Secondary voltage control using pilot point information
Control of the pilot point voltage in a given region involves only one measurement and one control decision making. Once the control is obtained for one generator, the others in the same region operate with the same portion of the maximum reactive power that they can produce. Note that this concept assumes that the voltage control is regional (not systemwide) and that it is therefore necessary to have a systemwide coordination of the reactive power flow between different regions. This control level is referred to in the French literature as the tertiary control, and it has not been automated yet. In this study the regional solution as practiced on the French system is just a particular case of the more general secondary control approach in which systemwide pilot points are found: not necessarily just one pilot point is associated with one region and all the generators work together to maintain the system-wide voltage profile. In this sense, no additional coordination is necessary. This is the same as in a previous study, in which it was shown that the French control concept is only one version of a possibly more general concept of the reduced voltage information structure for monitoring and control.
