This paper presents an approach to determine the optimal PMU locations in order to render the complete observability to given power system using BPSO. Quadratic programming approach is used in BPSO, and results so obtained are compared with GAMS-MIP solver. A Method for Pseudo observability is also proposed for depth-one and depth-two with and without Zero injection measurements for IEEE-7, IEE...

Introduction The 1st Regional pain medicine symposia were held between the 14th and 18th of November 2011 in 3 cities (Nairobi, Mombasa and Dar-es-salaam), across 2 countries, Kenya and Tanzania. It was funded by the International Association for the Study of Pain (IASP), through the IASP developing country education grant for 2011 and The Aga Khan University Hospital Nairobi (AKUHN). It was or...

In this paper the state estimator is developed for the multi area power system with SCADA and PMU measurements using WLS method. The measurement jacobian matrix has been modified for the PMU measurements. The behavior of the elements because of the current measurements in the measurement jacobian matrix is examined for any possible ill-conditioning of the state estimator gain matrix. State esti...

Dynamic State Estimation (DSE) techniques have the ability to foresee potential contingencies and security risks. Any improvement in its ability to estimate would definitely go a long way in reducing the security risks in the modern power system. One important factor affecting the quality of estimation is the measurement accuracy. Phasor Measurement Unit (PMU) has revolutionized the way state e...

PURPOSE The purpose of this study was to compare the histologic features and cytokine profiles of experimental autoimmune uveitis (EAU) and a primed mycobacterial uveitis (PMU) model in rats. METHODS In Lewis rats, EAU was induced by immunization with interphotoreceptor binding protein peptide, and PMU was induced by immunization with a killed mycobacterial extract followed by intravitreal in...

The increasing penetration of Distributed Energy Resources (DERs) at the low andmediumvoltage levels is determining major changes in the operational procedures of distribution networks (DNs) that are evolving from passive to active power grids. Such evolution is causing non-negligible problems to DN operators (DNOs) and calls for advanced monitoring infrastructures composed by distributed sensi...
