Economic evaluation of a hybrid renewable energy system (HRES) using hybrid optimization model for electric renewable (HOMER) software—a case study of rural India

Abstract: This paper unveils a sustainable energy plan for optimal utilization of available electrical energy resources for an energy-deficient village. The chosen village is Nangal, near Barnala, Punjab, India. Primarily, the requirements of electric energy are recorded and elaborated for around 450 households. Aiming this, the potential to harness electric power and its effective utilization has been identified from the available resources of energy: biomass, agriculture waste and solar photovoltaic (PV) technology. In order to achieve this, a hybrid renewable energy system (HRES) model is proposed whose performance is evaluated by implementing it in hybrid optimization model for electric renewable (HOMER) software. HOMER software provides optimal solution for a commercial biogas plant for catering cooking gas demand. Also, a coordinated solution for solar PV-operated water pumps used for irrigation, village water supply and solar PV street lights is presented and analyzed. In this way, the accurateness of proposed model is investigated by estimating the optimal electric power demand and its economic benefits. It has been revealed that the computed cost of energy and total net present cost are $0.032/KWh and $76,837, respectively, by the parametric assessment of proposed HRES system. It is envisaged that the proposed model can be a road map for future research engineers in designing an effective energy utilization for villages.

Electrochemical Studies and the Surface Examination of Low Carbon Steel by Applying the Extract of Citrus sinensis

Abstract: The corrosion inhibition effect of citrus sinensis belonging to Rutaceae family has been analyzed on the low carbon steel corrosion in 0.5 M H2SO4 by using weight reduction estimations and electrochemical measurements. It is observed that the extract of Citrus sinensis acts like a mixed type corrosion inhibitor and its inhibition effectiveness increases on increasing the concentration. The best inhibition effect of the Citrus sinensis extract for low carbon steel in 0.5 M H2SO4 was obtained at 500 mg/L concentration. Further the Langmuir adsorption isotherm was used to check the adsorption behavior of the extract on the metal surface. The surface morphology of the low carbon steel is also studied by using scanning electron microscopy and atomic force microscopy.
