An energy management software for smart buildings with V2G and BESS

This paper presents the results of a research activity in the framework of electric load managementin buildings. The buildings are supposed to be smart; they are connected to the electric network butthey are also equipped with PV plants for integration of the electric energy request with the relevantstorage batteries. The idea behind is to use batteries of electric vehicles (present in the parking areasof the buildings) as supplementary storage systems. An algorithm is discussed, based on optimizationtechniques, that allows maximizing the number of electric appliances that can be fed in conditions ofpower limitation. The algorithm is purely numeric, and has been built with the idea to implement it in asoftware package that has been produced by the authors. Finally, a case study is presented which allowsevaluating the reliability and the effectiveness of the proposed algorithms and of the software.
