Electric power systems across the world are facing significant challenges at several levels due to the increasing levels of Distributed Energy Resources (DER) penetration. These changes are affecting the way how electric power systems and distribution systems in particular are managed.

Different challenges are now present, in particular at low voltage distribution networks, such as the growing penetration of inverter-interfaced renewable sources and storage devices, including electric vehicles, as well as the implementation of demand response strategies, the establishment of microgrids capable of autonomous operation even in islanding conditions and the massive deployment of smart meters.

The ADMS4LV project aims to develop an advanced distribution management system capable of tackle the most prominent operational challenges in LV networks, leveraging the smart grid technologies expansion to the lower voltage levels of the electrical power and energy system.
 
The SmartGrids for LV Networks
A smart grid is an electricity network that can intelligently integrate the actions of all users connected to it – generators, consumers and those that do both – in order to deliver efficiently sustainable, economic and secure electricity supplies.
 
The LV Network management challenges

Consumers Integration: One of the aspects that characterize the concept of smart grid is the inclusion of consumers as an entity that may participate actively in the network management.
 
Distributed Energy Resources Integration: The integration of DER is expected to be one of the major contributions for increasing the network’s efficiency, as it promotes de use of renewable energy resources to produce energy close to consumer’s premises.
 
Complexity: The concept of smart grid is the result of combining multiple systems which are interdependent of each other, resulting in a high complex system.
 
Network’s Legacy: As LV networks may present several decades of lifetime and due to the permanent changes in their constitution.
 
Regulation: As LV networks may present several decades of lifetime, are build for older regulations that are being updated as new challenges appears.
 
The ADMS4LV benefits

The ADMS4LV offers effective solutions dedicated to LV networks for managing, the big quantitates of data that there will be available. As the AMI may provide several electrical measurements from different locations of the network, the ADMS4LV leverages this information to increase exponentially the DSO’s capability for monitoring the network. Nevertheless, this monitoring is performed in an efficient way through the use of State Estimation algorithms with the ability for selecting the most relevant measurements and the IEDs that maximize the observability of the network.

The ADMS4LV project uses communication standards and protocols, guaranteeing interoperability, which is of the utmost importance in order to achieve an effective implementation of the smart grid concept. In addition, there is also interoperability between the new proposed tools, under the scope of this project, and higher hierarchical level systems such as the coordination between automatic fault detection and localisation tools with Outage Management Systems (OMS).
