Dynamic Operation Optimization of a Trigeneration System

摘要: It is considered that the electric, thermal and cooling loads of a building complex are covered by tri-generation system consisting gas engine with heat recovery, an absorption chiller driven energy, electrically compression chillers two storage tanks (one hot one cold water). Supplementary electricity supplied local network. The behavior such during transients characterized primarily transient performance (start-up shut-down). objective work reported here operation optimization under load-varying conditions taking into consideration three aforementioned components. simulation dynamic chiller, in particular, based on Gompertz function (sigmoid curve). Minimization total cost for covering energy needs selected as function, while operating point each component to be determined specified constraints. optimal values control variables using multi–stage vector parameterization method software Sequential Quadratic Programming. solution problem accompanied sensitivity analysis. Suggestions written continuation improvement work.
