The objective is to minimise the net present cost. An advanced battery model and the accurate calculation of the net present cost (including all the costs during the system lifetime) are considered in the optimisation of this kind of systems. The standard simpli ed model of the thermoelectric generator is used, as more complex models cannot be used in an optimisation framework, where hundreds or thousands of di erent cases must be simulated (each combination of components must be simulated at least during one year, in 1-min steps). The optimization is carried out e ciently by means of genetic algorithms. The method has been applied in the optimisation of two cases of low consumption o -grid households (Cambodia and Norway). Thermoelectric generator (costing €8/W) is part of the optimal solution in the case of Norway. In Cambodia, to be part of the optimal system, acquisition cost of the thermoelectric generator should be reduced by 25%. info:eu-repo/grantAgreement/ES/MEC/PRX18-00030 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 8.208 2019 ENERGY & FUELS 11 / 112 = 0.098 2019 Q1 T1 THERMODYNAMICS 2 / 61 = 0.033 2019 Q1 T1 MECHANICS 3 / 136 = 0.022 2019 Q1 T1 2.924 2019 Energy Engineering and Power Technology 2019 Q1 Renewable Energy, Sustainability and the Environment 2019 Q1 Nuclear Energy and Engineering 2019 Q1 Fuel Technology 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Champier, Daniel Gibout, Stephan Lujano-Rojas, Juan M.
