A bottom-up energy simulation framework to accurately compare PV module topologies under non-uniform and dynamic operating conditions

摘要: Non-uniform operating conditions of photovoltaic modules have a huge impact on the energy generation PV installations. To increase yield under non-uniform conditions, innovative module topologies been proposed. However, complete exploration these cannot be performed field, given cost/time investment required for realization all potential topologies, as well large time comprehensively testing them in real installation. Thus, it is more efficient and effective to compare through simulations. An accurate versatile simulation approach proposed here which allows different realistic time- spatially-varying shading scenarios. The latter are created by matching measured weather data with simulated dynamic scenarios using software SketchUp. use physics-based bottom-up modeling evaluation generated each topology conditions. Simulation results presented that substantiate feasibility methodology. Four relevant compared, showing better performance reconfigurable when uniform not dominant.
