In this paper we introduce FYPSim, a system-level framework with application to the design of wireless sensor networks. We illustrate some of the key features of the proposed framework in terms of modeling energy harvesting technologies, evaluating energy storage technologies, and comparing energy prediction algorithms.
This paper presents the design, implementations and verification of Thermoelectric generator (TEG) modules using a first order plus dead time (FOPDT) in Matlab/Simulink™ program. The proposed models were designed to enhance the thermoelectric generator performance in a condition of the inlet fuel control system. The proportional-integral-derivative (PID) controller was tuned with Dahlin synthesis...
Every manufacturing process leaves waste to environment. Some waste must be controlled. Some waste can be utilized. Like the organic fertilizer plant, it leaves waste from chicken manure digestion of bacteria. The air pollution has ammonia gas and heat. The gas has to be deodorized by deodorizer tank. On the other hand, the heat can be harvested for electrical energy. The plant needs to monitor ammonia...
This contribution presents a simulation model of an Energy Harvesting System (EHS) based on Thermoelectric Generators (TEGs) using waste heat from the exhaust pipe of an oil-fired heating system. The overall system is modeled and simulated in the component-oriented environment Modelica®/Dymola®. The model is used to analyze and verify different control concepts to maximize the power output of the...
This paper describes a novel approach to thermoelectric generator modeling as complex energy harvesting system. The thermoelectric generator model includes three main effects that are Thomson effect, Seebeck effect and Joule heat. The influence of heat sources and heat sinks as well as the load resistance that significantly affect properties of thermoelectric generator is also considered. The SimScape...
This paper is an attempt of detail the comparative study of the analysis of thermoelectric module (TEM) for static and dynamic modeling with temperature dependent parametric variations. This study provides an insight on computation of various parameters of TEM used for modeling power generators. Initially a brief analysis is carried out for estimation of efficiency, power, voltage and current assuming...
The high temperature exhaust gases from vehicles are utilized to produce electric power by the MHD (magnetohydrodynamic) energy conversion generator. The electrical energy can then be used to replace existing alternator recharging systems in today's vehicles or in future hybrid-electric vehicles, and both of them to power the vehicle on-board electric energy storage systems. The MHD power generator...
A 3-D finite element model of two-stage thermoelectric generator based on low-temperature thermoelectric material bismuth-telluride and medium-temperature thermoelectric material skutterudites is established. Based on the formal model, structural optimization of the two-stage thermoelectric generator is carried out. Results show that, reasonable design of the structure of two-stage thermoelectric...
