Secure and reliable opertation of the grid requires real time monitoring and control of entire power system. Phasor measurement units (PMU) are being deployed for real time monitoring and analysis of power system. The most important factor to be considered in placement problem is observability of power system with minimum number of PMUs. This paper proposed an Integer Linear Programming (ILP) b...

The power system industry has been going through dynamic infrastructural and operational changes in recent years that have caused more prominent lightly damped electromechanical oscillations. Real-time monitoring of electromechanical oscillations is of great significance for power system operators; to this aim, software solutions (algorithms) that use synchrophasor measurements have been develo...

OBJECTIVE To evaluate technical efficiency and potential presence of scale and scope economies in Mexican private medical units (PMU) that will improve management decisions. MATERIALS AND METHODS We used data envelopment analysis methods with inputs and outputs for 2 105 Mexican PMU published in 2010 by the Instituto Nacional de Estadística y Geografía from the "Estadística de Unidades Médica...

Increased adoption and deployment of phasor measurement units (PMU) has provided valuable fine-grained data over the grid. Analysis over these data can provide real-time insight into the health of the grid, thereby improving control over operations. Realizing this data-driven control, however, requires validating, processing and storing massive amounts of PMU data. This paper describes a PMU da...

With the increasing penetration of converter-based renewable resources, different types dynamics have been introduced to power system. Due complexity and high order modern system, mathematical model-based inertia estimation method becomes more difficult. This paper proposes two novel machine learning assisted methods based on long-recurrent convolutional neural (LRCN) network graph (GCN) respec...

This research examines an admissible search algorithm-dependent A-star strategy and takes into account redundancy cost/benefit analysis under normal operating conditions. The goal is to allocate a phasor measurement unit (PMU) for maximal observability of the interconnected power network. To determine fewest number PMU required make connected network totally observable using analysis, approach ...
