Optimal Planning for Building Integrated Microgrid System (BIMGS) for Economic Feasibility with Renewable Energy Support

Advancements in renewable energy technologies and their integration into the power system encourage their utilization in smart cities for sustainable development. In this work, optimal utilization of renewable energy sources (RESs) is presented for the building integrated microgrid system (BIMGS) under the smart cities environment. In this way, real-time optimal control can be done while feeding the building load. These types of system integration also provide self-sustainability to the building. In the proposed work, the building is considered to have four energy sources, these are, solar panels installed on the roof, small-scale wind turbines are also installed on the roof, some of the RESs units installed on the ground within the building premises, a storage system, and the main grid supply system. The storage system is placed within the premises of the building. The ratings of the resources are considered to meet building load only. However, the provision for a connected grid is also considered. One-year historic RESs data for the Roorkee area (coordinates 29.8543
^◦
N, 77.8880

E)) and the load demand data for a subarea of Roorkee are utilized for system planning. The analysis is accomplished to obtain optimal generation from various sources so as to meet the load demand optimal by formulating an optimal energy management problem.
