Distributed multi-generation systems: energy models and analyses

摘要: The recent development of distributed generation technologies is changing the focus production electricity from large centralized power plants to local energy systems scattered over territory. Under paradigm, present research scenario emphasises more and role solutions aimed at improving efficiency thus sustainability overall sector. In particular, coupling cogeneration various typologies chillers heat pumps allows setting up multi-generation for combined different vectors such as electricity, (at enthalpy levels), cooling power, so forth. final demand outputs close users enables reducing losses occurring in chain conversion distribution, well enhancing efficiency.This book presents a comprehensive introduction planning performance assessment within so-called Distributed Multi-Generation (DMG) framework. Typical plant schemes components are illustrated modelled, with special on applications trigeneration power. A general approach characterization formulated terms lambda analysis, which extends classical models related heat-to-power ratio analysis plants. unified theoretical framework leading synthesize techniques described details. indicators presented evaluating potential benefits respect case separate systems. Several study exemplify point out some numerical aspects relevant equipment available market. prime mover typologies, electric, absorption engine-driven pumps, discussed evaluated. number openings towards modelling evaluation environmental economic issues also provided. analysed highlight prominent DMG sustainable scenarios.
