Course Description:

The course concentrates on the development of a clear understanding of the philosophy of modern power system operations, and the role of energy management systems, their design, and actual implementation. Past and current practices, as well as trends in the state-of-the-art design of energy management systems, are surveyed. The basic components of an energy management system, namely hardware, software, user interface, and communications, are discussed in detail with emphasis placed on applications software and its practical aspects.

Power Network Topology Analysis

 Understand the concept of network topology analysis, develop software program to translate break-point model to bus-branch model for power flow calculation.

Power System State Estimation

 Use knowledge learned in state estimation to design and implement WLS algorithm for a 3 nodes test system.

Experiments on Power System Simulation Software

1)State Estimation

(1) Facilitate better understanding and interpretation of the state estimation results;

(2) Illustrate how bad data affect the estimate, and how they can be detected and identified;

(3) Explain what observable islands are, and how they are detected and possibly merged.

2) Understanding of Load Flow

(1) Basic bus models (i.e., slack, PV and PQ buses) and the network admittance matrix;

(2) Simulation of power grid operation, such as: generator power dispatch, break switching, load shedding, reactive power adjustment etc.;

(3)Sensitivity Analysis

3)Short-circuit Analysis

Performing short circuit analysis for positive, negative and zero sequences, unsymmetrical fault (Phase to ground, Phase to phase).
