On the inter-area optimal voltage and reactive power control

Omid Alizadeh Mousavi

Scheduling voltage and reactive power is one of the major problems and concerns of the Transmission System Operators (TSOs) especially after deregulation of power market. Due to locally provision of the reactive power resources, each TSO has developed its ...
