Syllabus
Basic system modelling concepts: state variables, energy and mass balances, simulation parameters and equations, degree of freedom analysis, different types of specifications, inequalities, objective functions.
Energy systems models: steps in model development, steady state and dynamic, lumped and distributed parameter models, flowsheets, degrees of freedom, sequential or simultaneous solving approach, Qualitative techniques - curve-fitting, regression analysis, numerical methods and their implications.
Calculating systems performances: operating cost, efficiency, environmental impact, investments, thermo-economic performances.
Stating and solving optimization problems: decision variables, objective functions and constraints, solving strategies, Unconstrained problems- necessary and sufficiency conditions, Constrained optimisation- Lagrange multipliers, constrained variations, Kuhn-Tucker conditions Linear Programming, pivoting, sensitivity analysis Search Techniques- Univariate/Multivariate. Case studies of optimisation in Energy systems problems.
Course Objectives
