This document discusses a project to develop a Simulink model of a two-area load frequency control system using different controllers like PID, PI, fuzzy logic controller. The dynamic response of the two-area load frequency controller will be compared for different controllers. The objective is to control the frequency of an interconnected power system as the load varies which changes the speed and frequency of the generating unit. An appropriate controller must be designed to keep the system frequency within permissible limits.

2. Abstract:
• The load frequency control plays an important role in an
interconnected power system.
• The objective is to control the frequency of an interconnected
power system.
• Since, as the load varies speed also varies which in turn changes
the frequency of generating unit.
• So an appropriate controller must be designed to keep the system
frequency within permissible limits.

3. • In this project, Simulink model of two area load frequency
control will be developed by using Matlab/Simulink software.
• In this project the Simulink model of load frequency control
(LFC) will be simulated using different controllers such as
I, PI, PID and fuzzy logic controllers for different loads.
• The dynamic response of two area load frequency controller for
different controllers will be compared.

4. Problem Identification:
• The developing countries are facing energy crisis
continuously in spite of the rapid increases in the power
sector.
• Still there exists a wide gap between the demand and the
supply which hampers the overall development.
• Today the power engineers including the
planners, economists and technologists are worried and
thinking the ways to meet these challenges keeping in view
the numerous constraints.

5. • The operation of power systems as an interconnected system
usually leads to improve system security and economy of
operation.
• In addition, the interconnection permits the utilities to transfer
loads to the most economical sources of power.
