A Co-Powered Biomass and Concentrated Solar Power Rankine Cycle Concept for Small Size Combined Heat and Power Generation

Abstract

Abstract:The present work investigates the matching of an advanced small scale Combined Heat and Power (CHP) Rankine cycle plant with end-user thermal and electric load. The power plant consists of a concentrated solar power field co-powered by a biomass furnace to produce steam in a Rankine cycle, with a CHP configuration. A hotel was selected as the end user due to its high thermal to electric consumption ratio. The power plant design and its operation were modelled and investigated by adopting transient simulations with an hourly distribution. The study of the load matching of the proposed renewable power technology and the final user has been carried out by comparing two different load tracking scenarios, i.e., the thermal and the electric demands. As a result, the power output follows fairly well the given load curves, supplying, on a selected winter day, about 50 GJ/d of thermal energy and the 6 GJ/d of electric energy, with reduced energy dumps when matching the load.

A review of solar energy based heat and power generation systems

“…This interest comes from many reasons such as utilizing a local energy source which is freely available, reducing the dependency on fossil fuels, or even reducing the consumption of biomass through hybridization [101]. Most of the research has been conducted for residential scale consumers, but several other plant scales have also been analysed such as schools [39], hospitals [53], multi-unit dwellings [74], industrial processes [73,104,121], hotels [100,123], district energy supply [92][93][94]101], and specific end-uses such as swimming pool heating [49]. Since evaluating the possibilities for fully renewable solar energy based CHP plants is a recent field of research, the main focus until now has been on evaluating suitable plant configurations for different locations around the world.…”

Energy efficiency and renewable energy integration in data centres. Strategies and modelling review

“…Research in RES and its implementation to different applications has been under interest for many researchers worldwide. As examples of renewable energy integration in real systems, one can find in the available literature from technical and financial analysis viability of grid-only, RES-only and grid/RES hybrid power supply configurations for a large-scale grid-connected hotel [69] to the combination of wind and PV power systems [70], through Combined Heat and Power (CHP) Rankine cycle [71] and solar cooling [72].…”

Performance Evaluation of a Small Scale Modular Solar Trigeneration System

“…They declared that the systems could utilize about 75% of solar energy to provide electric and thermal energy directly to end-users, and the microsystems had relatively the same efficiencies compared to large scale systems which were said to be matured technologies [15]. Borello et al investigated the matching of an advanced small scale combined heat and power (CHP) Rankine cycle plant with end-user (i.e., a hotel) thermal and electric load [16].…”
