient electrical appliances are becoming popular. Therefore, this article explores the alternative energy case for thermoelectricity with focus on the steadystate mathematics, mixed modelings and simulations of multiple TEGs and TECs modules to study their performance dynamics and to establish their optimal operation points using Matlab and Simulink. The research substantiates that the output current from TEGs or input current to TECs, initially respectively increases the output power of TEGs and the cooling power of TECs, until the current reaches a certain maximum optimal point, after which any further increase in the current, decreases the TEGs' and or TECs' respective output and cooling powers as well as efficiencies, due to Ohmic heating and or entropy change caused by the increasing current. The research main contributions are elaborate easy to understand TEGs/TECs theoretical formulations as well as static and dynamic simulated models in Matlab/Simulink, that can be used initially to dynamically investigate an infinite quantity of TEG and TEC modules connections, be it in series and or in parallel. This is to assist system designers grasp TEGs and TECs theoretical operations better and their limits, when designing energy efficient waste heat recovery (using TEGs)/cooling (using TECs) systems for industrial, residential, commercial and vehicular applications.

“…Since the heat energy involves in the proposed system, the modelling of the heat energy part of the TEG array needs to be considered. The heat power generated at the low and high-temperature sides of the TEG array (Ql and Qh, respectively) is calculated using ( 3) and ( 4) [16]. In the model, the thermal conductance, Ktc, are considered.…”

<span lang="EN-US">Energy storage plays an important role in the future of the power system. There are a lot of energy storage system (ESS) available and thermal energy storage shows a promising future. Conventionally, this system is based on a steam generator that converts heat energy to electrical energy and an electrical heater to convert electrical energy to heat energy. Nonetheless, there is still no proper ESS based on the thermoelectric generator (TEG), which can convert directly heat energy to electrical energy and vice versa. This paper proposed a power converter with a new controller for the thermal ESS based on the TEG. The bidirectional converter and the modified perturb and observe method are used to manage the energy transfer at the TEG. The thermal energy storage is based on the sensible approach, where the heat energy causes the temperature to increase. The results show that the thermal ESS based on the TEG is feasible since the energy can be stored and released from the proposed system.</span>
