1.2 Load curves and load-duration curve (daily, weekly and annual) - load factor - diversity factor.

1.3 Importance of load forecasting and simple techniques of forecasting.

1.4 An overview of power system operation and control and the role of computers in the implementation. (Qualitative treatment with block diagram).

UNIT II REAL POWER - FREQUENCY CONTROL

2.1 Basics of speed governing mechanism and modeling - speed-load characteristics

2.2 Load sharing between two synchronous machines in parallel.

2.3 Control area concept LFC control of a single-area system.

2.4 Static and dynamic analysis of uncontrolled and controlled cases.

2.5 Integration of economic dispatch control with LFC.

2.6 Two-area system – modeling - static analysis of uncontrolled case

2.7 Tie line with frequency bias control of two-area system - state variable model.

UNIT III REACTIVE POWER–VOLTAGE CONTROL

3.1 Basics of reactive power control.

3.2 Excitation systems – modeling.

3.3 Static and dynamic analysis - stability compensation

3.4 Generation and absorption of reactive power - Relation between voltage, power and reactive power at a node

3.5 Method of voltage control - tap-changing transformer.

3.6 System level control using generator voltage magnitude setting, tap setting of OLTC transformer and MVAR injection of switched capacitors to maintain acceptable voltage profile and to minimize transmission loss.

UNIT IV UNIT COMMITMENT AND ECONOMIC DISPATCH
