In this work an application of a novel strategy for the operation of combined heat and power (CHP) systems is analysed considering the results of an optimization analysis performed by means of a home-made code written in Matlab, and the ones relative to dynamic simulations carried out using the commercial software TRNSYS 17. Such approach is mainly devoted to CHP systems operating without load modulation, and it is similar to the classical heat- driven operational strategy, except for the possibility to dump part of the heat produced by cogenerators. The differences between the present approach and the heat-driven strategy without heat dumping are shown for a case study represented by a residential micro-CHP system, composed of a prime mover, a thermal energy storage system and an auxiliary boiler, producing electricity and heat for a single-family house located in Italy. In particular, it is shown that heat dumping can involve a considerable reduction of the heat storage system size, with a negligible decrease of the useful energy produced by the micro-CHP system.

Abstract
In this work an application of a novel strategy for the operation of combined heat and power (CHP) systems is analysed considering the results of an optimization analysis performed by means of a home-made code written in Matlab, and the ones relative to dynamic simulations carried out using the commercial software TRNSYS 17. Such approach is mainly devoted to CHP systems operating without load modulation, and it is similar to the classical heat- driven operational strategy, except for the possibility to dump part of the heat produced by cogenerators. The differences between the present approach and the heat-driven strategy without heat dumping are shown for a case study represented by a residential micro-CHP system, composed of a prime mover, a thermal energy storage system and an auxiliary boiler, producing electricity and heat for a single-family house located in Italy. In particular, it is shown that heat dumping can involve a considerable reduction of the heat storage system size, with a negligible decrease of the useful energy produced by the micro-CHP system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
