This paper presents a distributed multi-agent scheme for enhancing the cyber security of smart grids which integrates computational resources, physical processes, and communication capabilities. Smart grid infrastructures are vulnerable to various cyber attacks and noises whose influences are significant for reliable and secure operations. A distributed agent-based framework is developed to investigate...
In this paper, a distributed multi-agent scheme is presented for reactive power management with renewable energy sources (RESs). The multi-agent system (MAS) framework is developed for distribution systems to improve the stability which is mostly dominated by voltage and the agents in this framework coordinate among themselves using online information and energy flow. In this paper, the agents basically...
This paper presents the dynamics of photovoltaic (PV) cell with Plug in Hybrid Electric Vehicles (PHEVs) load. It is expected that PHEVs are going to be charged during the day with solar PV energy sources at the parking sites of PHEVs. The present work offers a complete system for charging PHEVs with PV cell where PHEVs load are modelled based on third order battery model. System dynamics are analyzed...
Flywheel energy storage (FES) has attracted new interest for uninterruptable power supply (UPS) applications in a facility microgrid. Due to technological advancements, the FES has become a promising alternative to traditional battery storage technologies. This paper aims at developing a tool to demonstrate the use of FES units for securing critical loads during a utility outage in a microgrid environment...
This paper presents an efficient O(n3) time algorithm for solving the seeded tree alignment problem that finds the similarity score of two RNA secondary structures. In the seeded tree alignment problem, a large tree, representing an RNA secondary structure, is converted into a small tree known as seeded tree. After conversion, a comparison operation is being placed to find the similarity score of...
Field Oriented Control (FOC) Permanent Magnet Synchronous Motor (PMSM) is a commutator less servo drive which provides high controllability, greater efficiency, superior torque to inertia ratio and high power density. However, the performance of FOC-PMSM depends on the driver circuits, which requires expensive computing elements. Besides, an intelligent current regulator is desired for a highly precise...
As Plug-in Hybrid Vehicles (PHEVs) take a greater share in the personal automobile market, their penetration levels may bring potential challenges to electric utility especially at the distribution level. This paper examines the impact of charging PHEVs on a distribution transformer under different charging scenarios. The simulation results indicate that at the PHEV penetration level of interest,...
