Abstract: The energy system optimization in internet of things era is a critical task considering high number of active participant and their cyber security and privacy. In this paper, optimization of an energy system is discussed that can be expanded to include other characteristics of a smart grids such as communication systems and the constraints of consumers. This paper investigates the cost viability of installing photovoltaic and battery systems at an Australian educational institute to offset the peak demand and reduce total electricity price. The results from this cost benefit analysis shows that considerable savings in energy purchased will be achieved when panels are installed on North facing rooftops only for a large scale photovoltaic system. It has also been shown that batteries are not economically feasible for this case as their costs are high.

Keywords: PV, battery, educational institute, cost benefit analysis, optimization, HOMER, net present cost
