This document discusses optimization in power systems. Optimization aims to find the maximum and minimum values of functions, and can be used to optimize various systems including power networks, transportation, and more. In power systems specifically, optimization becomes important as systems grow larger and more complex over time due to increasing demand. Optimization techniques can save power utilities hundreds of millions annually through reduced fuel costs and improved reliability while meeting environmental standards. The key goals of optimization in power systems are minimizing generation costs and maximizing social welfare while satisfying operational constraints.

2. What Is Optimization?
• Optimization is the mathematical discipline which is
concern with finding the MAXIMA and MINIMA of
function, possibly subject to the constraints for
continuous and differential functions.
• It is derived from the Latin word “Optimus”.

13. Optimization In Power System
Power system engineering has the longest history of
development among the various areas of electrical
engineering.
Power system are getting larger and more complicated day
by day because of:
>>Increase of load demand
>>Fossil fuel demand of thermal power plants

14. When the Power Systems are getting larger and more complicated
day by day then their will be some limitations like:
>>Rising costs
>>Rising emission into the environment
Therefore, optimization is become essential for the operation of
power system utilities in term of:
>>Fuel cost saving
>>Environmental preservation
