Thermo-economic driven planning of resource-efficient district combined cooling and power

Abstract

Accordingly, an optimization tool has been modeled to find optimal planning, sizing and scheduling of trigeneration systems. The tool is used in decision-making process in all project phases. This is done by applying the energy hub concept under the constraints of maximizing a formulated combined efficiency that contains (aAnnualized total cost saving ratio (ATCSR),, exergy efficiency (EXEff),, fuel saving ratio (FSR) and carbon dioxide reduction ratio (CO2RR) using a weighing factor method. This is made by comparing each indicator them to a conventional system in GAMS. Moreover, economical parameters (net present value, internal rate of return and payback period) are used to guarantee proper decision-making process. Using part load effect and variable capital costs of components to simulate the real case, the tool provides optimal planning, sizing and scheduling of all trigeneration systems.
