Abstract ：
Power system state estimation is a primary and major method for monitoring power grids in real time. Massive synchrophasor data contains temporal correlations and spatial characteristics based on the physical constraints of the power system. The spectral-domain convolution method based on the graph Fourier transform is used to construct a multilayer graph convolution neural network model to predict the short-term states of a power system, including the latest state, when the power system is in the quasi-steady state. Combining the advantages of linear state estimation, a forecasting-aided state estimation method that can take advantage of predicted values and phase measurement units is designed to obtain the real-time state. Furthermore, predicted innovations analysis method are proposed to identify system mutations and bad data. Enough simulation tests validate that the proposed method can accurately estimate the real-time state of a power system.

Abstract ：
The proliferation of distributed energy resources and the introduction of new loads in distribution networks present significant challenges for monitoring and operation. To satisfy the enhanced observability and controllability requirements of modern distribution networks, there is an increasing demand for advanced monitoring devices. Distribution Network Phasor Measurement Units (DPMUs) offer high-precision measurement data with precise timestamps, thereby improving both the accuracy and redundancy of measurements within the distribution network.This paper introduces an optimization model for the strategic placement of PMUs within distribution networks, leveraging node metric indices. The indices considered are node degree, spatiotemporal correlation, and node power ratio. The relative importance of these indices is determined using an improved entropy weight method, which quantifies the differentiation of nodes within the network. This method facilitates the prioritized placement of DPMUs at critical nodes. The proposed model also incorporates constraints such as the depth of unobservability and zero injection nodes. Utilizing a 0–1 integer programming algorithm, the model derives a multi-stage optimal placement scheme for PMU placement. This scheme evolves from incomplete observability to critical observability and ultimately to full redundancy. Importantly, this approach allows for the monitoring of key nodes within the distribution network and enhances measurement redundancy without necessitating an increase in the number of placements. © 2024 Elsevier Ltd

Abstract ：
Emergency control is essential for maintaining the stability of power systems, serving as a key defense mechanism against the destabilization and cascading failures triggered by faults. Under-voltage load shedding is a popular and effective approach for emergency control. However, with the increasing complexity and scale of power systems and the rise in uncertainty factors, traditional approaches struggle with computation speed, accuracy, and scalability issues. Deep reinforcement learning holds significant potential for the power system decision-making problems. However, existing deep reinforcement learning algorithms have limitations in effectively leveraging diverse operational features, which affects the reliability and efficiency of emergency control strategies. This paper presents an innovative approach for real-time emergency voltage control strategies for transient stability enhancement through the integration of edge-graph convolutional networks with reinforcement learning. This method transforms the traditional emergency control optimization problem into a sequential decision-making process. By utilizing the edge-graph convolutional neural network, it efficiently extracts critical information on the correlation between the power system operation status and node branch information, as well as the uncertainty factors involved. Moreover, the clipped double Q-learning, delayed policy update, and target policy smoothing are introduced to effectively solve the issues of overestimation and abnormal sensitivity to hyperparameters in the deep deterministic policy gradient algorithm. The effectiveness of the proposed method in emergency control decision-making is verified by the IEEE 39-bus system and the IEEE 118-bus system. © 2024 Elsevier Ltd

Abstract ：
For data-driven dynamic stability assessment (DSA) in modern power grids, DSA models generally have to be learned from scratch when faced with new grids, resulting in high offline computational costs. To tackle this undesirable yet often overlooked problem, this work develops a light-weight framework for DSA-oriented stability knowledge transfer from off-the-shelf test systems to practical power grids. A scale-free system feature learner is proposed to characterize system-wide features of various systems in a unified manner. Given a real-world power grid for DSA, selective stability knowledge transfer is intelligently carried out by comparing system similarities between it and the available test systems. Afterward, DSA model fine-tuning is performed to make the transferred knowledge adapt well to practical DSA contexts. Numerical test results on a realistic system, i.e., the provincial GD Power Grid in China, verify the effectiveness of the proposed framework.

Abstract ：
The current harmonic state estimation mostly uses the synchronous phasor measurement data, but due to the large data acquisition cost, it is difficult to meet the observability requirements of the harmonic state estimation. Relatively speaking, the power quality observer, which is less expensive and convenient for large-scale deployment, is easier to meet the observability requirements of the harmonic state estimation. However, this traditional deterministic harmonic state estimation is low in accuracy. Therefore, based on the asynchronous harmonic monitoring data, a robust dynamic harmonic state estimation is proposed in this paper. Firstly, an interval dynamic harmonic state estimation model considering the uncertainty of the harmonic state is constructed. The asynchronous harmonic monitoring data are processed by means of the phase angle synchronization to obtain the starting value of the model. Then, an extended interval Kalman filter algorithm is proposed combining the interval Taylor expansion and the upper bound optimization to reduce the conservation of the interval harmonic state. At the same time, a gain matrix adaptive adjustment based on the robust factor is used to eliminate the influence of the bad data on the accuracy of the state estimation. Finally, an example in the IEEE57 bus system is tested to verify the feasibility and effectiveness of the proposed method. © 2023 Power System Technology Press. All rights reserved.

Abstract ：
With the high access of renewable energy, complex and changeable transmission networks, and frequent load interactions, the dynamic characteristics of low-carbon power systems have become more complex and random. The 10 ms-level dynamic measurement data of Phasor Measurement Unit are the basis for dynamic awareness, control and decision. However, the phenomenon of low-quality data usually exists in PMU measurements. Considering the spatial-temporal correlation reflected by the random matrix single-ring theorem and correlation coefficients, two system operating states and two types of low-quality PMU data are determined. Based on singular value decomposition and reconstruction, the distribution of the residuals between the original data and reconstructed data is analyzed to realize low-quality PMU data identification. To improve the identification accuracy, a dynamic threshold selection method of spatial-temporal correlation analysis is proposed for iden-tification criteria. The feasibility and applicability of this method has been verified in the simulation data of IEEE 39 bus system and PMU measured data of the practical power grid.

Abstract ：
当前的谐波状态估计大多采用同步相量测量数据，但数据获取成本大，难以满足谐波状态估计的可观要求。相比较而言，电能质量监测装置成本更小、利于大范围布设，更容易满足谐波状态估计的可观要求，但谐波状态估计精度较低。因此，该文基于非同步谐波监测数据，提出鲁棒动态谐波状态估计方法。首先，构建考虑谐波状态不确定性的动态谐波状态估计模型，并通过相角同步化手段处理非同步的谐波监测数据，以获取模型求解的启动值；其次，提出结合区间泰勒展开和上界优化方法的扩展区间卡尔曼滤波算法，对动态谐波状态估计模型进行求解，降低所得区间谐波状态估计量的保守性；同时，采用基于鲁棒因子的增益矩阵自适应调整方法，剔除坏数据对状态估计准确性的影响；最后，在IEEE57节点系统算例验证该文方法的可行性与有效性。
