This paper identifies the problem of the non-intrusive load monitoring method of load disaggregation into separate appliances, when some local generators based on renewable energy sources are connected to the same grid, as they may be mismatched with loads variable in time. Three approaches of electrical energy consumption disaggregation from the energy generated from local renewable energy sources...
In recent decades, smart grid have become increasingly attractive to both energy producers and consumers. Amongst the main challenges for the successful realization of smart grid includes the integration of renewable energy resources, real time demand response and management of intermittent energy resources. Apart from smart grid, the development of micro-grids should take into consideration of issues...
The electricity sector liberalisation in Europe has contributed significantly towards the creation of competitive markets. The wholesale trading of electricity consists of a market-based segment often complemented by markets for ancillary services, including the provision of operating reserves. In this paper, the authors examine and classify operating reserves that are currently traded in the Netherlands...
The use of oxygen concentrators for the supply of medical oxygen in developing countries is increasingly becoming an alternative to conventional compressed gas cylinders, which are expensive to refill and logistically challenging to transport. Oxygen is important for obstetric, surgical, and an aesthesia care, as well as for the effective management of many diseases including severe sepsis, malaria,...
Consumer electronics products will be an integral part of the Smart Grid. Products will include smartened power consuming appliances, Consumer purchased power generators and in-home storage. These products lead to a more complex relationship between Consumers and utilities. We discuss how these products appear to the Smart Grid and the features required of the grid in order to manage them.
This paper presents a novel trust mechanism and web services, and introduces the application of Web Services, and designs for submarine power distribution system model, and discusses the core that the implement of the model controls and business processes.
The gas electricity generation is not only alleviating the present energy tight situation in our country, but also is one of the most effective ways to comprehensible use gas resources. A remote monitoring system for gas-combustion generator units based on Power Builder is presented in this information of paper. The system can remote control units start-up or shut-down, can remote measure automatic...
With the further construction of smart grid by State Grid, demand for measuring equipment including smart electricity meter and acquisition terminal certainly will increase. In this paper, a new testing system based on virtual meter is proposed, contraposing weakness in the function testing equipment and consistency test. Conveniently, it can bring power enterprises automation and reliability of testing...
Due to the growing demand on electricity, how to improve the efficiency of equipment has become one of the critical issues in a thermal power plant. Related works reported that efficiency and availability depend heavily on high reliability and maintainability. Recently, the concept of e-maintenance has been introduced to reduce the cost of maintenance. In e-maintenance systems, the intelligent fault...
Electricity market price may not always be a reference to determine the existence of market power. This paper discusses why electricity price in a day-ahead electricity market may exhibit peaks without representing market manipulation by any of the players. We use genetic algorithms to simulate the trading behavior of artificial agents in the spot market. Two case studies are reported and the results...
This investigation focuses on development of new methodologies for implementing power systems optimization for forecasting Location Marginal Prices (LMP) in deregulated electricity markets. The proposed approach uses the LMP method to show relationships between generator bids, power system constraints, and electricity demand. The proposed approach uses Unit Commitment, Economic Dispatch, and Optimal...
In this study, we fabricated in-plane thermoelectric micro-generators (4 mm times 4 mm) based on bismuth telluride thin films by using flash evaporation method. The thermoelectric properties of as-grown thin films are lower than those of bulk materials. Therefore the as-grown thin films were annealed in hydrogen at atmospheric pressure for 1 hour in a temperature range of 200 degC. to 400degC. By...
