Summary: In this paper, a novel physics-aware harmonic state estimation (HSE) method is proposed for power distribution systems with low-observability. The method utilizes harmonic synchrophasors from Harmonic Phasor Measurement Units (H-PMUs) as the only available measurements. It addresses the challenging scenario of unknown harmonic sources and low observability by capturing the physics-based sparsity pattern and formulating it as a mixed-integer quadratic programming optimization.

Summary: This article proposes a measurement-based approach for locating the sources of forced or poorly damped oscillations in a power system. The approach utilizes cross-power spectral density to calculate the correlation between synchronized voltage and power signals, and compares the spectral densities to determine the type of oscillation source. Preprocessing of signals using variational mode decomposition allows for extraction of the dynamic component. The proposed approach has successfully identified test cases in the IEEE-NASPI Oscillation Source Location Contest and demonstrates advantages over the state-of-the-art dissipating energy flow method.

Summary: Transmission line fault location is crucial for power system restoration after outages, with existing methods mainly relying on fundamental phasors. Traditional fault locators typically use phasor estimations from protective relays or P-class Phasor Measurement Units, but there is limited research on using M-class data for fault location. This study found that M-class phasor measurements can be effectively used in fault location applications, yielding errors within expected levels for phasor-based methods.

Summary: This paper presents a new formulation for intentional controlled islanding (ICI) of power transmission grids based on mixed-integer linear programming (MILP) DC optimal power flow (OPF) model. It proposes several improvements to address deficiencies in the existing formulation, such as a new optimization objective, island connectivity constraints, constraints for DC OPF with switching, and a heuristic to find initial feasible solutions. The proposed improvements reduce the optimality gaps compared to the benchmark model on multiple test instances.

Summary: A new control scheme is proposed to overcome the issue of lower sensitivity or misoperation of fault component-based directional elements in converter-interfaced renewable energy sources (CIRESs). This scheme adjusts the sequence impedance angles by computing suitable current references of the CIRES controller and maximizing them using an iterative algorithm. It is compatible with different fault types, power factors, weak grids, and larger fault resistances. The proposed scheme satisfies the necessary fault ride-through (FRT) requirements without updating protection algorithms or revising controller parameters based on the detected fault type, using only local measured data. PSCAD simulations, RTDS testing, and hardware experiments validate the efficacy of this method.

Summary: With the increasing penetration of converter-interfaced generators, the frequency containment reserve (FCR) from conventional generators keeps going down, leading to a potential risk of frequency instability under contingencies. Consequently, Converter-interfaced generators are required to provide FCR and participate in the corrective rescheduling. A cross-entropy-based frequency-constrained contingency-state-analysis (FC-CSA) model is proposed in this paper to assess the FCR and quantify the adequacy of FCR under contingencies.

Summary: This study proposes an indirect model predictive control (MPC)-based zero-sequence current control method, which provides direct current fault suppression by continuously controlling the zero-sequence current component and providing feedback to the outer voltage loop and inner current loop of the modular multilevel converter (MMC).

Summary: With the increasing number of severe system disturbances and blackouts globally, controlled system separation is becoming an important system integrity protection scheme to prevent the electric power system from disintegration. This article proposes a novel PMU-based detector that utilizes generator PMU data to promptly detect rotor angle instabilities over a wide area, and demonstrates how it can be integrated with controlled splitting techniques to defend against unintentional loss of synchronism. The performance of this wide-area SIPS is demonstrated on the IEEE 39-bus test power system under various unstable conditions.
