4. 2. Synchrophasor Applications and their Vulnerability to Time Synchronization Impairment

   Author : Muhammad Shoaib Almas; Luigi Vanfretti; Mario Paolone; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hardware-in-the-loop; phasor measurement units; real-time simulation; time synchronization; wide-area monitoring protection and control.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. READ MORE

5. 3. Aspects of Wide-Area Damping Control Design using Dominant Path Synchrophasor Signals

   Author : Yuwa Chompoobutrgool; Luigi Vanfretti; Glauco Nery Taranto; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power system stability and control; inter-area oscillations; wide-area damping control; synchrophasor measurements; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The presence of inter-area oscillations has long affected stability constraints, and therefore, limited the power transfer capacity of interconnected power systems. Adequate damping of these inter-area oscillations is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. READ MORE

6. 4. Concepts for Power System Small Signal Stability Analysis and Feedback Control Design Considering Synchrophasor Measurements

   Author : Yuwa Chompoobutrgool; Luigi Vanfretti; Mats Larsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wide-area damping control; inter-area oscillations; power system stabilizers; PMU; Järnvägsgruppen - Elsystem; Järnvägsgruppen - Elsystem;

   Abstract : In the Nordic power network, the existence of poorly damped low-frequency inter-area oscillations (LFIOs) has long affected stability constraints, and thereby, limited power transfer capacity. Adequate damping of inter-area modes is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. READ MORE

7. 5. Data Quality in Wide-Area Monitoring and Control Systems : PMU Data Latency, Completness, and Design of Wide-Area Damping Systems

   Author : Kun Zhu; Lars Nordström; Boming Zhang; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phasor Measurement Units; Wide-Area Monitoring and Control systems; latency; completeness; power system communication; simulation; empirical study;

   Abstract : The strain on modern electrical power system operation has led to an ever increasing utilization of new Information Communication Technology (ICT) systems to enhance the reliability and efficiency of grid operation. Among these proposals, Phasor Measurement Unit (PMU)-based Wide-Area Monitoring and Control (WAMC) systems have been recognized as one of the enablers of “Smart Grid”, particularly at the transmission level, due to their capability to improve the real-time situational awareness of the grid.
