- Test system: Modified IEEE 37-node feeder with high photovoltaic penetration.
- Control scheme: Primal-dual VPP dispatch that simultaneously targets feeder-head active power tracking and voltage regulation.
- Network modeling: Communication effects are introduced only on the downlink path carrying dual-variable updates, modeling per-DER packet delays with a hold-last-value policy.
- Ideal communication results: Tight tracking of the feeder-head power reference, with voltages at selected buses kept within specified limits.
- Realistic downlink delays: The same controller exhibits large oscillations in feeder-head active power and more frequent voltage-limit violations.
Summary
Distribution networks with a high penetration of Distributed Energy Resources (DERs) increasingly depend on communication networks to coordinate grid-interactive control. However, most distributed control schemes are evaluated under idealized communication assumptions, making it hard to assess real-world performance.
This work provides an implementation-driven evaluation of a representative virtual power plant (VPP) dispatch algorithm using a co-simulation framework that couples a linearized distribution-system model with packet-level downlink emulation in ns-3.
Key points
Conclusion
Distributed DER control performance can be strongly influenced by communication behavior. The authors argue that evaluation frameworks should explicitly incorporate network dynamics when assessing grid-interactive control schemes.
