The study started with the requirement that a photovoltaic (PV) power source should be integrated with other supplementary power sources whether it operates in a stand-alone or grid-connected mode. First, fuel cells for a backup of varying PV power were compared in detail with batteries and were found to have more operational benefits. Next, maximizing(More)
Reliability is a key aspect of power system design and planning. In this research we present a reliability analysis algorithm for large scale, radially operated (with respect to substation), reconfigurable, electrical distribution systems. The algorithm takes into account equipment power handling constraints and converges in a matter of seconds on systems(More)
— Stakeholders' expectations and technology constantly evolve during the lengthy development cycles of a large-scale computer based system. Consequently, the traditional approach of baselining requirements results in an unsatisfactory system because it is ill-equipped to accommodate such change. In contrast, systems constructed on the basis of Capabilities(More)
This paper presents a new method for studying the electromechanical transients in power systems using combined Transmission and Distribution (T&D) models. Unlike the traditional dynamics analysis techniques which assume a balanced electric network, the methodology presented in this paper models individual phases of the power system and associated imbalances(More)
This paper presents distributed algorithms for both radial and looped load flows for unbalanced, multi-phase power distribution systems. The distributed algorithms are developed from tree-based sequential algorithms. Formulas of scalability for the distributed algorithms are presented. It is shown that computation time dominates communication time in the(More)
When considering the operation of an Unmanned Aerial Vehicle (UAV) or an Unmanned Ground Vehicle (UGV), such problems as landing site estimation or robot path planning become a concern. Deciding if an area of terrain has a level enough slope and a wide enough area to land a Vertical Take Off and Landing (VTOL) UAV or if an area of terrain is traversable by(More)
(ABSTRACT) Transactional memory (TM) has emerged as a promising synchronization abstraction for multi-core architectures. Unlike traditional lock based approaches, TM shifts the burden of synchronization from the programmer to an underlying framework using hardware (HTM) and/or software (STM) components. Although STM provides a generic solution for(More)
