EXAM 2 SUMMARY • Exam format: • Closed book, closed notes • Calculators allowed, no communication devices. • Some computation; could be other kinds of questions (T/F, multiple choice, fill-in-blanks, short answer). • Suggested study approach: • Make sure you know how to solve all HW. Please check the solutions! • Review all in-class materials • Review assigned book chapters
EXAM SUMMARY • Exam coverage: • AGC • Primary control • Secondary control • CPS1, CPS2 • Cost curves • Heat rates & efficiency • Marginal vs. Average • NGCC Units & convexity • EDC • EDC with losses/penalty fctrs • LPOPF • Formulation (offers/bids) • LMPs • Effects on congestion Be able to obtain transfer functions from block diagrams and get steady-state values from transfer functions. Know what happens after a MW imbalance. Solution via closed form and Lambda search.
EXAM SUMMARY • Exam coverage: • Nonlinear OPF • Solution by grad search • Solution by Newton • SCOPF • Preventive • Fully corrective • Preventive-corrective • SCUC • Formulation • Integer & dynamic (inter-temporal constraints) • Significance/meaning of constraints • B&B • Basic concepts • How to branch, how to bound Formulation and physical understanding. Use of GSFs and of Effective GSFs.
