Annotating and Integrating Legacy RDBMSs for the Utility Domain

Abstract

Since a few years the utility domain faces new challenges such as deregulation forced by the EU and its efforts towards improving efficiency of the energy markets and the increasing feed of renewable energy. These changes increase the amount of communication in and between companies, e.g. for trading at energy stock markets or for controlling offshore wind energy parks, thus increasing requirements for interoperability. Having a larger amount of small power plants like renewables and combined heat and power generation in the grid, the task for controlling them for assuring a stable grid gets much more complex. Therefore, many decisions have to be made automatically requiring a high data quality as decisions based on wrong data tend to be wrong. The proposed architecture provides a solution for both challenges.
