AUTOMATIC GENERATION CONTROL OF INTER-CONNECTED POWER SYSTEM

Abstract

Load frequency Control (LFC) is used for many years as part of Automatic Generation Control (AGC) in power system around the world. In a mixed power system, it is usual to find an area regulated by thermal generation or gas generation or in combination of both .A detailed literature search shows that there is a great need to improve the control strategy to achieve good performance of the mixed system in the transient mode. This Project report highlights the Control performance analysis of three area-interconnected system. It has been done by the use of integral controller and optimal control design. The three area-interconnected systems is simulated and studied through Matlab’s Simulink software. In the following study, performance of AGC for Thermal, hydro and gas turbine based power system is examined on the application of Integral Controller & Optimal Controller.
