Smart Control Architecture for Smart Grids - SAGA (2012-2016)

Project leader: Prof. Matti Lehtonen

The key motivation of Smart Grids is the integration of renewable power generation, distributed energy resources and energy efficiency in power and energy systems. As a control task this is huge, involving millions of actors, and is not possible using the present day centralized solutions. Instead, the operation and control must be decentralized and divided into hierarchical levels. A proper coordination is needed between the levels and among different actors at the same level.

The challenge is to develop control architectures, with associated control functions and procedures, such that overall energy efficiency is maximized and that the energy system reliability and security are ensured. To achieve this goal, this research combines three different power system levels (centralized production – distribution system – customer & local resources) with energy, network and market associated control tasks and functions with different time spans, extending from seconds in the case of power system disturbances and capacity adequacy management to the scale of hours in the case of energy efficiency optimization. Analyzing and optimizing the performance of this kind of control architecture requires a cross-domain perspective.
