Electric power network is a fundamental facility in modern society. The importance to ensure and enhance the security of the power network can never be over emphasized. In this paper, we study how the topology of a power network restricts the security. By focusing on the power balanced condition which is necessary for the security after line outage contingencies, we show that a practical power ...

We study the interaction between a fleet of electric, self-driving vehicles servicing on-demand transportation requests (referred to as Autonomous Mobility-on-Demand, or AMoD, system) and the electric power network. We propose a joint linear model that captures the coupling between the two systems stemming from the vehicles’ charging requirements. The model subsumes existing network flow models...

Optimization of specific power of axial flux permanent magnet brushless DC (PMBLDC) motor based on genetic algorithm optimization technique for an electric vehicle application is presented. Double rotor sandwiched stator topology of axial flux permanent magnet brushless DC motor is selected considering its best suitability in electric vehicle applications. Rating of electric motor is determined...

All rights Reserved. 11 Abstract— Ground level electric and magnetic-fields from overhead power transmission lines are of increasingly important considerations in several research areas due to their impact on health and environmental issues. The paper presents a more generalized technique to calculate the magnetic-field generated by power transmission lines...

Electric Power Transmission: Rationing a Limited Resource In the redesigned electric power industry, electricity-generating companies compete for customers and then transmit their electricity rarely be realized. Money collected by the central coordinator can be used to maintain and upgrade the transmission system. The researchers have already developed software that can produce using the existi...

Cascading failures are one of the main reasons for large scale blackouts in power transmission grids. Secure electrical power supply requires, together with careful operation, a robust design of the electrical power grid topology. Currently, the impact of the topology on grid robustness is mainly assessed by purely topological approaches, that fail to capture the essence of electric power flow....

Cascading failures in large-scale electric power transmission systems are an important cause of blackouts. Analysis of North American blackout data has revealed power law (algebraic) tails in the blackout size probability distribution which suggests a dynamical origin. With this observation as motivation, we examine cascading failure in a simplified transmission system model as load power deman...

In Part I of this work, analysis of uniform multi-conductor transmission line networks is performed on travelling-wave basis, via “quasi-TEM” approach. Narrowband interpretation of the modal theory in the time domain and quantification of the multiple reflections effect are both included. Theoretical demonstration and analytical formulation are provided, along with guidelines towards computatio...

Transmission constraints in electric networks can limit competition and create pockets of local market power. The policy response to this reality includes many elements ranging from special contracting arrangements to divestiture of assets. Although a full analysis of the impacts of local market power is complex and context specific, there are some general principles that can guide the discussion.
