Customer rephasing is one of the most efficient techniques for balancing loads, reducing losses, and improving electricity quality. Traditionally, phase changes were performed by an operator, interrupting the supply during the process. Instead, a more recent approach proposes using phase switching devices that dynamically and imperceptibly transfer...

Determining the topology of the low-voltage grid in the electricity distribution network is problematic. In large cities, grid changes take time to be updated in the Geographic Information Systems (GIS), contain human errors, or produce other problems. Even more, using only one-phase connection in buildings with 3-phase energy is very common due to cost. In both cases, the information about phases and transformer substations is unknown or contains errors, increasing costs and decreasing service quality. In the case of old buildings like hospitals that have undergone several renovations over the years, the problem is worse because, usually, the blueprints do not match the reality of the circuits. The objective is to develop a system based on data analysis (PhID) that uses commercial smart meters data in order to detect the topology of the network. The system must work with very little data and be resilient and fully automated (no data cleansing or parameter adjustment of any kind).

In the current project, tools based on Artificial Intelligence are used to tackle the Peak Load Problem, such as Multi-Agent Systems, Artificial Immune Systems, and Genetic Algorithms. From the energy viewpoint, the project uses a Demand-Side Management approach to control energy demand. This strategy is oriented to reduce the impact of the Peak Loads transparently or imperceptibly to the electric consumer.
