An extensive qualitative and quantitative multi criteria analysis for a hybrid renewable energy system applied to tribal zone - based primary health centres, and maximizing the societal parameters

Abstract

Remote electrification enhances the quality of life quality of people in remote areas, with no access to electricity through distributed coverage of electricity. Due to the irregular and unbalanced fuel cost and impracticable expansion of the grid, hybrid integrated renewable energy sources become dependable substitute for remote electrification. The necessity of uninterrupted power dispatch is a prime factor for primary health centres, located in tribal and remote areas. This article proposes an integrated primary analysis like financial, production, quantity and environmental, applied to an optimum sizing of a hybrid standalone renewable energy source, which might be carried out in eight primary health centres, situated in the Gudalur Zone in Nilgiris District, Tamil Nadu, India. Four different criteria were inspected in this study, as standard loading, boost up loading, step down loading and complete renewable loading. In addition, every criterion was assessed with four kinds of PV tracking arrangements. The peak load requirement of power and energy, for eight primary health centres, was around 121.08 kW and 907.96 kWh/day respectively. HOMER Pro Micro-grid Analysis Tool was used, to analyze the different primary parameters of this study. The foremost financial parameters like COE (Cost of Energy) and NPC (Net Present Cost), could range from 0.102 to 0.118 $ per kWh and from 0.4047 to 0.5708 Million $ respectively. Annual energy production of solar PV could vary from 318.5 to 427.65 MWh. The main quantity parameter like percentage of excess electricity was obtained from 13.3 to 21.5% annually. The leading emission parameters like CO _2 and CO were reported to range from 1700 to 4502 and from 7.98 to 28.1 kg per year respectively. Generator and fuel parameters, key properties of energy storage and converter, were also analyzed extensively. In addition, sensitivity analysis and social parameters were also discussed in this study. The result of this work gives a conceptual and flexible design of structure, to make possible the continuous power supply to the remote tribal area - based primary health centres, under in all situations.
