Incremental industrialization and urbanization is the cause of enhanced energy use as it increases building new lines more inductive loads. As a result, transmission system losses increased, magnitudes voltage profile values deviated from stated value, resulting in increased cost active power generation. To mitigate these issues, adequate reactive compensation line bus systems should be done. R...

This paper aims to design an optimal distributed multi-agent controller for load frequency control and optimal power flow purposes. The controller parameters are optimized using Grey Wolf Optimization (GWO) algorithm. The designed optimal distributed controller is employed for load frequency control in the IEEE 30-bus test system with six generators. The controller of each generator is consider...
