This course is motivated by a direct need to understand what went wrong last summer in the Western United States when large portions of the interconnected electric power system experienced partial blackouts. The problems were primarily dynamic and, as such, strongly dependent on control and protection mechanisms in place. This scenario will be used throughout the course to motivate various portions of the material, as they get introduced. The challenge is to understand what went wrong (analysis) and if and how it could have been done differently by means of different control/protection and their coordination.
In addition, the industry is undergoing structural changes from being operated as one single monopoly to becoming a competitive industry, in which much of design and decision making is likely to be done in a decentralized way by the individual owners. The second part of the course relies on the general knowledge of dynamics and control studied in the first part of the course, and draws distinction in formulation of dynamic problems (both analysis and control) under restructuring. These are new problems, and, once formulated could lead to very challenging research concerned with system controllability and observability, implications on system stabilizations, and, moreover, the problems of (price) incentive controllability.Students interested in applied control and power systems are encouraged to take this course.
The emphasis this semester is on two general areas:
1. Dynamics and principles of control design (including protection) for
electric power systems.
2. Possible problem reformulations and solutions in a deregulated
industry.
Prerequisites:
6.689 assumes that students taking it are either familiar with the
material covered in 6.686 in the fall term '96, or have taken the course.
In other words, knowledge of the following topics
is expected (students willing to study this material at a fast
pace necessary to follow 6.689 will be given 6.686 lecture notes and the
course instructor will provide necessary guidance through this material):
1. Phasor calculus as a means of modeling power systems.
2. The overall structure of the system.
3. Physically-based models of classes of individual system components
(synchronous machines, transmission lines, loads).
4. Principles of hierarchical modeling and control of large
power systems.
5. Steady state analysis.
6. Steady state corrective actions.
Fairly strong background in dynamical systems is also assumed.
Topics covered:
6.689 is effectively a continuation of 6.686 with the emphasis on fast system dynamics, and control design principles for its regulation. The following topics will be covered:
Recapturing 6.686, objectives of 6.689.
Small signal models of a general electric power system; controllability and observability of these models; stability analysis; coherency in power systems; methods for model reduction.
Design principles of presently implemented (primary) control; system protection; new control technologies ( Flexible AC Transmission Systems (FACTS), HV-DC), modeling, protection and control.
Nonlinear dynamics of electric power systems; need for nonlinear control.
State of the art in nonlinear control of power systems; variable structure control for FACTS; feedback linerizing control for synchronous machines.
Dynamics in competitive industry; obligation to serve versus obligation to deliver, and its impact on system dynamics.
Price incentive controllability; control induced market power; economic value of controls versus their cost.
Control designs to mimic contractual obligations at an individual market player level, without affecting the others-- can it be done? Bidding for control.
