Long-lived and sustainable energy sources that are able to supply power in an uninterrupted way without need of maintenance for many years are a topic of interest for many researchers. Thermoelectric generators using radioisotope heat source are currently the longest-lived sources of energy that require no refuelling or other maintenance. Such energy system is also safe and clean. In this article, a mathematical model developed for simulation of a radioisotope thermoelectric generator is presented. The model was prepared using MATLAB/SIMULINK software. It allows performing dynamic simulations of radioisotope thermoelectric generator behaviour with varying load conditions as well as in-time simulations to investigate the effect of aging. A brief theoretical introduction to the topic of thermoelectric generators with radioisotope heat source is presented. Other energy sources typically used in space and remote applications such as fuel cells and photovoltaic systems with auxiliary battery storage are also mentioned and briefly compared. Two cases of radioisotope thermoelectric generator behaviours were simulated. In the first case, the effect of radioisotope decay was investigated, while in the second case the simulations were done at various time instances with varying load conditions. Data received from the simulations was organized and presented. The developed model allows investigating the impact of several thermoelectric generator-working parameters and it is easily modifiable, what could allow performing simulations that are more detailed.
