A thermal model for photovoltaic systems
A. D. Jones,Chris Underwood +1 more
TL;DR: In this article, the energy balance of photovoltaic (PV) cells is modelled based on climate variables, and it is found that the most precise fit to measured data is obtained by fitting the value of the forced convection coefficient for module convection.
Journal ArticleDOI
Building thermal model reduction using nonlinear constrained optimization
TL;DR: In this article, a nonlinear constrained optimization method is used for reducing the model order of building elements, which involves minimizing the error between the step response of a high-order reference model whilst tuning the parameters of a lower order model in order to obtain an optimized reduced-order model.
Book
Modelling Methods for Energy in Buildings
TL;DR: In this paper, the authors provide an understanding of the concepts and principles behind predictive modeling methods; review progress in the development of the modelling software available; and explore modelling in building design through international case studies based on real design problems.
Journal ArticleDOI
Performance analysis of the Chena binary geothermal power plant
TL;DR: In this article, the IPSEpro model of the Chena Geothermal ORC Power Plant had been developed and validated using the real data, and the validated model was used to investigate the effect of variation in the geothermal source temperature on plant performance.
Journal ArticleDOI
Thermal comfort based fuzzy logic controller
TL;DR: In this paper, the predicted mean vote (PMV) is used to control the indoor temperature of a space by setting it at a point where the PMV index becomes zero and the predicted percentage of persons dissatisfied (PPD) achieves a maximum threshold of 5%.
