system outages. Voltage collapse occurs when the electric system tries to serve more load than the voltage can support. Voltage control can be properly maintained by the gener-ation or consumption of reactive power. Generation of reactive power will increase the system voltage while consumption of reactive power will decrease the system voltage.
