Energy Science &Engineering, Volume 14, Issue 3, Page 1505-1528, March 2026.This study presents a hierarchical coordination framework where multiple VPPs interact with the DSO to optimize energy trades and flexibility offers. Each VPP aggregates DERs and DR, performing internal optimization, day‐ahead bidding, and assessing flexibility to reduce excess renewable generation and pollution.

High Voltage DC Active Current Injection to Simulate Geomagnetically Induced Currents in New Zealand
Space Weather, Volume 24, Issue 3, March 2026.Abstract This study investigates the effects of geomagnetically induced currents (GIC) on New Zealand's electrical infrastructure via an intentional ground injection of direct current (DC) from a high voltage DC converter station. GIC manifests as quasi‐DC currents within power systems, potentially causing transformer saturation, increased reactive ...
