| The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways of dealing with voltage drop is the use of power electronics devices in sensitive feeders of distribution networks. In this research, dynamic voltage restorer is used. In order to avoid this voltage drop, optimal PID, fuzzy and fuzzy controllers are the controllers that this article intends to implement and compare their results. |
