ELECTENG 731 : Power Systems

Postgraduate course

Project description

This course is an introduction to fundamental aspects of power systems theory and analysis. It includes review of the modeling of components of an integrated power system. This is followed by analysis of power systems, which provides the foundation of understanding how modern power systems work. The analysis part includes network analysis concepts and techniques for load ?ow, fault, stability studies, market analysis. 1. Power Systems Fundamentals & Load Flow Analysis Review of power systems fundamentals & per-unit systems; SCADA, EMS, DMS & Smart Grid; Development of non-linear load flow equations; bus admittance matrix; classification of bus types; solution techniques; voltage and power flow control; general algorithms for the solution of the load flow equations-the Gauss Seidel and Newton Raphson techniques; Approximations of Load Flow. 2. Fault Analysis Types of faults, use of Thevenins and Superposition Theorems for fault analysis; symmetrical faults and fault levels; matrix methods for the analysis of faults in large order systems; asymmetrical fault conditions and the symmetrical components transformation technique for analysis; sequence networks and the application of the connection methods; matrix methods extended to the analysis of asymmetrical faults in larger order systems. 3. Power Systems Transient Stability Analysis Basic concepts of power systems stability; the dynamics of the synchronous machine in the network; the electromechanical equations; coherent machines; a two machine equivalent system and representative swing equations; the swing equation for a single machine on infinite bus-bars; the Equal Area Criterion; critical clearing time and angle calculation. 4. Power Systems Modeling, Pricing and Optimization DC load flow models; Review of Linear Programming; Electricity Markets; Locational Marginal Pricing (LMP); New Zealand Electricity market & NZ Scheduling Pricing & Dispatch (SPD) model; Financial transmission Rights (FTR); Emerging Market Mechanisms for addressing Scarcity and Demand Side Participation; Mixed Ownership Model (MoM) for Generation.
