Modeling Renewable Energy Systems in Rural Areas with Flexible Operating Units

Designing energy systems becomes more and more important as distributed and renewable energy production gains attention. As distributed systems have quite different challenges than centralized ones, novel solution methods are in demand and have been proposed. Sustainability is an ever increasingly i...
