A case study in the identification of best combination of energy resources for hybrid power generation in rural communities through techno-economic assessment

This paper illustrates techno-economic analysis on hybrid energy systems for a remote community near Gulbarga in Karnataka state, India, which is blessed with the best of solar radiation and wind velocity. In this paper, the possible combinations with solar PV, wind, and Battery Energy Storage System (BESS) are simulated for an annual period in HOMER (Hybrid Combination Model for Electric Renewable) software. The objective of the work is to identify the best combination among these hybrid energy systems based on the Net Present Cost (NPC), Cost of Energy (COE) and Levelised Cost of Energy (LCOE) and economic calculations with the input of community load data, seasonal data, and plant equipment data. The comparison is performed among the proposed systems based on economic energy parameters. The proposed configurations are simulated for residential and commercial loads and concluded that the NPC, LCOE, capital cost and operating cost of wind and BESS system is lower than the solar BESS and solar and wind BESS systems. Finally, the hybrid energy combination of wind and BESS system is more economically feasible compared to other designed models for the selected area and the NPC of the system is 0.696$.

Performance Evaluation of Lead Acid Battery -Backup Power System of Solar Hybrid Power Plant

This work is concentrated on determining and evaluating the performance of the lead acid battery energy storage system of the solar hybrid power plant existing at Bahir Dar University. Evaluating the performance of solar battery energy storage system and other integrated units in a stand-alone or grid connected solar power plants having prominent significance and contribution with respect to adapting and utilizing the indispensable solar power (PV) technology in Ethiopia. The battery performance evaluation was done by analyzing the long day performance data of the battery backup unit and by carrying out experimental discharging operation. The battery backup unit performance evaluation was done by analyzing the long day performance, the battery efficiency, charging factor, depth of discharge and capacity of the battery. The results shows that the battery was charged without being discharged a number of times. This can be the result of loss energy by self-discharge of the battery, or wrong setting in recording of input output values or failure of the Xtender inverter charger RCC - 02/03 recording, displaying and control units..
