Efficient storage for Smart Grid
Smart Grid is an increasingly popular term that means the implementation of an intelligent management system for the distribution of electricity, gas, water, etc. The main objectives of the implementation of e.g. electrical distribution systems are an increaseing grid reliability, energy efficiency opportunities, a reduction of the impact of electricity infrastructure on the environment and the management of energy from distributed and renewable energy sources. From the distribution company's point of view, no less important will be areduction of the costs associated with the operation of the network and optimizing investment, and a better utilization of the network. One of the serious challenges is the management of measurement data. Any Smart meter unit, installed in a house, continuously logs energy consumption and reports this information to the distribution center. A typical company has hundreds thousands or even millions of unique customers (smart units) which might cause terabytes of data yearly. Moreover, the nature of measurement data, which comes at regular intervals, where information has a natural order in time and requires some unique analytical techniques and high workloads, means that traditional database systems have a number of downsides which emerge on a higher scale.
This specific data can called time-series data.
