However, the emulation methods often require nonlinear PV modeling, which may have long computational times. Hence, an effective real-time emulation method should minimize the computation time while maintaining high accuracy. This work compares different PV emulation techniques to investigate the advantages and disadvantages of various methods for real-time hardware testing. First, a literature survey compares the type of PV model, interface used, controller, and real-time technique adopted to emulate a PV model's current-voltage characteristics. Then, the PV model emulation methods are compared using a low-cost real-time emulator (RT Box 1), and computational cycle times are measured. The target application is to emulate a PV panel over various days and test the system control algorithm in real time for a PV microinverter with an integrated battery.Computation time | Nonlinear solver | Photovoltaic model | Real-time emulation | Renewable energy[SDGs]SDG7conference paper10.23919/ICPE2023-ECCEAsia54778.2023.102139342-s2.0-85170638619https://api.elsevier.com/content/abstract/scopus_id/85170638619
