Optimization of Grid-Photovoltaic and Battery Hybrid System with Most Technically Efficient Pv Technology after the Performance Analysis

Abstract

The performance assessment of renewable energy technologies, such as PV systems, are pivotal in planning for hybrid energy systems. This work clears the way for researchers to construct the best PV-based hybrid systems by first performing performance analyses metrics suggested by IEC 61724 on several PV technology options, and then choosing the most technically sound option. Next, using HOMER  software, construct a PV/grid and battery hybrid system with effective PV technology. The performance of three PV technologies i.e., monocrystalline silicon, polycrystalline silicon, and amorphous silicon is assessed to demonstrate how their performance varies depending on the location. Result showed that, (m-Si) has greater performance than  other two PV technologies, with yearly array yields of 5.26 h/day, reference yields of 6.18 h/day, and final yields of 5.18 h/day, a capacity factor of 14.31%, system losses of 0.076, and a performance ratio (PR) of 83.9%. The most effective configuration of the system under evaluation consists of a 72.8 kW PV connected to the grid and a 59.4 kW converter. The total NPC is expected to be Rs. $397,684 for the optimal configuration, costing Rs. $0,0493/kWh. The additional electricity in the best situation is 977 kWh, which is insignificant compared to system capacity.
