“…where Q + DER is the maximum reactive power that the DER can inject at the time of request, and 0 ≤ ρ ≤ 0.3 is used to regulate the responsiveness of the DER to avoid unnecessary overreactions [31]. After several coordinator requests, the DER may fully utilize its reactive power capacity; for details see [34]. For reactive power absorption, the setpoint changes by an amount…”

“…The literature has scarcely reported on long-term voltage stability enhancement with the resources installed at LV levels [34]. The use of small-scale DERs to support TNs in emergency situations poses additional challenges in terms of communication, coordination, availability, and response of hundreds or thousands of agents.…”

The large-scale integration of renewable generation and the gradual decommissioning of conventional power plants has led to decreased availability of resources for providing services and support to the bulk transmission grid. This paper presents a novel methodology for providing support to the bulk transmission system through the control of thousands of small distributed energy resources (DERs), located in distribution systems. This control scheme is expected to serve jointly with other classical countermeasures against instability conditions. The proposed method is model-free, scalable, and does not rely on extensive communication infrastructure. It integrates an online method (New LIVES) to monitor the voltage stability status of the transmission system, a rule-based decentralized decision algorithm, and the local DER mechanisms implementing the control actions. The proposed approach is implemented on a combined transmission and distribution test system with over 4200 low-voltage buses and the dynamic simulation results illustrate its flexibility, practicality, and tractability.
