A convex model for optimal day-ahead dispatch considering wind generators and network reconfiguration

This paper proposes a mixed-integer quadratic programming (MIQP) model for optimal day-ahead distribution networks dispatch considering Wind Generators (WGs) and topology reconfiguration. Firstly, linearized current injection model is introduced for generators by a series of approximations. Then the day-ahead Switching Operations (SOs) of reconfiguration could be calculated in a linear form based on the fixed characteristic of network topology. Finally, the costs of power loss and SOs are minimized by our model while the linear constraints, e.g. nodal voltage (NV) constraints and branch current constraints, are considered. The simulation results on IEEE-33 system demonstrate that the proposed model is feasible and effective.
