The ac power flow equations, voltage limits, and thermal limits are respected to ensure the obtained solution causes no static violation while ensuring network transfer capability. A scenario reduction technique using affinity propagation clustering is developed to reduce the number of scenarios and relieve the computational burden. A three-stage solution methodology is developed to solve the nonconvex constrained optimization problem, in which a two-parameter homotopy-enhanced methodology with a decomposition scheme is developed to reliably and quickly solve the online multiperiod power dispatch problem. The proposed three-stage solution methodology has been evaluated on several testing systems, ranging from a 30-bus system to a 3012-bus system with four time periods, and the numerical results are promising. 收起
