Unified Framework for the Analysis of the Effect of Control Strategies on On-Load Tap-Changer’s Automatic Voltage Controller

With the advent of new loads and generation on low voltage grid, fluctuation has increased, especially in active distribution grids with a high penetration distributed resources large deployment electric vehicles. The coordination different technologies emerged as best way for regulation, among others, smart inverters, open soft points or transformers on-load regulation capability. This paper proposes novel to model control strategies automatic controller On-Load Tap-Changer transformers. purpose is standardize simplify these are represented, order facilitate (i) their selection by Distribution System Operators, (ii) future integration other systems, (iii) increase ability anticipate behavior. proposal been validated using real data, obtaining an accuracy 99.15% tap changer positions. A unified framework also introduced, which allows proposed functional representation be combined behavior estimation. experimental validation carried out where more than 150 000 have simulated, finally determining one that fits objectives. Note Practitioners —Historically, tap-changing used high-voltage substations. However, vehicles energy resources, need implement this type solution low-voltage substations grown. characteristics requirements not same, example, given nature, unbalanced often regulated ensure quality supply. Therefore, inheriting traditional changers may pose serious risk. facilitates modeling simulation almost any strategy changers. will allow choice parameters minimize deviation from setpoint maximize device lifetime. Our can considered uncertainty use. It performed before commissioning, based historical posteriori, collected data.
