Economic Dispatch & Grid Stability Constraints In Power System

Category: Aci Code Requirements And Specifications For Concrete Design, Construction And Repair Training

Course Description

This highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops.  This training course gives you sufficient knowledge about generator dynamics, and concept of stability in power system operation. Also, you will learn how electricity is generated in generators from an AC current supply and what intermediate steps are needed to deliver the generated power to the customers with high reliability.

This training course discusses the simplified generator models which are commonly used in dynamic stability studies. By taking this training course, the audience will learn the modern control approaches implemented for generators to maintain the voltage and frequency within the limits. The idea of primary and secondary frequency control/droop control in synchronous generators is included in the discussions. In order to increase the reliable operation of the system during the load changes, concept of power-angle stability and voltage stability (voltage collapse) are described in this training course. Moreover, alternatives for load restorations using tap changer transformers are also covered. This training course not only focuses on the generation side, but also covers the transmission level by introducing the concept of power flow as an advanced tool to calculate the operating points in the power system.  Different power flow formulation approaches including DC and AC power flow is discussed. To solve the power flow in the power system, Guass-Seidel, Newton-Raphson and fast decoupled approaches are introduced. This lays the basic foundations of generation plants (or generators), their control, concepts of economic dispatch, and power flow analysis.

This training course will feature:

  • Power generation characteristics, Economic dispatch problem and Thermal unit economic dispatch and methods of solution.
  • Optimization with constraints, using dynamic programming for solving economic dispatch and other optimization problems and Transmission system effects.
  • The unit commitment problem and solution methods.
  • Generation scheduling in systems with limited energy supplies, Production cost models, Automatic generation control and Interchange of power and energy.
  • Power system security techniques, Least-squares techniques for power system estimation, and Optimal power flow techniques and illustrative applications.
