Development of EMS for Microgrid for Office Building

Abstract

The concept of microgrid (MG), which can integrate a number of distributed generators and realize high efficient energy management, is attracting great attentions. The authors are investigating the feasibility and effectiveness of DC supplying MG (DCMG) for an office building, from the viewpoint of environmental-load reduction. In this paper, an optimal scheduling for DCMG, which can consider the PV forecast errors and their impacts on operation performance, is introduced. Additionally, second time interval operation algorithm is also introduced. Effectiveness of the proposed algorithm is evaluated through computational simulations using the actual data.
