Dispatched Control for Normal Conditions on the HV-AC or Compound HV-AC-DC Systems

The Dispatched Control principle is developed to assure on line economic production of power including losses while maintaining system wide frequency and tie line load setpoints as well as the AC and, if present, the DC voltage profiles. New feasible algorithms are introduced for the reactive power and multiterminal DC system controls. Previously published papers [1], [2] have treated the reevaluation of the Dispatched Control of real power generation or AGC. It is advocated here to treat system security not on line but as part of unit commitment combined with on line active emergency control. A new "Transjection Model" for the compound multiterminal HV-AC-DC system is introduced which emphasizes structural properties of such systems and is instrumental in developing a system wide, uniformly structured Dispatched Control.
