主 题：Day-ahead optimization energy management strategy forecast errors microgrids community realtime compensation strategy
摘 要：The advantages and promoting applications of the microgrids community(MGC)allows for a critical step being taken toward a smart *** energy management strategy(EMS)is essential to intelligently coordinate the operations of the *** paper presents a multi-time-scale EMS consid-ering battery operational modes for grid-connected *** proposed strategy consists of two modules:day-ahead integrated optimization and realtime distributed *** first module aims to minimize the operational cost of the MGC considering battery free-overcharging *** problem is solved by the mixed integer linear programming(MILP)sim-ulating two charging/discharging modes:limited-current mode and constant-voltage *** second module is installed in local MGs to correct the optimizing deviations of the day-ahead static scheduling,which are caused by predicting errors of renewable energy and *** main contribution of this work is integrating the advantages of global optimization of the centralized method and the fast computing speed of the distributed *** results prove the proposed EMS is feasible and *** computing time at each updating step is reduced by 75%on average,which has the potential to be adopted in engineering.
