Dispatching power and ancillary services in autonomous network-based power systems

Competition is being introduced in the electricity markets worldwide. In addition, large penetration of distributed generation introduces new players into the markets and significantly increases the uncertainties in the system. The concept of autonomous power networks is a realistic approach to deal with increased uncertainty and complexity in future power systems. An autonomous power network is the aggregation of producers and consumers presented in the overall power system as one unit. This paper formulates the autonomous network dispatching optimization problem in rather general form and illustrates its efficiency. The number of trade-offs that are included at the forward time energy and ancillary service markets are outlined and discussed.
