The Importance Of Derivatives For Simultaneous Optimization Of Sizing And Operation Strategies: Application To Buildings And Hvac Systems

Van-Binh Dinh, Benoit Delinchant, Frederic Wurtz

Abstract: This paper presents optimization approaches for a complex nonlinear constrained optimization problem: sizing integrating operation strategies of energy systems (heating, ventilation) for positive energy buildings. This is a multi-criteria optimization problem of big size with differentiable objective functions (thermal comfort and life-cycle cost) and a lot of continuous decision variables. To solve it, 2 optimization methods will be studied: (i) derivativefree method (NSGA2) et (ii) derivative-based method (Sequential Quadratic Programing). The study case is a positive energy house in South-East of France in which we will show that derivative-based optimization approach will be more efficient with much less computation time and a better quality of Pareto front solutions.
