Optimal PMU Placement for Power System Dynamic State Estimation by Using Empirical Observability Gramian [PDF]
, 2014 In this paper the empirical observability Gramian calculated around the operating region of a power system is used to quantify the degree of observability of the system states under specific phasor measurement unit (PMU) placement.

Research on the method of optimal PMU placement
International Journal of Online and Biomedical Engineering (iJOE), 2013 Taking the full network observability of power system and the least number of PMU as objective, to appearing fault situation in the grid, this paper proposes Differential Evolution and Particle Swarm Optimization (DEPSO) algorithm in view of the system failure rate. The improved DEPSO algorithm is global optimization,

Strategic PMU placement to alleviate power system vulnerability against cyber attacks
Energy Conversion and Economics, 2021 A strategic phasor measurement unit (PMU) placement scheme is proposed in this work to reduce the cyber vulnerability of the power system against cyber attacks. A multi‐stage PMU placement strategy is developed to alleviate the power system vulnerability

Efficient Convex optimization for Optimal PMU Placement in Large Distribution Grids [PDF]
2019 IEEE Milan PowerTech, 2019 The small amount of measurements in distribution grids makes their monitoring more difficult. Topological observability may not be possible, and thus, pseudo-measurements are needed to perform state estimation, which is required to control elements such as distributed generation or transformers at distribution grids.

Optimal Micro-PMU Placement Using Mutual Information Theory in Distribution Networks
Energies, 2018 Micro-phasor measurement unit (μPMU) is under fast development and becoming more and more important for application in future distribution networks. It is unrealistic and unaffordable to place all buses with μPMUs because of the high costs, leading

Low-Resolution Fault Localization Using Phasor Measurement Units with Community Detection [PDF]
, 2018 A significant portion of the literature on fault localization assumes (more or less explicitly) that there are sufficient reliable measurements to guarantee that the system is observable. While several heuristics exist to break the observability barrier,
