Exam 2 Coverage 1.Resource planning models: Be aware of the differences in modeling between the various GEP problems (GEP1-GEP11). I may test your understanding of the significance of these differences, e.g., reserve constraint, capacity credit, accounting for different demands, capacity factor, multi-area representation, representing transmission (with and without limits), inclusion of adequacy constraints, multi-period formulation and end effects, fixed & variable O&M. 2.Decomposition methods: a.Relationship of constraint matrix structure to decomposability; b.Motivation for decomposition methods and relation of solution speed to the number of constraints c.Benders decomposition: Separating a problem into master and primal subproblem Duality in linear programming; relation of strong duality property to use of dual in the Benders formulation; relation of various types of primal solutions to various types of dual solutions. Benders algorithm and Benders optimal rule Be able to work the Benders example given in the notes, pp18-35 Benders simplifications (no optimality test, no feasibility test) 3.Benders as it is applied to EGEAS 4.Benders applied to stochastic programming

Exam 1 Coverage You may work these two problems entirely at home and bring them to the exam. You should NOT collaborate with anyone in working these problems. But you can use any resource you like, e.g., notes or books. 1.This question is to be worked before Exam 2 but turned in with Exam 2. Consider the following circuit from the Dunlop and Gutman paper on loadability. Consider the following problem: Referring to the circuit diagram, Given: R, X, B, X 1, X 2, θ 1, |E 2 |, |E S | Find: |E 1 |, θ s, |E R |, θ R Assume N S =N R =N=0. Provide a solution strategy for solving this problem. You must provide appropriate equations to be solved and you must describe a solution method. You do not need to implement the method.
