Case Study: What’s the buzz on Smart Grids 1) How do smart grids differ from the current electricity infrastructure in the United States? The main difference where the smart grids differ from the current electricity infrastructure in the United Sates is that there is no information currently available as to how much energy/electricity is being used and where it is being used. In simple words it can be said that currently there is no exchange of information between the provider and the consumer

INTRODUCTION Open- and closed-loop transfer functions have certain basic characteristics that permit transient and steady-state analyses of the feedback-controlled system. Five factors of prime importance in feedback-control systems are stability‚ the existence and magnitude of the steady-state error‚ controllability‚ observability‚ and parameter sensitivity. The stability characteristic of a linear time-invariant system is determined from the system’s characteristic equation. Routh’s stability

Kleinrock was born into a Jewish family in Manhattan on June 13 1934. Kleinrock’s interest in electrical engineering began at the age of 6 while reading a superman comic book. When the young engineer reached the centerfold he stumbled upon a paper showing him how to build a crystal radio. Struck with awe and curiosity he began t gather the material
