Abstract

Every year, solar panels experience a decline in production, so it is necessary to evaluate the degradation and performance of multicrystalline silicon (mc-Si) solar panels in tropical climate conditions. This research uses SEAWARD PV 200 (Complete Kit) to measure solar panel output data, which is then analyzed using the translation method according to IEC 60891 Procedure 1 to determine Standard Test Conditions (STC). The translational results showed a solar panel degradation rate of ±1.16% per year. Performance evaluation using the linear regression method revealed that a tropical climate that increases the temperature of the solar panel increases the percentage of degradation, where every 1°C increase in temperature causes an increase in degradation of approximately ±0.15%.

Abstract

This study discusses the optimization of the placement and capacity of Photovoltaic (PV) and Battery Energy Storage System (BESS) units in the IEEE 33-bus distribution system using the Hybrid Flower Pollination Algorithm (FPA) and β-Hill Climbing (βHC) or HyFPAβHC methods. The primary objective of this research is to enhance the performance of the distribution system by reducing power losses and improving the voltage profile. Based on the optimization results, three PV units with capacities of 749.3 kW, 577.5 kW and 620 kW were optimally placed at buses 8, 13 and 20, respectively, while one BESS unit with a capacity of 1112.4 kW was installed at bus 24. Simulation results indicate that the integration of PV and BESS significantly reduces the total system power losses from approximately 50 kW on several main feeders under the base condition (without Distributed Generation) to below 5 kW after optimization. In addition, the voltage profile improved from a minimum value of 0.92 p.u. to a stable range of 0.98–1.0 p.u. Furthermore, the integration of PV and BESS contributes to mitigating power fluctuations, enhancing energy efficiency, and improving the reliability of the distribution system operation. Therefore, the HyFPAβHC method is proven to be effective in determining the optimal configuration of PV and BESS units to improve the technical performance of electrical distribution systems.
