As the transition to renewable energy sources progresses, the integration of such sources makes electricity production increasingly fluctuate. To contribute to power grid stability, electric utilities must balance volatile supply by shifting demand. This measure of demand response depends on flexibility, which arises as the integration of information systems in the power grid grows. The option ...

Advanced weapons and sensors increase demand on the electric power systems of Navy surface combatants, driving the need for fully Integrated Power Systems (IPS) such as those found in the DDG-1000 Zumwalt class of ships. The goal of this paper is to introduce novel power system configurations that could potentially be integrated into future flights of the DDG-51 class to support expanded electr...

As the Electric Distribution industry enters the Smart Grid era, it is deploying a variety of new technologies (including distributed energy resources) and communications infrastructure to enhance the performance of the distribution grid, improve customer satisfaction and reduce the carbon footprint. On the one hand, these new Smart Grid investments look as though they will pay off as customers...

In a world where environment protection and energy conservation are growing concerns, the development of electric vehicles (EV) and hybrid vehicles (HEV) has taken on an accelerated pace. Electricity is gaining more importance in critical applications such as transportation (with more electric aircrafts and electric vehicles) where continuity of operation is crucial and there is a growing deman...

Electric Vehicles (EVs) require energy storage system that can address its fast changing load requirements such as sudden acceleration or quick regenerative braking by being able to supply or absorb high power as demanded. Lead Acid Batteries, commonly used in cheaper EVs (like electric tempo in Nepal), can properly supply these variable loads and get recharged but this mode of operation drasti...

Microgrid (MG) is one of the important blocks in the future smart distribution systems. The scheduling pattern of MGs affects distribution system operation. Also, the optimal scheduling of MGs will be result in reliable and economical operation of distribution system. In this paper, an operational planning model of a MG which considers multiple demand response (DR) programs is proposed. In the ...

With the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

With the development of deregulated power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benefi...

Electric vehicles (EVs) and particularly plug-in hybrid electric vehicles (PHEVs) are foreseen to become popular in the near future. Not only are they much more environmentally friendly than conventional internal combustion engine (ICE) vehicles, their fuel can also be catered from diverse energy sources and resources. However, they add significant load on the power grid as they become widespre...

We consider the scheduling of flexible electric loads in a smart grid so as to minimize peak power demand. Specifically, we focus on the case when the loads are preemptable, their power requirement and duration are known in advance, and they have the same earliest start time and the same deadline. Our main results are (a) when power requests are scheduled preemptively, the peak power demand can...
