6 Vision The vision of e-balance is to develop a holistic hierarchical and decentralized ICT solution for Smart Grids that provides smart energy management for balancing the energy consumption and production, improves the grid resilience, supports a diversity of energy sources and stakeholders, considers the social aspects, market rules and the legal context, protects the data of the users following the data owner s security policy. 6

7 Objectives STO 1: Research on real-life aspects (economic and social) of the energy efficiency obtained by distributed and decentralized energy control and management. STO 2: Integration of communication technologies for decentralized power management with increased local decision support. STO 3: Flexible control and management algorithms for intra-level and interactive multi-level energy production, consumption and distribution. STO 4: Multi-aspect, detailed, reliable and reproducible evaluation of the proposed approach in real life scenarios. 7

9 The applicability of the solution Different stakeholder types Legislative diversity Diversity in energy sources Respecting market rules Satisfying needs and demands Protecting the privacy Increasing the efficiency Increasing the reliability Exploiting the fact that the energy network is fractal-like Realized as a flexible and innovative holistic approach 9

10 The use cases The Smart Grid is a complex system We defined 30 use cases to describe the addressed scenarios Each use case describes a sub-scenario/system feature Combination of these reflects the e-balance system The chosen use cases to be shown in our demonstrators Bronsbergen (the Netherlands) Batalha (Portugal) In-lab demonstrator (IHP lab) All rights reserved 10

15 Communication Platform security Scope: Mechanisms for privacy and security (library base) Privacy homomorphism, concealed data aggregation Scalable security mechanisms, public key infrastructure (PKI) Trust and group management (used by the middleware) Authentication, certificates (also revocation), group management, trust Node protection and maintenance (next to the e-balance architecture) Code update, node parameterisation and reset, node protection mechanisms All rights reserved 15

16 Energy Platform security Scope: Data access using the Data Interface operations Only authorized accesses allowed The middleware provides the data to authorized services only All rights reserved 16

17 The Data Interface The Data Interface operates on data structures and allows executing the following requests/operations: Reading, Writing, Subscribing, Unsubscribing. The data structure contains the following items: Identifier of the variable, e.g., current, voltage, temperature, wind direction, solar radiation, etc., Value of the instance of the variable, Temporal identification of the instance, e.g., a timestamp or a version number, Spatial identification of the instance, e.g., geo-coordinates, location in the hierarchy, Identifier of the instance owner, The privacy policy defined by the data owner All rights reserved 17

18 Year one results The definition of use cases and stakeholders' requirements (WP2) The analysis of the market and legal context User study to reveal users attitude and concerns (PL, PT, NL) Definition of the business framework Definition of the functional system architecture (WP3) Definition of the Data Interface that connects the two system parts Identification and design of innovative technical components (WP4, WP5) Definition of the energy balance and resilience models Initial definition of the security framework Specification of the communication platform First choices on available solutions, standards All rights reserved 18
