The active network challenge (geplant)

There are numerous efforts to determine if distributed generation (DG) can benefit local electricity consumers by reducing the costs and increasing the reliability of distribution service. But there is a lack of experience with integrating DG into the utility planning process and grid operations. Utilities have not used DG as a tool so far because of unknowns relating to predictability, dispatchability, control, size of potential resources relative to the need, cost and technology reliability. Undoubtedly the greatest challenge facing network operators in the future will be to ensure that the transition from passive to active network operation is adequately supported by appropriate control and protection systems. In this respect, control of both voltage and power factor are key priorities. This includes both controls applied to active networks and controls applied directly to DG. Closely associated with power factor control is the control of load flows in active distribution networks.
