Power System Planning and Operation

Course Description

Exploitation characteristics of electric power system. Operational system states (normal, transient, emergency, critical, restorative). Daily electric power system load curve. System load curve approximation. Load curves: weekly, monthly and annually. System operation planning (daily, monthly and annually). Analytical functions for system operation planning. Analysis and checking of realized system operation. Load Forecasting (parable method, second order polynomial method, xpotentially method, logarithm parable method, Gompertz method, logistic method, empiric equation). Unit scheduling. Midterm unit commitment. Load following. Energy imbalance. System reserve (ready-import, spinning, stand by quick start, stand by slow start). Interconnection. Power and energy exchange between systems. System island operation. System blackout and restoration. Analysis of recently system blackouts. Grid code.

Learning Outcomes
