Abstract:Uncontrollable renewable energy sources, such as solar panels and wind turbines, as well as the increasing use of electrical devices leads to a mismatch between energy supply and demand. A solution to this is to regulate the demand side, such that it matches with the variable supply. In order to control the power consumption of devices efficiently, the active control methodology has been developed, for which a dedicated communication infrastructure is needed. The addition of a communication layer to the electricity grid, in order to measure and control the energy usage, forms the smart grid. In this thesis, various approaches for deploying the communication infrastructure necessary for the decentralized control of embedded devices are investigated. The general layout of the communication network in a smart grid is addressed. Relevant communication technologies and protocols are examined using the OSI-model. The requirements for a proper performance of the active control methodology are set up, followed by possible solutions based on these. A Wireless Mesh Network seems a suitable option for connecting smart meters. In order to acquire a robust and flexible system, the paradigm of Software Defined Networking is promising. An emulation is used as a testbed in order to investigate the behavior of the application as if it were deployed in a real communication network. Reproducible experiments using various topologies have been set up. The overall performance of the current implementation complies in great extent to the requirements, but scalability might be the limiting factor. Deliberately inducing network failures resulted in poor performance of the algorithm. An approach for the infrastructure, as well as small modifications on the implementation are given based on literature and experiments.
