Summary
This course focuses on the dynamic behavior of a power system. It presents the basic definitions, concepts and models for angular stability analysis with reference to transient stability, steady state stability and long term stability.Fundamentals related to voltage stability are introduced as well.
Content
Role of simulation for power systems operation and planningLoad-flow in steady-state balanced three-phase systems: Gauss-Seidel method. Newton-Raphson method. Active-reactive decoupling. Linearized method (DC flow).
Stability and dynamic behavior: Definitions: Steady-state, transient and long-term stability. General model of the power system. Direct methods. Time domain methods: partitioned approach, simultaneous approach, numerical integration methods.
Steady state stability and transient stability: Choice of generator and load models. Classical model of stability. Multi-machines stability. Application: case of one-machine connected to an infinite bus (equal-area criterion). Eigenvalues and eigenvectors applications.
Long-term stability: Simulation of the dynamic behavior of the electric power system at the scale of minutes or several minutes after a disturbance. Modeling: primary and secondary frequency control, generators and loads.
Design and operation of simulation software: Case studies using an industrial simulation software (Eurostag).
Keywords
Load-Flow calculation, steady state - transient - long term stability, direct/time domaine methods, classical model, equal area criterion, primary/secondary frequency control, eigenvalues and eigenvectors.
