Techno-economic investigation of a grid-connected photovoltaic-biomass hybrid system for shaping the sustainable electrification in Ayeyarwady delta of Myanmar

This article presents the techno-economic investigation of the Grid-connected Hybrid system by harnessing the abundant potentials of Renewables in Ayeyarwady Delta of Myanmar. The focused village in this study, Ma Yan Chaung, is geographically situated at latitude 16 degrees 35'7"N and longitude 94 degrees 54'7"E. Its annual average Solar GHI (Global Horizontal Irradiation) is 5.08 kWh per m(2) per day. It is included in the electrified (Grid arrived) village tract of Moke Soe Kwin and located in the Myaungmya Township. Site survey to that village was conducted in May, 2019. According to the collected data, the available Biomass is 480 tonnes per day and the estimated demand of the focused village is 2296 kWh per day with 361.7 kW peak. The thousands of different models are simulated in the powerful Microgrid tool, HOMER (Hybrid Optimization of Multiple Energy Resources) Pro (version 3.13.3). Then, the feasible Grid-connected system is proposed with 100 kW PV; 1,800 kW Biomass; 45 kW Converter; total NPC (Net Present Cost) 4,255,082 $; levelized COE (Cost of Energy) 0.01575 $ per kWh; Initial Capital 524,000 $, and Operating Cost 219,337 $. Annual Energy Sold to Grid is 15,045,299 kWh and Average Monthly Energy Sold is 1253775 kWh. The simulated results significantly demonstrate the good performance and the available benefits of the proposed system. Moreover, this system can shape the Sustainable Electrification to tackle the Climate Crisis in Ayeyarwady Delta Region of Myanmar.
