“…For photovoltaic systems, the emission factor is the GHG emission rate of per unit electrical energy generated by the photovoltaic system [49]; the CO 2 -equivalent emission factors reported in the literature vary from 14 to 73 g/kWh [50]. The GHG emission factor 40 g/kWh has been used in applications of photovoltaic systems with batteries [51].…”

“…For battery systems to be used together with photovoltaic systems, the GHG emission factor represents the preoperation phase and is expressed in g/kWh with respect to the maximum energy capacity (in kWh) of the batteries; the value 200 kg/kWh has been considered in [51] for a battery lifetime of 10 years and has to be multiplied by the energy capacity of the battery storage system to get the overall mass of CO 2 emitted during the construction phase. This information is not directly translated into a GHG emission factor to be used during the battery operation, for example depending on the energy discharged by the battery.…”

In recent years, the production of renewable energy has increased continuously to reduce fossil fuel consumption and CO2 emissions and to increase energy efficiency. The challenge of industries is to integrate renewable energy systems into the existing power system of manufacturing industries. In the energy flexibility approach, the manufacturing energy demand is aligned with renewable energy availability, to improve the use of the renewable energy source. This paper aims to investigate a manufacturing system supplied by a photovoltaic plant coupled with a battery storage system. A basic storage model has been developed and implemented to pursue this issue. The model is applied in the simplified case of a manufacturing system composed of a cutting numerical control machine, which can adapt the cutting speed to align the power needed to the power supplied by the photovoltaic plant. However, the model can be extended to realistic production cases characterized by complex systems as long as the time evolution of energy consumptions are known in detail. The introduction of battery storage allows reducing the cutting speed fluctuations, improving the cutting life derived from the fatigue effect. This solution reduces the costs of the machine and improves the forecasting of the means needed for the manufacturing system. Finally, a detailed analysis of greenhouse gas reduction is discussed.

“…The hybridization of the power system with multiple sources can assist the MGOs to overcome the intermittency of solar resources and maximize the efficiency of power supply and ensure the availability of electricity at all‐time 10 . As a measure to optimally utilize the aforementioned resources, it is imperative to use multiple power sources in order to overcome the weakness and drawbacks of a single technology 11,12 . This will help the MGOs to optimally utilize RERs and reduce the COE, net present cost (NPC), GHG emissions and fuel consumption 13 .…”

Summary The utilization of renewable energy resources (RERs) in the traditional power system has gained a global recognition owing to their technical, economic and environmental benefits. The techno‐economic analysis of a microgrid system that consists of diesel generator (DG), methanol generator (MG), photovoltaic (PV) and battery system (BS) is implemented in this study to evaluate the performance of the power system. The feasibility study of the power system is implemented by using HOMER application tool and meteorological data provided by the National Aeronautics and Space Administration. The analysis indicates that PV‐DG‐MG‐BS microgrid system is the most optimized configuration based on the net present cost (NPC) of $213 405.4, cost of energy (COE) of $0.256/kWh, renewable fraction of 88.6%, diesel fuel of 3055 L/y and DG operating hours of 1037 h/y. The results obtained from the optimized configuration translate to a substantial reduction in NPC, COE, diesel fuel and operating hours of DG when compared to the base case study. This indicates that the combination of DG, PV, MG and BS in a microgrid system is the most economical configuration to achieve a feasible result. Moreover, sensitivity analysis is carried out to investigate the impacts of solar radiation, load demand, fuel cost and inflation rate on the performance of the power system. The results obtained from the study clearly prove the effectiveness of using RERs to increase the sustainability and performance of the power system. This improves the standard of living and economic activities in areas where the microgrid systems are sited.
