© 2017 IEEE. Voltage control zones are commonly used within power systems, for applications like Secondary Voltage Control and localized reactive power markets. The idea is to partition a power system into zones that are weakly coupled in terms of voltage control. Conventionally, these control zones are defined with a deterministic approach and are fixed. However, recent research has demonstrated that they may be altered due to variation of the network structure and therefore suggested on-line reconfiguration of the zones. This paper goes a further step to probabilistically asses how the zoning could be affected by the uncertainties of operating condition (i.e., how the zones vary within a certain amount of time). Forced network outage, as the uncertain factor that affects the electrical distance between buses, is modeled in a realistic manner. Choropleth map is used to visualize the results. The 39-bus New England Test System (NETS) is used for demonstration.
