The optimal selection of on-site CHP systems through integrated sizing and operational strategy

• Advanced modelling of the on-site energy generation components (CHP-Boiler).
• Development of integrated CHP sizing and operational strategy selection methodology.
• Evaluation of economical aspect, primary resource consumption and environmental impact.

Achievable outcomes of the combined heat and power (CHP) system applications are subject to several factors. In this study the value of integrated system sizing and operational strategy selection has been evaluated. This would facilitate maximum return on investment as well as reducing primary energy resource consumption and environmental impact. The required model improvements are identified and applied, which will encompass the transient characteristics of the CHP system components and their true operational constraints in a more realistic manner. In addition, the proposed methodology is generic enough to cover energy demand fluctuations of any existing manufacturing plant by aggregated data integration to guarantee improved on-site energy generation system outcomes. Finally the proposed methodology is applied to a pharmaceutical manufacturing plant. The results illustrate promising potential improvements in comparison with existing approaches for CHP system configurations.
