A Steady-State Model of the Photovoltaic System in EMTP
نویسندگان
چکیده
-This paper presents a steady-state model of a gridconnected photovoltaic (PV) system using Electromagnetic Transient Program (EMTP) MODELS. Recently the PV system has been introduced in power systems. The previous PV generation was used only to supply small loads or for home use. Nowadays, installations of grid-connected PV systems are increasing due to several advantages compared to standalone PV systems. Depending on the characteristics of the PV system and the power quality issues of connecting PV systems to the grid, a detailed and integrated analysis of grid connection is necessary. Through modeling, we should be able to determine the potential energy benefit and analyze the power quality of grid-connected PV systems. The steady-state analysis is necessary to analyze the distribution system with PV systems in transient conditions. PV generators or PV arrays are formed by combinations of parallel and series connections of PV modules. The evaluation and modeling of PV systems are performed with data from real PV modules in EMTP/ATPDRAW MODELS. Results of the modeling and PV characteristics are described.
