Technical and analytical report focused on the analysis of On-Load Tap Changer (OLTC) operations in power transformers within a distribution network, particularly in the context of the increasing integration of renewable energy sources. The report likely addresses the challenges posed by the variability and intermittency of renewable energy, such as solar and wind, and how these factors influence the frequency of OLTC operations, which are critical for maintaining voltage stability in the grid. The document includes a detailed statistical analysis of data from various substations, examining the correlations between OLTC activity and different variables, including voltage levels, power fluctuations
