Recently, with China's economic development into a new normal state, slow growth of the power demand and rapid expansion of new energy sources puts coal-fired power at excess risk in the short term. For Anhui Province, a coal-based province, more attention should be paid to the development direction of future coal-fired power. Considering the prospect of coal-fired power development in China and the...
A datacenter's power consumption is a major contributor to its operational expenditures (op-ex) and one-time capital expenditures (cap-ex). The recurring electricity cost is often in large determined by datacenter peak-demand under peak-based pricing which is employed by major electric utility providers. There is a growing interest in reducing a datacenter's electricity costs by using throttling techniques...
Electricity theft is a major contributor of nontechnical losses in the distribution systems of the smart grid. However, owing to the resource-limitations of smart meters and the privacy requirement of electricity usage data, theft detection has become a challenging task for electric utilities. To address this problem, a Distributed Intelligent Framework for Electricity Theft Detection (DIFETD) is...
Since the Fukushima Daiichi nuclear power plant disaster in March of 2011, the government of Japan has been reforming the electricity supply system in stages to reduce the independence on nuclear power. The Feed-in Tariff system for renewable energy has been implementing from July 1, 2012. More than 4 years after the beginning of the Feed-in Tariff system in Japan. It significantly enhanced the usage...
There is a great deal that concerns international financiers in the potential electricity market in underdeveloped countries such as Iran. Renewable energies like sun and wind are becoming attractive fields of investment in these market since the past decades. There is a good situation for investors in Iran where energy intensity is three times more than the world average. However, this market has...
Understanding the causal directions between electricity consumption (EC)/electricity production (EP) and Gross Domestic Product (GDP) is helpful for policymakers in order to design, redesign, and implement effective energy policies. Although there are many studies on this issue, no consistent conclusion exists. In this paper, we provide an updated analysis of such relationship for Mexico. We employ...
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...
One of the hottest topics in the electric utility industry today is Cyber Security. How can we protect our Nation's critical electric infrastructure from malicious events with intentions that range from crippling our electric system to stealing our customers' private data from the utility billing system? This article will explore some of the options that small electric utilities have for implementing...
The US electric grid is undergoing profound transformation. New motivations and developments are changing longstanding models and methods. The historical underpinnings of the legacy grid have eroded while new alternatives have arisen to change how electric power and energy is produced, transported, utilized and managed. There is an unprecedented, accelerating proliferation of dynamic new components...
Smart Grid allows users to deal with information related to the electricity usage via IP networks, and then guarantee of both validity and privacy of information is necessary for users. In our future scope, the electricity bill used by consumers may be charged to the consumers themselves via the Smart Grid, even outside their homes. Such information is strictly related to privacy of consumers and...
The problem of designing Bayesian incentive compatible, individually rational and revenue maximizing auction for multiple goods and flexible customers is considered. The auctioneer has M goods and N potential customers. Customer i has a flexibility set ϕi which represents the set of goods the customer is equally interested in. Customer i can consume at most one good from its flexibility set. We first...
Power load analysis is important for optimizing resource allocation, planning the production of electricity, and predicting power markets. Yet, it is challenging, since load data exhibit both periodic and stochastic features, and is affected by a multitude of factors including social, economic, political, and climatic factors, as well as industrial structure, living standards, and user behaviors....
IEC 61850 is a series of international standards for various aspects of substation automation systems (SASs) including functional elements named logical nodes (LNs). Currently, intelligent electronic device (IED) vendors individually select LNs to build their own IEDs, so it is difficult to construct a SAS in a multivendor environment. One solution is to create functional specifications that can be...
The transformation progress of the smart grid challenges the market players' business models. One of those market players is the Distribution System Operators (DSOs). This paper aims to elaborate how smart grid influences the DSOs' business models with case studies of two Danish DSOs — EnergiFyn and TREFOR. The main findings indicate that the Danish smart grid transformation process influences the...
This paper proposes see how the new technologies related to the concept of smart grids can influence on the current technological model of power transmission infrastructure in NAFTA. The comparative analysis of energy integration and smart grid technologies applied in bloc countries show that: for over four decades began on robust initiatives for cross-border electricity interconnection in North America,...
This paper gives an instruction of the robotics applied for power industry in China. Firstly, it is the instruction of the actuality of the electric power industry in China. And we introduce the robotics applied in the field of the power generator, for different application requirements, include generator detection robot, robot in nuclear power station and for the hydropower station detection. Then...
Augmented Reality (AR) promises to revolution the maintenance field in general with relevant contributions to High-Voltage Systems. The value-added can came from several aspects, namely the increasing security and reducing time and costs of intervention. However there are some aspects related to AR state-of-the-art that do not permit yet to reach all of their potential, namely the necessity of use...
This paper presents a new formulation for placement of switches in distribution of electric power. An approach for determination of the location of tie switches and section switches using a multi-objective microgenetic algorithm is proposed. In the procedure, load importance, reliability index, remote or manual controlled switch and investments costs are considered. The results are based on simulations...
Internet infrastructure is highly distributed among different private and public sector entities. Although networks using Transmission Control Protocol (TCP) are highly resistant to failures — especially when multiple paths from sender to receiver exist - they have the potential to fail if a concentration of high-capacity routes between a particular sender and receiver become unavailable. The geographic...
