Coordination of Economic Load Dispatch and Load Frequency Control for Interconnected Power System
Abstract This paper deals with the coordination of economic load dispatch and load frequency control concepts of the interconnected power system. The total change in the particular control area is shared by each unit according to their participation factor obtained from the calculation of the economic load dispatch. In this work, two control areas are considered, the first control area contains the combination of hydro, thermal and gas generating unit and in the second control area, it contains the combination of the thermal and hydro generating units. Integral controller is used for secondary controller for load frequency control mechanism. A digital simulation is used in conjunction with the genetic algorithm (GA) technique to determine the optimum parameters of the individual gain of integral controller. Three different types of performance indices are considered to measure the appropriateness of the proposed controller. The optimum values of the gains improve the dynamic performance of the controller and reduce the overshoot and maximum frequency deviation and net tie-line power flow deviation error for a particular load change. To show the effectiveness of the proposed controller, simulation result is shown in result and discussion section.
