WP 2

This WP evaluates existing communication networks in EP and TS from physical (geographical location) perspectives, topological architecture (e.g. flat, multilevel tree, star), used protocols on L2-5 (IPv4, IPv6, L2, L3), redundancy mechanisms, scalability possibilities and security mechanisms. TS network comprises wire line and mobile networks and both are treated in the same context. Evaluation is prepared from perspective of future dense DEG smart energy networks and its requirements for automatic control, monitoring and supervision. The purpose is to identify mechanisms and steps to converge both DSO and telecom communication networks into efficient entity supporting future smart grids.

The impetus behind the exercise is the investment and maintenance cost reduction of smart grids and sharing of burden by both DSO and telecom operator. Not directly, but rather implicitly by careful common planning, designing and implementation practices and sharing of communication resources for smart grid operations. We answer what parts of the network can be shared, and how to design future telecom networks to be useful in DSO smart grid applications, with special emphasis on security measures and logical domain isolation.

To assess the merits of convergence we define network key performance indicators (KPI) for communication and energy quality of service (QoS) that we use throughout the analysis, modelling, design, implementation phases (on the field trial) to guide us from pre-set initial design conditions through boundary limits to acceptable levels of KPIs with aim of serving system stability and scalability of future smart energy grids comprising dense DEG deployments. In full business model analysis we take into account broader perspective of smart grid energy market comprising various stakeholders (e.g. DSO, TSO, telecom, ancillary services provider, VPP service provider, e-car charging station providers and operators, regulator, new entities) and end users.

Results of WP2 are used as inputs for the underlying networking and service support for WP3 and WP4.
