Frequency analysis of multi-source single area power system using WCA algorithm

Automatic generation control (AGC) is becoming an essential part of complex power system in order to give good quality power to consumers. When there is load fluctuation happening in power system, it leads to frequency unbalance in power system and due to this complex power system become unstable. To avoid this kind of problem AGC and load frequency control method is used for balancing the power system frequency. In this paper a multi-source single area power system has been presented and is studied using the statistical analysis. In this work proportional-integral (PI) controller has been used as area controller. In order to optimize controller, WCA algorithm has been used. Load frequency control system was simulated on MATLAB with the load disturbances of 0.01 p.u. in all the areas. In this work multi-source single area power system LFC has been used for simulation purpose.
