Modeling and optimizing a distributed power network : A complex system approach of the prosumer management in the smart grid (1305.4096v1)

Abstract: One of the most important goals of the 21st century is to change radically the way our society produces and distributes energy. This broad objective embodies in the smart grid's futuristic vision of a completely decentralized system powered by renewable plants. Imagine indeed such a real time power network in which everyone could be a consumer or a producer. Based on a coupled information system, each user would be able to buy or sell energy at a time depending price that would allow a homogenization of the consumption, eradicating the well known morning or evening peak. This attractive idea is currently booming in the scientific community as it generates intellectual challenges in various domains. Nevertheless, lots of unanswered questions remain. The first steps are currently accomplished with the appearance of smart meters or the development of more efficient energy storage devices. However, the design of the decentralized information system of the smart grid, which will have to deal with huge amounts of sensor's data in order to control the system within its stability region, seems to be still in search. In the following survey, we concentrate on the telecommunication part of the smart grid system. We begin by identifying different control level in the system, and we focus on high control levels, which are commonly attributed to the information system. We then define a few concepts of the smart grid and present some interesting approaches using models from the complex system theory. In the last part, we review ongoing works aiming at establishing telecommunication requirements for smart grid applications, and underline the necessity of building accountable models for testing these values.
