A mixed integer programming model for intra-day microgrid scheduling

A mixed integer programming (MIP) model, which consider coordination of active and reactive power, is put forward in order to solve microgrid (MG) energy management. Compared with the conventional model for MG economical dispatching, the linearized constraint model, such as active and reactive power output limitation of distribution generation (DG), is established. The numerical results of case studies demonstrate that the shorter the time interval to roll back in intra-day scheduling, the closer it gets to the actual scheduling plan. And the linearized model of considering DG´s active and reactive power output limitations is in line with the practical engineering.
