Modern Electrical Power Systems




Introduction:

Modern electrical power systems increase the efficiency of electrical power generations, transmission and distribution it also lower carbon footprint for a greener world. It includes the ‘green generation’ of electricity using renewable energy.

The introduction and merits of the Smart Grids and Micro Grids are also discussed in the seminar. The determination and control of fault levels, active power, reactive power, voltage, and frequency are essential in a modern electrical power system. Power quality issues are also addressed by modern mitigation techniques.

This course will ensure power system stability incorporating the Flexible AC Transmission System (FACTS) which has evolved to a mature technology with a high power rating. This technology has widespread application, became a top rate, most reliable one, based on power electronics. The main purpose of these systems is to supply the network as quickly as possible with inductive or capacitive reactive power that is adapted to its particular requirement, while also improving transmission quality and the efficiency of the power transmission system.
