Dear CAST community, I am pleased to announce a special issue for the journal Processes, with the theme Modeling and Simulation of Energy Systems. This special issue will curate novel advances in research which either use modeling and simulation as an important component of the analysis of energy systems, or, present the development of new and better models of energy systems or energy system components. In order to maximize impact, authors contributing to this special issue will be invited to deposit their process models in the open access repository for the process systems engineering community at http://PSEcommunity.org and/or provide as supplementary material. These may include contributions such as process simulation files, computer code, spreadsheets, model files, optimization codes, or other relevant digital objects used for modelling and simulation purposes with either commercial or open source software. Topics include, but are not limited to: * The development of models or simulations of individual process units contained within energy systems * The development of models or simulations of energy process systems * Simulation techniques, software, algorithms, or other tools for modeling and simulation * Design, analysis, control, optimization, operation, planning, or scheduling of an energy system that employs models or simulations, such as techno-economic analyses, energy/exergy analyses, environmental or life cycle analyses, value and supply chains analysis, or other. For those new to the journal, I am happy to provide (upon request) the reviews that I received on my own recently published article in Processes, unfiltered, to give a sense of the rigor of the review process. Processes is an open access journal. Article publishing charges are only 350 CHF (about $375 USD) if the manuscript is submitted by July 1, and 850 CHF after. The final date for submission is September 15, 2018.
