Data Stream Load Shedding

Revision with unchanged content. A data stream being transmitted over a network channel with capacity less than the data transmission rate of the data stream causes sequential network problems. In this book, we present a new approach for shedding less-informative attribute data from a data stream to maintain the data trans mission rate less than the network channel capacity. A scheme for shedding attributes, instead of tuples, becomes imperative in stream data, since shedding a complete tuple would lead to shedding some informative, as well as less-informative, attribute data in the tuple. Since data shed at the source site may be of interest to the user at the destination site, we design a data recovery approach, which maintains the minimal amount of information for data recovery purpose while imposing minimal overhead for data recovery on the source site. Our load shedding and data recovery approach (i) handles wide range of data streams in different application domains, (ii) is dynamic in nature, since each load shedding scheme adjusts the amount of data to be shed according to the current load and network capacity, and (iii) is adoptive, which is appealing in an ever-changing network environment, and (iv) is not based on queries, but works on general data streams instead.

Under-Frequency Load Shedding Scheme For Island...

Abnormal conditions such as overload and generator tripping usually result in large excursion of power system frequency, voltage and other system variables. In this case, an effective method to prevent the electric power system from instability, frequency collapse and blackout is an under-frequency load shedding scheme. It is applied in order to maintain stability of the system, when the power system generation fails to supply the increase of load. Load shedding is a common technique to maintain the power system stability by curtailment of partial load in some part of the system. However, the load shedding techniques for an islanded distribution network should be treated differently from the transmission power system. A particular approach of under-frequency load shedding scheme is required for an islanded system which is known to be not as strong as the grid.

Electricity Demand and Load shedding: Impact on...

The ability of a country to meet its wider development objectives is largely affected by access to reliable energy. In Zambia, demand for energy, in particular electricity, has been rising due to economic activity in the country, particularly in the Mining, Agriculture, Manufacturing sectors and in all other businesses in general. As a result, load shedding and unannounced power-cuts have characterized Zambia's economy. Zambia`s business sector, both formal and informal, has not been spared and has been crippled and hit hard by electricity load shedding which is seen as a solution to the inability of the power utility to supply electricity to meet demand. Businesses and entrepreneurs are relied upon as the future engines of growth for the economy. It was therefore critical to understand the extent to which load shedding had affected this sector and how this could have affected the country`s economic development. The general objective of the study was to investigate the impact of electricity demand and load shedding on Zambian businesses and entrepreneurship.
