Analyzing Cross-Phase Effects of Reactive Power Intervention on Distribution Voltage Control

no code implementations24 Nov 2023 Dhaval Dalal, Anamitra Pal, Raja Ayyanar

Increasing photovoltaic (PV) penetration in the distribution system can often lead to voltage violations.

Improving Photovoltaic Hosting Capacity of Distribution Networks with Coordinated Inverter Control -- A Case Study of the EPRI J1 Feeder

no code implementations5 Nov 2023 Dhaval Dalal, Madhura Sondharangalla, Raja Ayyanar, Anamitra Pal

Adding photovoltaic (PV) systems in distribution networks, while desirable for reducing the carbon footprint, can lead to voltage violations under high solar-low load conditions.

A SOCP-based ACOPF for Operational Scheduling of Three-phase Unbalanced Distribution Systems and Coordination of PV Smart Inverters

no code implementations12 Sep 2022 Mingyue He, Zahra Soltani, Mohammad Ghaljehei, Masoud Esmaili, Shanshan Ma, Mengxi Chen, Mojdeh Khorsand, Raja Ayyanar, Vijay Vittal

The results illustrate the effective-ness of the proposed ACOPF for unbalanced systems in provid-ing a global optimal solution while capturing the non-linearity and non-convexity of ACOPF.
