What is Long-Duration Voltage Variation Analysis about?

This document discusses three cases analyzing long-duration voltage variations along a distribution feeder supplying two cities and a factory. In Case 1, the voltage profile is analyzed without corrections and the voltage is below acceptable levels at the last node. In Case 2, an on-load tap changing (LTC) transformer is added to regulate the voltage and corrects the undervoltage. However, voltages are too high when load is reduced to 20%. Case 3 proposes controlling the LTC based on voltage measurements at
