Expandable quantum deep width learning-based distributed voltage control for smart grids with high penetration of distributed energy resources

Linfei Yin et al.

Summary: This paper presents a real-time distributed voltage control method to mitigate the risk of voltage violations caused by distributed energy resources in smart grids, and proposes an expandable quantum deep width learning algorithm to match this method. The effectiveness and expandability of the proposed algorithm and method are demonstrated through experiments on complex systems.

Monitoring Data Factorization of High Renewable Energy Penetrated Grids for Probabilistic Static Voltage Stability Assessment

Haosen Yang et al.

Summary: The increasing integration of renewable energy sources in power grids has created uncertainties that challenge traditional deterministic approaches for voltage stability assessment. This paper proposes a high-dimensional spatial-temporal matrix factorization approach to separate the deterministic part and uncertain elements caused by renewable energy sources, and presents a probabilistic index for online evaluation of voltage stability. The proposed method uses an adaptive and analytical model to describe the eigenvalue distribution of random components, and has been proven effective in various scenarios.

An interval power flow for unbalanced distribution systems based on the Three-Phase Current Method

Heitor M. Rodrigues Junior et al.

Summary: This paper proposes a novel methodology to determine interval results for power system load flow in three-phase unbalanced distribution networks. The proposed approach incorporates interval arithmetic and the Krawczyk operator to provide reliable interval three-phase results. The effectiveness of the method is demonstrated through computational simulations and its advantages over other methods are proven.

High-economic PV power compensation algorithm to mitigate voltage rise with minimal curtailment

Zhanqiang Zhang et al.

Summary: In this paper, a coordinated power compensation algorithm (PCA) is proposed to regulate bus voltage effectively with minimal power curtailment by selecting primary control nodes and optimal PV compensation orders based on sensitivity sequence. This method reduces the total power curtailment while serving requisite load demand, as verified by final results on a tested PV system model.
