This paper presents one comprehensive modelling approach for maintenance scheduling problem of thermal power units in competitive market. This problem is formulated as a 0/1 mixedinteger linear programming model. Model incorporates long-term bilateral contracts with defined profiles of power and price, and weekly forecasted market prices for market auction. The effectiveness of the proposed mod...

Speed and vibration performance as well as obstacle avoidance performance of the previously proposed Electric Wheel Chair: EWC controlled by human eyes only is conducted. Experimental results show acceptable performances of speed vibration performance as well as obstacle avoidance performance for disabled persons. More importantly, disabled persons are satisfied with the proposed EWC because it...

—— This paper describes the preliminary research and implementation of an experimental test bench set up for an electric vehicle Antilock Braking System (ABS)/Traction Control System (TCS) representing the dry, wet and icy road surfaces. A Fuzzy logic based controller to control the wheel slip for electric vehicle antilock braking system is presented. The test facility comprised of an induction...

This paper describes a multi-agent based simulation (MABS) framework to construct an artificial electric power market populated with learning agents. The artificial market, named TEMMAS (The Electricity Market Multi-Agent Simulator), explores the integration of two design constructs: i) the specification of the environmental physical market properties, and ii) the specification of the decision-...

This paper presents a hybrid electric scooter model developed and simulated using Matlab/Simulink. This hybrid scooter modeled has a parallel hybrid structure. The main propulsion units consist of a two stroke internal combustion engine and a hub motor attached to the front wheel of the scooter. The methodology used to optimize the energy and fuel consumption of the hybrid electric scooter is t...

In this paper a three dimensional thermal model of a sliding contact system is proposed for both steady-state or transient conditions. The influence of contact force, electric current and ambient temperature on the temperature distribution, has been investigated. A thermal analysis of the different type of the graphite material of fixed electric contact and its influence on contact system tempe...

Ultrasonic shot peening (USP) studied. Several parameters (arc heights, surface roughness topography and micro hardness) with different parameters were measured. The research proposes curvature of shot peened sheet increases with time decreasing, while increases with pin diameter increasing, and curvature reaches a saturation level after a specific electric current. An empirical model of the re...

In this paper we present a model predictive control algorithm for scheduling electric vehicle charging. The model accounts for distribution network constraints and seeks to minimize the cost of procuring energy from the real-time market for electric vehicle charging. We present a case study for an IEEE test case distribution system.

Transformation of the monopolistic electric industry into a competitive and free market system is underscored by the wide price variation of electricity. To address price variation, the Federal Energy Regulatory Commission has proposed the development of fair competition in the wholesale power market as a first step toward full deregulation of the industry. This paper will discuss the steps tha...

Applying strong electric field on piezoelectric actuators, on one hand very significant electroelastic material nonlinear effects will occur, on the other hand piezo plates and shells may undergo large displacements and rotations. In order to give a precise prediction of piezolaminated smart structures under large electric field, this paper develops a finite element (FE) model accounting for bo...
