Course Description:

CHAPTER – I: INTRODUCTIONPlanning and operational problems of power systems - review of economic dispatch andcalculation using B matrix loss formula - use of participation factors in on line economic dispatch.

CHAPTER – II: OPTIMAL POWER FLOW PROBLEMReal and reactive power control variables - operation and security constraints and their limits -general OPF problem with different objective functions - formulation - cost loss minimization usingDommel and Tinney 's method and SLP method - development of model and algorithm - MVARplanning - optimal siting and sizing of capacitors using SLP method - interchange evaluation usingSLP.

CHAPTER – III: HYDRO THERMAL SCHEDULINGProblems definition and mathematical model of long and short term problems - discretization -dynamic and incremental dynamic programming - methods of local variation - hydro thermalsystem with pumped hydro units - solution by local variation treating Pumped Hydro unit for loadmanagement and spinning reserve.

CHAPTER – IV: UNIT COMMITMENT AND MAINTENANCE SCHEDULINGConstraints in unit commitment – Spinning reserve, thermal Unit constraints, other constraints -solution by priority list method - dynamic programming method – backward and forward - restrictedsearch range - Lagrangian relaxation method – adjusting .- Factors considered in maintenancescheduling for generating units - turbines - boilers - introduction to maintenance scheduling usingmathematical programming.

CHAPTER – V: INTERCHANGE OF POWER AND ENERGYEconomy interchange between interconnected utilities – interchange evaluation with unitcommitment – Multiple – utility interchange transactions – Power Pools: The Energy Brokersystem, Allocating pool savings – Transmission Effects and Issues : Transfer limitations, wheeling,rates for transmission services in multiparty utility transactions – Transactions involving NonutilityParties.
