It's an exploratory review study, based on testing the hypothesis concerned. The statuesque is already in the existence in the form of the established theories and side of hypothesis need not to be researched again separately, considering it as the prior work referred. That was not a part of this study, this study is a further episode of the same series of research. Operations management was limited...
The Ocean Observatories Initiative (OOI) consists of seven research sites collecting ocean, seafloor, and meteorological data in the world's oceans, extending from the Irminger Sea to the Southern Ocean, and the East and West coasts of the United States. The Ocean Observatories Data Evaluation Team is part of the Cyberinfrastructure group at Rutgers University, tasked with reviewing the oceanographic...
A novel control strategy for battery energy storage system (BESS) which is integrated within photovoltaic power station is presented in this paper. Normally the function of BESS is to mitigate the power fluctuation of PV to meet the requirements of dispatch center. In this paper, besides PV fluctuation smoothing, peak power shaving is also considered in the control strategy of BESS, which means part...
The optimal operation system is the key instruction system in CCHP (combined cooling, heating and power) systems, while its development and test always keep a challenge due to the structure complexity and high energy coupling degree. To solve this problem, an emulation testing platform was designed for CCHP systems to test and verify the specified optimal operation system. The stability and reliability...
The article presents a typical construction of the roadway of the railway line on the Yamal Peninsula. Also presents are the provisions of an integrated method, taking into consideration geo-extreme conditions of the Russian Arctic Zone, containing the solutions aimed at operational reliability improvement of the railway line.
The interconnection between DC microgrids has been studied through the modeling and simulation of two DC microgrids and utility network with independent connection to each microgrid. Each microgrid has generation sources, storage source, electrical charges, two points of common coupling (one with the utility network and other with the neighboring microgrid) and a central controller. By performing...
Management costs in private clouds will be promisingly reduced by reviewing ‘operation history,’ which is defined as a holistic view of past operation executions. Operation history provides insights into breakdown of operations: the breakdown clarifies cost-dominant operations to be improved and repetitive ones to be automated. Towards obtaining the operation history, a conventional approach relying...
Technical systems which operate in the power industry are the critical systems of strategic importance. In case of such systems the task consisting in the avoidance of the failure occurrence has an extraordinary significance. The failure occurrence is interpreted as the transition of the system technical state from the area of the ability states to the area of the inability states. Therefore, the...
An optimized system management of a power system must take care of the actual operational and energetic duty of the power system distribution, promoting a high efficiency of power cables and avoiding their excessive gap on load and gap on lifetime. A procedure based on the Arrhenius model of the Thermal Aging of Insulating Materials allows implementing a tool to calculate the life loss and the residual...
The availability of sufficient and economic online capacity to support the network while encountering disturbances and failures leading to supply and demand imbalance has a crucial role in today distribution networks with high share of Distributed Energy Resources (DERs), especially Renewable Energy Resources (RESs). This paper proposes a two-stage decision making framework for the Distribution Management...
Due to the proliferation of microgrids in distribution networks and then the growing penetration level of Renewable Energy Resources (RESs) laid in these blocks, the operation problem of microgrids faces with serious challenges caused by RESs volatility and uncertainties; in addition, the uncertainties caused by DGs probable outages compound the situation. These challenges put emphasis on the importance...
The paper present the methods used in recent years in the national power grid to operate more efficiently as high voltage equipment. It includes shares of minor maintenance and operation undertaken by our company for management installations. It also briefly describes the results of applying new technologies and the technical analysis performed using such technical data. As part of asset management...
The large volumes of data that will be produced by ubiquitous sensors and meters in future smart distribution networks represent an opportunity for the use of data analytics to extract valuable knowledge and, thus, improve Distribution Network Operator (DNO) planning and operation tasks. Indeed, applications ranging from outage management to detection of non-technical losses to asset management can...
Distributed generation provides a new opportunity for modern power supply, but it also impacts on the operation and management of distribution network. Distributed power connected to the distribution network has changed the mode of operation of the distribution network from the original radiation type to a multiple power supplies network. The power flow direction of the traditional distribution network...
Many work related electric accidents occurred at workplace and they were fatal or non-fatal. The situation of electric accidents at workplace worldwide is investigated by reviewing the standard work practices, to offer perspectives on the types and kinds of statistics available, the factors regarded as influencing their occurrence, their consequences, and also methodological shortcomings. Worldwide,...
At present, the reliability and maintainability level of domestic helicopters has been greatly improved, however, since the logistics delay time is too long, the operational availability of helicopters has not been significantly improved. The paper analyzes the causes of this situation and puts forward the concept of the integrated system of operation maintenance support in order to realize the gapless...
The Ocean Observatories Initiative (OOI) consists of seven research sites with over 800 instruments collecting ocean, seafloor, and meteorological data in the world's oceans, extending from the Irminger Sea to the Southern Ocean. The scale with which data are produced from the instruments and their platforms presents key challenges, including how to (1) build data and information management infrastructure...
Renewable Energy Sources (RES) are becoming the backbone of the electric power infrastructure. Their role will be more dominant in the coming years, since the European Union aims to generate up to 80 % of the total electric demand by RES by 2050. However, the planners of the RES-based power plants are receiving more and more opposition from the local population regarding installing new power plants...
Recently, Increase in level of environment emissions and growing energy demand have became a serious concern and it has made clean and renewable energy sources more appealing. The micro-grid has attracted considerably good interest as it utilizes different energy sources all together and provides high quality and reliable electricity. In this work the planning and operational strategy of a renewable...
