TSO-DSO Coordinated Reactive Power Dispatch for Smart Inverters with Multiple Control Modes Real-Time Implementation

Mohammad Almomani, Ahmed Alkhonain, Venkataramana Ajjarapu

This paper presents TSO-DSO coordinated reactive power dispatch, with a focus on real-time implementation. A sensitivity-aware, mixed-integer linear programming (MILP) formulation is developed to model the IEEE 1547-compliant droop-based control modes Volt VAR (VV), Volt Watt (VW), and Watt VAR (WV) of …

Sensitivity-Aware Reactive Power Dispatch of DERs to Support Transmission Grid During Emergency

Ahmed Alkhonain, Ankit Kumar Singhal, Alok Kumar Bharati, Venkataramana Ajjarapu

This paper proposes a TSO-DSO framework including DER set-point dispatch using sensitivity analysis. We address all three steps of TSO-DSO integration stating by estimating the capability curve of an unbalanced distribution system and then modeling of capability curve on the transmission side …
