Abstract:
Traditionally, in many countries, electrical power industry has been struc-
tured in a vertically integrated manner. The generation, transmission
and distribution of electric power are totally controlled by large utilities within
the region of their operation, where these utilities are the only providers
of electricity. In such market scenarios, utilities have to operate within the
policies, guidelines and regulations of the government while being assured of
minimum pro t without any risk. This assurance has led to incompetent and
sluggish attitude in the industry with lack of motivation for technical innova-
tion, e cient management and customer focus. To overcome these drawbacks
of the monopolistic market, most of the utilities are getting restructured.
This work addresses some of the technical challenges encountered in the
restructured market such as optimal power
ow (OPF), determination of total
transfer capability (TTC), available transfer capability (ATC), transmission
pricing and congestion management. New algorithms based on di erential
evolution have been suggested to solve these problems and the results are
compared with other methods
