Abstract

In order to solve the problems of nonlinearity, nonconvexity in the traditional Security Constrained Unit Commitment (SCUC) model, this paper constructs a fully linear unit commitment model based on power-voltage sensitivity. Based on the power-voltage sensitivity approach, the effect of the node injected power on the node voltage is analyzed to derived linearized node voltage magnitude constraints. The linearized expressions of branch power flow, node power balance and unit active-reactive power coupling constraints are obtained by Taylor series and auxiliary variable methods, ultimately yielding a fully linear unit commitment model. Simulations on IEEE 30-node and 118-node systems validate the effectiveness of the proposed model.
