Optimized Coordinated Economic Load Dispatch and Automatic Generation Control for an Interlinked Power System

摘要

The results are obtained by simulation of interlinked power system based on both single- and two-area system under dynamic load conditions with varying frequency. Power system is coordinated with automatic generation control (AGC) and economic load dispatch (ELD) to optimize the load variation by minimizing frequency deviation. Four optimization techniques are used and compared based on different criteria. The technique showing least error is described as best method in this scenario. Here, the observations show that firefly algorithm gives the optimum result in both the cases as the values of integral square error, integral average error, and integral total average error obtained among all the methods are the least; so it can be suitably applied in order to minimize the frequency deviation. Further, the results of ACO, HS, and GA are also compared. This work can also be extended to three control area power system to optimize fluctuating load demands and to improve the quality of power supply in different circumstances.
