The European Union via its climate-energy packages set the goal of an energy efficient electricity grid with high level of security of supply and a high penetration of renewable energy generation. The so called Smart Grid aims to tackle this challenges. The Smart Grid provides an ITC (info communication) background and supplements new elements in order to support the economical dispatch, improve the reliability indicators and foster the integration of the renewable generation.

Microgrids will be an integral part of the future Smart Grid. The Microgrids are small scaled grids that are able to operate in a virtually or physically islanded manner. They aim to achieve balance between the local energy production and consumption. The dispatch of the many decentralized renewable or conventional generators is a great challenge. The Demand Side Management (DSM) is a solution for the economical dispatch of the intermittent renewable generation also considering the volatile energy prices.

In this thesis, the architecture of the Microgrids and the feasibility of DSM in the Smart Grid framework are introduced. The involvement of a common consumer’s appliances in the DSM is investigated. Also the guideline of an optimized scheduling algorithm is explained.
