Reactive power control in power system
WebIn the case that the reactive power has to be controlled, a reactive power reference must be imposed to the system. Linear PI controller is an established reference tracking technique associated with the d-q control structure due their satisfactory combinational performance. Eq. (8) states the transfer function on the d-q coordinate structure. Webpower. Generation of reactive power will increase the system voltage while consumption of reactive power will decrease the system voltage. Without adequate supply of reactive power, the electrical system cannot reliably deliver real power. Voltage control in distribution systems is typically performed at the distribution substation level.
