What you'll learn

  • Describe the structure and operation of interconnected power systems, including voltage levels, frequency control, reliability criteria and load characteristics
  • Represent multi-voltage systems in per unit, change bases, and model transformers including off-nominal taps and three-winding units
  • Model synchronous generators with internal voltage and reactances, apply power-angle relations, interpret capability curves and compare them with inverter-based resources
  • Calculate transmission line parameters and apply short, medium and long line models, surge impedance loading, power-angle relations and compensation
  • Explain the link between reactive power and voltage, select reactive compensation and tap-changer controls, and assess voltage stability with PV and QV curves
  • Formulate and solve load flow problems with the bus admittance matrix, Newton-Raphson, fast decoupled and DC methods, and perform contingency analysis
  • Perform economic dispatch with limits and losses, explain unit commitment and optimal power flow, and calculate locational marginal prices under congestion
  • Apply the swing equation, equal-area criterion and numerical simulation to transient stability, and analyze small-signal oscillations and their damping
  • Calculate symmetrical and unbalanced fault currents using the bus impedance matrix and symmetrical components, and apply the results to grounding and equipment ratings
  • Build sequence networks with transformer connections and phase shifts, compute unbalanced fault currents and voltages throughout a network, and assess grounding and overvoltages
  • Analyze inertial response, governor droop, AGC with area control error, reserves, low-inertia operation and underfrequency load shedding
  • Apply resource adequacy, planning standards and interconnection requirements, and carry out a system study for connecting a new resource
