In this paper an optimal energy management strategy (EMS) for a light rail vehicle with an onboard energy storage system combining battery (BT) and supercapacitor (SC) is presented. The optimal targets for the proposed EMS are obtained by an optimization process with multi-objective genetic algorithms (GA). The fitness functions are expressed in economic terms, and correspond to the costs related...
SCADA (supervisory control and data acquisition) is a sophisticated system that allows controlling devices via coded signals into communication channels. Its main function is to allow the control of remote power system devices from a remote control center. In addition to the SCADA, complex software is required in order to analyze the data obtained from the system. Without proper analysis, the operator...
Unlike conventional hybrid electric vehicles (HEVs), the novel powertrain configuration of the University of Technology, Sydney (UTS) plug-in HEV (PHEV) contains only one electric machine, which functions as either an electric motor or a generator in different time intervals specified by a special energy management strategy (EMS). This paper presents a comparative analysis of the fuel economy and...
This paper is about simulation design of an Electronic Control Unit (ECU) for an adaptive cruise control (ACC) and for an engine management system (EMS). The simulation model allows processing of various sensors data like engine speed, engine temperature, and distance from the front vehicle. By collecting data from various sensors, ECU controls the vehicle speed by using electronic fuel injector actuator...
It is frequently hypothesized that environment management systems (EMS) may improve firms' innovation performance. Whether this hypothesis is true based on the relevant policy incentives for income distribution and its environmental innovation. There are two channels which EMS affects technical innovation (1) rich people migrate out region cause lower demand for local environment, (2) small size of...
Automatic generation control (AGC) is an important function for frequency control which is being implemented in the EMS system for the stable operation of power systems. The key feature of AGC is to back up governors for the control of system frequency of multi-machine systems. The governor has a role to regulate system frequency in several to ten seconds. But, the droop control concept which is applied...
To realize systematic analysis for electromagnetic susceptibility (EMS), forecast for electromagnetic compatibility (EMC), a modeling method on electromagnetic interference coupling path of digital relay in power system was presented. The simulated model of electromagnetic interference coupling path can be gotten by this method through the system identifying according to the experiment data. A mathematical...
