Observability-Enhanced PMU Placement Considering Conventional Measurements and Contingencies
Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conve...
متن کاملEnhancing Observability in Distribution Grids using Smart Meter Data
Due to limited metering infrastructure, distribution grids are currently challenged by observability issues. On the other hand, smart meter data, including local voltage magnitudes and power injections, are communicated to the utility operator from grid buses with renewable generation and demand-response programs. This work employs grid data from metered buses towards inferring the underlying g...
متن کاملOptimal Self-healing of Smart Distribution Grids Based on Spanning Trees to Improve System Reliability
In this paper, a self-healing approach for smart distribution network is presented based on Graph theory and cut sets. In the proposed Graph theory based approach, the upstream grid and all the existing microgrids are modeled as a common node after fault occurrence. Thereafter, the maneuvering lines which are in the cut sets are selected as the recovery path for alternatives networks by making ...
متن کاملEfficient, Reliable and Fault-Diagnosable Authentication Scheme for Smart Grids
Authentication is a crucial requirement for smart grid communications. However, the current authentication approaches in the smart grid relying on per-packet signature and per-signature verification schemes introduce heavy costs for computation and communication. Furthermore, despite being much desired by the electric power industry, there are still no efficient fault diagnosis tools to support...
