UNIT I INTRODUCTION
System load variation: System load characteristics, load curves – daily, weekly and annual, load duration curve, load factor, diversity factor. Reserve requirements: Installed reserves, spinning reserves, cold reserves, hot reserves. Overview of system operation and Control: Load forecasting, techniques of forecasting, Indian power sector – Past and present status: Recent growth of power sector in India – An overview, A time line of the Indian power sector, Players in the Indian power sector, basics of power system operation and control.
UNIT II LOAD FREQUENCY CONTROL
Need for frequency and voltage control – Plant and system level control – modeling of LFC of single area system – static and dynamic analysis – LFC of two area system – static and dynamic analysis – Tie line bias control – development of state variable model of single and two area system.
UNIT III HYDROTHERMAL SCHEDULING PROBLEM
Hydrothermal coordination – hydro electric plant models – short term and long term scheduling problem – gradient approach – Hydro units in series – Hydro-thermal scheduling with pumped hydro plant: Scheduling of systems using Dynamic programming and linear programming.
UNIT IV UNIT COMMITMENT AND ECONOMIC DISPATCH
Statement of Unit Commitment (UC) problem; constraints in UC: spinning reserve, thermal unit constraints, hydro constraints, fuel constraints and other constraints; UC solution methods: Priority-list methods, forward dynamic programming approach, numerical problems. Incremental cost curve, coordination equations without loss and with loss, solution by direct method and λ-iteration method. Gradient method- Newton’s method – Base point and participation factor method. Economic dispatch controller added to LFC control.
