Modeling and Simulation of Ground-Mount PV Power Plant for Different Scenarios

This paper focuses on modeling and simulating a 1 MW photovoltaic (PV) power plant in the southern region of Bosnia and Herzegovina, specifically near Mostar. The study evaluates ten different scenarios, considering various tilt angles, interrow distances, DC/AC ratios, and azimuths, to analyze power generation and other performance metrics. Six scenarios use a 36° tilt angle, with interrow distances of 8 or 6.5 meters and DC/AC ratios of 1, 1.25, or 1.5. Two scenarios (7 and 8) use tilt angles of 26° and 18°, with a DC/AC ratio of 1.25. Scenarios 9 and 10 include a 26° tilt and azimuth angles of 165° and 150°, respectively. Key parameters, including power generation, performance ratio, specific production, shading losses, and clipping losses, are compared across all scenarios to identify the configurations with the highest and lowest performance outcomes. Obtained results show that higher DC/AC ratio increases power generation but also clipping losses and decreases PR and specific production. Lower tilt decreases both power generation and specific production, but PR is increased, and clipping losses are lower for lower tilt. It is interesting that for higher DC/AC ratio power generation difference is higher regarding interrow spacing (shading losses). Results presented here might help designers in development/design process but also academic as basis in research of presented area.
