Now days lot of research is going on FACTS and its application on power system performance enhancement.
In this post let us try to understand the problem of Maximizing the loadability of the power system with and without incorporating the FACTS devices.
i) Maximum loadability without FACTS devices
If a problem is to be understood the title should be understood in the realistic way.
A Power System comprises of generators,loads , transmission lines and other devices ( circuit breakers ,capacitors. and lightning arrestors).
1.The generators have real and reactive power limits and a better voltage voltage profile is to be maintained.
2.The loads have to receive the scheduled power at a better voltage. The load voltage voltage should be within the allowable range . Normally it is between 90% to 110% of the base(rated) voltage.
3.The transmission lines have the MVA power flow rating .
It is known that the load on a power system is not certain and subject to change with time. The variation of demand with time is called the Load duration curve.
All the Load centers are having Maximum demand indicators which record the maximum demand on a day/week and year. From this the importance of the maximum load-ability can be understood.
The term Maximum load-ability can be defined as the maximum load that can be served by the power network without violating the voltage,power and line flow constraints.
This is an offline study done on the power system data to determine the maximum load supplied by the power system without violating the constraints.
A) what is the data is required to carry out this analysis.?
busdata,generator and linedata ( same like matpower data format)
