Optimal Model of Distributed Energy System by Using GAMS and CaseStudy

PDF Version Also Available for Download.

Description

This paper adopts optimal model which used GAMS to developmethods and tools for conducting an integrated assessment of DER system.Three cases were studied. Energy-saving, environmental and economicefficiency were evaluated. The results of the simulation can besummarized as follows: 1) For the current system, optimal operating timeis about 4,132 hours per year, and from 8 am to 22 pm everyday. 2) It iseconomical when electricity price increases or gas price decreases. 3)According to the load function of system, energy-saving, environmentaland economic efficiency will have amaximum value at optimal operatingtime. 4) Compared with exhaust heat efficiency, power generationefficiency has more influence to ... continued below
