What is an effect of connecting too much inductive load during system restoration?

Connecting too much inductive load during system restoration can significantly decrease voltage stability. Inductive loads, such as motors and transformers, consume reactive power (VARs) from the electrical system. When excessive inductive loads are connected, they draw more reactive power than is available, leading to a drop in system voltage levels. This can cause voltage stability issues, potentially resulting in voltage collapse or cascading failures if the system cannot maintain adequate voltage levels across the network.

Inadequate reactive power not only affects the ability of the system to maintain voltage but can also hinder the overall performance of the network as it attempts to restore stability. Importantly, this scenario highlights the need for careful management of power system loads during restoration processes to ensure that voltage levels remain within acceptable limits.
