The overall objective of WP2 is to provide a synthesis of alternative system architectures for
the future Danish electric power transmission and distribution system.
A power system architecture is the specification of operating objectives, functions and components
and their mutual relations in the electrical power transmission, distribution and user
(generation/consumption) subsystems including associated subsystems for data acquisition,
coordination, control, protection and their links through communication networks. The architecture
defines accordingly the services the power system and its components offer to the
energy system as a whole and to its own internal subsystems and the intelligence provided
by the data acquisition, coordination, communication and control subsystems. The architecture
does not presuppose a particular technological solution for subsystems. Rather, power
system architectures may be implemented by alternative technologies and composed of
different technologies serving different purposes (e.g. markets for coordination and protection
schemes based on a hierarchical command structure).
According to the abovementioned definition, the market based power system architecture is
an architecture which uses market mechanisms as a technology to manage energy generation,
transmission, distribution and consumption resources in the power system.
Definition of a system architecture requires a combination of analysis of possible solutions
and a top down approach to solution independent system requirements and associated
architectures. Therefore, the work has been divided into the following three subtasks:
• Review of innovative power system solutions
• Analysis of requirements
• Possible System Architectures
The three subtasks are specified in more detail below and results of the work are presented
throughout chapters 1.1, 2 , 2.2. WP 2 utilizes results from the EcoGrid.dk WP4 (measures).
