Inspection and Optimization of Size and Cost of Increased Penetration in a Hospital Building Load with Minimization of Carbon Emission for an Actual Load: Case Study

India ranks fourth in solar generation and fifth in global energy map with massive increment in installed capacity since last ten years. The renewable energy potential of India is diverse and changes in each geographical zone. This diversity creates issues with energy management policies. To integrate hybrid renewable resources, it is necessary to evaluate the proper size and cost of these resources but both these factors are dependent on local weather conditions. The proposed study is based on the optimization of hybrid renewable and non- renewable energy systems for a hospital building load. For this Homer software has been used to evaluate minimum cost and size of proposed system. A simulation model with different energy resources has been presented in this study. It has been found that it is feasible to plan a stand-alone system for the given load at the selected location. The optimized model includes solar PV, wind and battery storage system which has been simulated for On-Grid and Off-Grid optimization. A techno-economic study has been presented in this work which suggests minimum cost and exact size with reduced carbon emission. It shows that cost of energy 0.16$ and NPC 2.17 ml$ may be achieved with proposed models.
