Demand Response analysis for distribution system

A group of customers connected to the present power grid are very much sensitive to the power interruptions and as well as power variations. Therefore it is the responsibility of the power utility to provide the reliable service and also in case of power curtailment, utility should promise as maximum as possible amount of power supply to all the connected loads of high priority customers and partial loads of low priority ones. The demand side management system used so far could take care of the consumer convenience to very less extent. There is some contribution towards demand response at the distribution feeder level and at the building area network level, but very less work has been done so far, about the substation level demand response. Therefore this paper proposes a substation management system, in which the demand limit can be allocated by Hierarchical Cumulative Voting (HCV) method based on the assigned weight to the respective consumers. The results show that, the demand limit can be assigned efficiently, which in turn can be used for Demand Response (DR) strategy, when the load exceeds the available power from the utility.
