About the importance of simulationLet’s consider the design of an aircraft.Cost Billions$ to design and manufacture.
Can we wait until the first flight test to verify it actually fly?
Consider now a large power gridAgain, it can cost $billions to design
Can we wait until commissioning to make sureit is stable and robust?

MODEL OF POWER GRID
It is sometimes difficult to test a power systems device in its working environment or in real life condition.
Solution: One can connect a real network device(ex: a FACTS controller) to a simulated power grid
Other common applications: statistical testing, correlation testing

In last decades, the modeling & simulation technology has developed into a comprehensive technology system and became a common and strategical technology.
The technology has been successfully applied into various top High-Tec areas such as: aerospace, electric power, information, biological, material, energy, production; and various fields such as: industry, agriculture, business, education, military, traffic, economics, medical & life science, entertainment and services, etc.

Impact of Real Time Digital Simulation Techniques
The World Standard for Real Time Digital Power System Simulation
Real time digital simulation• represents an important advancement in the understanding
of power system operation and performance • allows more organizations to establish affordable and
manageable in-house simulation facilities• combines the accuracy of digital models with the real time
response of traditional analogue simulators• provides a mechanism to rigorously study and test the
performance of new and existing protection and control devices prior to installation in the actual power system
• provides detailed knowledge of power system performance before, during, and after an event
• increases confidence and reliability in the design, implementation and operation of the electrical network and its complex components
