Modern Electrical Power Systems

introduction
Modern electrical power systems increase the efficiency of electrical power generations, transmission and distribution it also lowers carbon footprint for a greener world. It includes the ‘green generation’ of electricity by means of renewable energy.
In addition, 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.
