Development of energy management system for DC microgrid for office building:-Day Ahead operation scheduling considering weather scenarios-

摘要

In recent years, distributed generators (DG) with renewable energy (RE) are introduced to electric power systems for saving CO emission. Installation of DGs in user-side leads to the local demand and supply system, called microgrids (MGs). Since the some of DGs work in DC, advantages of DC supply system over the AC might be emphasized The authors are investigating the merits of DC microgrid (DCMG) using the actual DCMG for an office building. Operation of the DCMG is organized by an energy management system (EMS). This paper proposes an optimal scheduling algorithm implemented in the EMS. Simulation using the actual demand data shows that the proposed scheduling algorithm can save 0.3 % CO emission during the simulation terms.
