An OPF based tool for demand relief programs

This paper proposes a dynamic optimal power flow (DOPF) framework to assist the implementation of consumer participation programs aimed at mitigating the effects of critical operating conditions on the quality of power supply. The proposed DOPF-based tool allows the representation of consumer operating constraints and provides important subsidies to the implementation of consumer participation programs, such as the proper selection of the loads to be reduced and the corresponding reduction of MW/MVAr consumption required to alleviate the abovementioned effects. The explicit representation of transmission losses and reactive power flows into the problem formulation enhances the ability of the DOPF tool to devise adequate demand participation strategies. The application of the proposed method to implement demand participation programs is illustrated through its application to two test systems, including a realistic system based on the power network of a Southern Brazil power utility.
