Power Grid Operation Training

Power Grid Operation Training

Power Grid Operation training course description

Power Grid Operation training course lays the basic foundations of generation plants (or generators), their control, concepts of economic dispatch, and power flow analysis. This course gives you sufficient knowledge about generator dynamics, and concept of stability in power system operation.

Power Grid Operation training course simply teaches you how the electricity is generated in power plants and what steps are taken in order to deliver the generated electricity to the customers with high reliability. Several control approaches are introduced for the generators in order to achieve stable operation of the power system. This course discusses the modern control approaches implemented for generators to maintain the voltage and frequency within the limits. This 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.

Through the power system operation training course, Newton-Raphson and Gauss iteration as two different solutions for the power flow analysis will be discussed.

Also learn about:

• Real-time Grid operation
• Automatic Generation Control (AGC) as a feedback control system that regulates the power output of electric generators to maintain a specified system frequency and scheduled interchange
• The area control error (ACE)
• Operational mode
• Constant Net Interchange
• Error in interchange over the tie lines
• Constant Frequency
• Frequency deviation only
• Tie Line Bias
• Tie Line Bias plus Automatic Time Error Correction
• Smart Grid operation
• Micro Grid operation

Finally, power system operation training course will briefly introduce the economic dispatch in power system including generator cost functions considering transmission lines and generator limits.
