Three‐phase steady‐state models of distributed generators with different control strategies

IET Generation, Transmission &Distribution, Volume 18, Issue 4, Page 716-728, February 2024.
This paper proposes three‐phase steady‐state models for distributed generators with different negative control strategies. Abstract This paper proposes three‐phase steady‐state models for distributed generators (DGs) with different negative control strategies. An augmented rectangular load flow method is used for three‐phase distribution systems.

Research on OPF Control of Three‐Phase Four‐Wire Low‐Voltage Distribution Network considering Uncertainty

International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
As power systems become more complex and uncertain, low‐voltage distribution networks face numerous challenges, including three‐phase imbalances caused by asymmetrical loads and distributed energy resources. We propose a robust stochastic optimization (RSO)‐based optimal power flow (OPF) control method for three‐phase four‐wire low‐voltage distribution

Statistical evaluation of voltage unbalance in residential distribution networks with a high penetration level of small wind turbines

, 2013
Voltage unbalance (VU) in residential distribution networks (RDNs) is mainly caused by the load unbalance in three phases, resulting from network configuration and time variation of the loads.
