Renewable Energy Aware Cost Assessment for Green Data Center with Hybrid Energy Sources

The skyrocketing research interest in the area of green data center (GDC) under the cyber-physical system (CPS) has been emerging over the last few decades. The over expanding need of information communication technology (ICT) and gigantic internet data service demand has led to an increase in the number of data center results a massive electrical energy expenditure for GDC. Therefore, reduction of energy consumption as well as the minimum cost of electricity (COE) with the desired quality of service (QoS) has been identified as an exciting research topic in the ICT sector. This paper proposes an energy sustainable hybrid power supply solution for the GDC endeavoring to curtail grid electricity usage and fuel consumption with the least possible net present cost (NPC) over the project duration of 10 years. The proposed framework is fed with both renewable energy (RE) sources such as wind turbine (WT) and solar photovoltaic (PV) array and non-renewable energy sources such as diesel generator (DG) in conjunction with adequate battery units. A hybrid optimization model for electric renewables (HOMER) software adopted to carry out an extensive simulation concentrating in optimum system design architecture and corresponding energy evaluation, cost assessment and carbon footprint analysis under a wide range of CPS scenarios.
