Robotics sector have achieved enormous founds in recent years due to its high demands in factories to carry out high-precision jobs like riveting and welding. They are also often applied in special situations that would be hazardous for humans such as disposing toxic wastes or defusing bombs. Mobile robots alone however have gained much focus from researches relating optimization of their motion path...
Rapid development of information and communications technology changed our world for the better in the last couple of years. It has also opened the door ahead of new possibilities in order to organize large social systems like urban transportation more efficiently. However, exploitation of these opportunities in this smarter world is still at a low level. A major reason for this could be that smarter...
The Mines and Energy Planning Unit (UPME) is responsible for establishing the energy requirements of the population according to economic, social, technical and environmental principles. UPME updates the official document entitled “Power Generation and Transmission System Expansion Plan” every year. The power generation requirements, which are proposed by the Unit, are indicatives, because most of...
Planning of protection systems has been a significant task in order to achieve an efficient behavior of distribution systems. Feeders that offer high robustness and reliability are essential to ensure continuous energy delivering to all customer loads. Since distributed generation (DG) has increased its penetration in distribution systems, it has become necessary to place protective devices (such...
Large cities face growing mobility problems, due to the major traffic jams that result from high numbers of vehicles on the roads. In response, city and national governments have invested in alternative means of urban passenger transit, such as subways, trains, as well as Bus Rapid Transit (BRT). This article aims to analyze the BRT system, by attempting to calculate the probability of reaching a...
Communications through networks, at present, involves the transfer of information in different amounts and times for each type of service. In a telephone conversation a small loss of information can be tolerated, since in this case, is more important the rate with which the data reaches the receiver. When it is required to transfer sensitive information such as banking data, longer times of arrival...
In this paper, a robust methodology is proposed for planning multistage distribution networks. The scenario set is used to describe the uncertainty of DGs and loads in which the quantity and type are simultaneously considered. Furthermore, controllable load is considered apart from traditional load. Based on the constructed scenario, high-voltage/medium-voltage (HV/MV), feeder route, tie-line and...
The Distribution System is the physical interface between the utility and consumers. In order to ensure the reliability in the power supply, a good expansion and operation planning is required. Moreover, the planning of system is important to the optimization of the investments made by the utilities. In this sense, the diagnostic of the distribution system under study is essential to establish appropriate...
This paper describes the study methodology for network planning based on reconfiguration transmission network to Facilitate operate the network in reliable, secure and efficient way. All operating areas within country grid are interconnected through transmission network which consider as a source feeding sub transmission network. The underlying sub transmission network, being electrically parallel...
Ongoing developments in the electricity system are changing the requirements for planning and design of distribution networks. Based on field research at several Dutch distribution network operators a conceptual planning process is defined and current practices in distribution network planning in the Netherlands are investigated. Currently mainly traditional deterministic approaches are applied, but...
This paper presents a literature study on asset management in electrical power transmission and distribution system. Due to restructure and deregulation of electric power industry in recent times, the focus has been on transmission and distribution assets that include transmission lines, transformers, power plants, substations and support structures. The study aims to provide a first of its kind exposure...
In order to maintain reliability and reduce uncertainties in the operation of the distribution network caused by a large penetration of distributed generation and energy intensive appliances, monitoring capabilities of distribution networks need to be improved for the deployment of proper control actions. This paper proposes a conceptual framework for securing network operation by enhanced monitoring...
Human-induced faults play a large role in systems reliability. In cloud platforms, system administrators may inadvertently make catastrophic mistakes, like deleting a virtual disk with important data. Providing rollback for cloud operations can reduce the severity and impact of such mistakes by allowing to revert back to a known, good state. In this paper, we present a scalable approach to rollback...
Underperformance of industrial DSM projects is often caused by a lack of proper maintenance practices. This results in wasted electricity cost-savings opportunities and an increased demand for electricity on the national grid. A solution to the problem of underperforming industrial DSM projects is to apply a performance-centered maintenance (PCM) strategy. The various aspects of the PCM strategy are...
Businesses today need to be more effective and efficient in order to design the best products and provide outstanding services to their customers. The purpose of this research is to develop and improve quality efficiency while sustaining continuous improvement at a South African Energy provider's Mpumalanga plant, which is one of the nine regions in South Africa.
Agile Software Development (ASD) has been on mainstream through methodologies such as XP and Scrum enabling them to be applied in the development of complex and reliable software systems. This paper is the end result of the Master's dissertation of the main author, and proposes a solution to guide the development of complex systems based on components by adding exceptional behavior modeling practices...
Reliability is one of the most concerned issues in wireless communications for smart grid, especially in the home area network(HAN) where the smart meter data are collected. In this paper, we model the HAN as a wireless mesh network that deploys cooperative transmissions for improving link reliability. We then define a new reliability performance metric that depends not only on the channel model but...
The purpose of this study is to investigate the impact of market uncertainty on e-connection and process coordination with suppliers and the operational performance. A Structure Equation Model containing two intermediary variables is established. Through an empirical survey of 725 samples in an international study, the research findings show that: (1) market uncertainty has a negative impact on operational...
The integration of increasing amounts of intermittent renewable generation whose reliability contributions are significantly different than those of the historically dispatchable thermal generating units is important to future electric generation planning. With relatively small amounts of intermittent generation, reliability impacts may not be detectable; however, as renewable integration goals continue...
This paper examines the extent of resource adequacy and the North American Bulk Power System's resilience to extreme weather events. Observations and lessons learned from the 2014 polar vortex event provide valuable insight to NERC's assessment of the upcoming and future winter seasons. In order to gain a better understanding of how extreme weather events can impact reliability in future winter seasons,...
