Smart Grids require a system approach and modularity

Smart Components will rely on nodes of integration in the information system

Solutions for e-mobility should be simple, economical and centered on customers

Components for smart grids and e-mobility

A system approach that require components

Smart Grids need a system approach based on interoperability, common requirements and standards

The need is not « equipment » but components that are standardized, modular in their design and could be integrated as nodes in the information architecture

Example of this approach in the Synerdis Project : Harmonization of requirements between utilities

(France, Hungaria, Slovakia, Germany and UK) Definition of « smart grids » Functional Units that

can embed communication, metering, fault detection, sensors, ….

Smart components will rely on nodes

The main difficulty is to specify separately electric equipment and information system : design of the smart grids should rely on an integrated approach

The EU FP7 project addresses 3 key R&D objectives :

1. Secondary susbstation nodes (SSN) : gathering information and making the appropriate control for the futur of distribution network

2. A software layer to couple operation of SSN into the Information System of utilities (supervision, management, DMS…),

3. A modular communication architecture based on protocols from standards that would bring sufficient flexibility to address future needs

Example of functionalities covered by e-nodes

Core functionalities : Monitoring and data management Basic automation Metering infrastructure Remote action

Advanced functionalities State estimation Volt and Var control Load management Decentralized intelligence Connection of EV

Solutions of E-mobility should be simple, economical and centered on customers

The main stake of e-mobility is management of peak power ! Smart charging should be enabled and signals managed by

network operator to prevent overload Metering and billing should include very simple and economical

solution such as tariff signal sent by PLCUsers should be at the center of this integration
