Optimization of automatic generation control and economic load dispatch for two area six unit interconnected power system

الملخص EN

This paper proposes an integrated Economic Load Dispatch (ELD) and Automatic Generation Control (AGC) for interconnected power systems.

Based on their participation factor determined from the economic load dispatch calculation, each unit shares the total change in the same control region.

In this study, two control areas are considered.

Three thermal units are located in each control area.

An integral controller (I) is only used for the AGC mechanism's secondary controller and is used for the primary controller for the ELD mechanism.

An Improved Grey Wolf Optimizer (IGWO) technique is used to evaluate the optimum parameters of the integral controllers for primary and secondary controllers.

An integral time square error (ITSE) has been used as the objective function to tune the suitability of the proposed controller gains.

The simulation results demonstrate that the integrated AGC with ELD has the superiority in reducing the overshoot and fast steady state compared with AGC only.
