The objective of this work is the optimization of a controlled electric vehicle (EV) strategy under a centralized architecture, considering a medium voltage electrical network. The method developed consists of a Particle Swarm Optimization, which determines the time available to charger each EV, segmentation of nodes of the network and their respective charging times, considering as constraints the...
Although batteries have been used in personal vehicles for more than a hundred years, the cost of the technology, limitation in range, absence of sufficient recharging infrastructure and rapid development of internal combustion engines during the mid-twentieth century limited its use to very niche applications. More recently, a global need for reducing CO2 emissions from fossil fuel usage and the...
Presented herein is Uniform Input Voltage Distribution (UIVD) control [6–9] for Distributed-Input Series-Output (DISO) converter power systems. UIVD for DISO converters is implemented to primarily achieve grouped maximum power throughput from non-identical power sources. This paper also offers a revised Maximum Power Tracking (MPT) controller [11] that facilitates simultaneous processing of distributed...
This paper presents a multiagent system (MAS) for real-time operation of a microgrid. The proposed operational strategy is mainly focused on generation scheduling and demand side management. In generation scheduling, schedule coordinator agent executes a two-stage scheduling: day-ahead and real-time scheduling. The day-ahead scheduling finds out hourly power settings of distributed energy resources...
Global Positioning Systems, thermal imaging scopes, satellite phones, and other electronic devices are critical to the warfighter in Forward Operating Environments. Many are battery operated and require charging. We used a Systems Engineering approach to compare existing portable energy systems and to specifically design a portable solar energy system for use tailored for a deployed military/combat...
Presented herein are three possible maximum power tracking approaches of harvesting energy from series-connected power sources: (1) commonly drawing the same current without active control for uniform voltage distribution among the output voltages of individual power sources, (2) partially across all individual power sources while being series-connected with uniform voltage distribution (UVD) control...
This paper presents a power system architecture where series-input parallel-output (SIPO) converters are controlled to achieve uniform input voltages across their respective series-connected power sources while also tracking the system optimum power point; the system optimum power point is the maximum power drawn from the series-connected power sources while their voltages are kept uniformly distributed...
This paper presents a scalable Multi-Agent System (MAS) for optimal operation of an islanded microgrid. Each autonomous element in the microgrid is represented as an intelligent agent in MAS. The MAS is developed such that it maximizes the power production of local distributed generators and minimizes the operational cost of microgrid subject to system constraints and units constraints. Agents in...
This paper reviews the forces and trends that have an impact on the evolution of exchange telecommunication networks and the effect each of these may have on central-office power systems. Alternative powering architectures are discussed, with considerations highlighted for each. No prediction is made as to which of the power architectures will dominate; this will depend on the evolution of various...
