This paper presents a novel algorithm to optimize a topology for tackling the challenge of increasing uncertainty on load demand (growth rate with connection of new loads) in low-voltage (LV) distribution. This paper aims at finding which load connection phase induces the lowest costs (investment and power losses) and phase balancing while satisfying the techno-economic aspects over planning study...
Partial shading of photovoltaic (PV) modules can affect a wide variety of plants ranging from utility-sized solar trackers to residential building-integrated PV, resulting in lower energy production yields. The traditional series-parallel interconnection scheme of solar arrays is sensitive to disparate solar irradiation levels on modules of the plant. By using alternative topologies, the effects of...
Several grid connected photovoltaic system topologies are used in existing installations. This paper proposes evaluation criteria for comparing and choosing topologies compatible with the user's demands. After presenting an overview of current architectures used in grid connected systems, five key points for comparison based on topology upgradeability, performance under shaded conditions, degraded...
This paper deals with distribution network (DN) reconfiguration for loss minimization. To solve this combinatorial problem, a genetic algorithm (GA) is considered. In order to enhance its ability to explore the solution space, efficient genetic operators are developed. After a survey of the existing DN topology description methods, a theoretical approach based on the graph and matroid theories (graphic...
