The security constrained unit commitment considering the interactive impact of price based demand response

Abstract

Since the demand response play a more and more important role in smart grid, a security constrained unit commitment model considering the interactive impacts of price based demand response is proposed. First, the price based demand response is integrated with the basic security constrained unit commitment (SCUC) model, then the interactive impacts are considered. In the user side, the comprehensive electricity satisfaction is considered and the power flow balance is considered in the system side, which forms a more safety model. The case study on the six bus system demonstrates that the interactive impacts constraints can guarantee the economic effectiveness of DR without affecting users' feeling, and simultaneously optimize the power flow distribution to decrease the risk of cascading failure.
