Description

This course studies detailed aspects of power system operations and control, scheduling, and steady state security assessment and operations in the competitive environment. The emphasis is on the analytic and computational aspects of problems that arise in system operations and control. Papers of interest are reviewed and discussed.

Topics

  • Overview of power system operations and control: the basic objectives of security and economics in power system operations and control; security analysis framework - scope, objectives and implementation; role of the EMS (energy management system)
  • Optimal power flows: review of optimization; economic dispatch problems; formulation of optimal power flow problem; solution methods; objective functions and representation of constraints; security constrained OPF; applications to dispatch and rescheduling; pricing information and spot pricing; role of reactive power
  • Resource scheduling and commitment: nature of resource scheduling problem; time hierarchies; objectives and constraints; key functions and their interrelationships; unit commitment and hydro-thermal coordination; solution approaches using DP and Lagrangian relaxation; role in EMS
  • State estimation: fundamental notions; static state estimation - role and formulation; the least squares state estimation solution; constrained weighted least squares estimation; measurement requirements; observability; bad data identification/ detection, analysis and processing
  • Electricity restructuring: transition from monopoly to competition -paradigms, organizational structures and regulation; competitive electricity markets; market design; interrelationships between various markets; impacts of restructuring and competition; unbundling; nature of transmission services; congestion management; ancillary services; informational needs
