C / sells

from Wikipedia, the free encyclopedia

"C / sells: Large-scale shop window in the solar arc of southern Germany" is a research and implementation project for intelligent energy networks (" Smart Grids "), which is part of the SINTEG - Smart Energy Showcase - Digital Agenda for the energy transition in Baden-Württemberg , Bavaria and Hesse is implemented.

The project funded by the BMWi on the basis of a resolution by the German Bundestag is dedicated to the digitization of energy supply networks in order to take account of the growing share of renewable energies and their high volatility compared to thermal power plants. The program addresses the need to prepare the current national power grids for the requirements of volatile power generation , which is associated with a high proportion of renewable energies . C / sells is one of the five showcase projects funded under the program. The project researches and tests the digitization of network infrastructures with a focus on decentralized energy generation and photovoltaics , with a range of around 30 million people, it is the SINTEG showcase that covers the majority of German households and the main industrial consumption areas in southern Germany .

C / sells is carried out as a decentralized large-scale project in the group of a consortium of 58 partners and develops and analyzes not only the technical components of intelligent energy networks, but also the organizational, legal and economic framework. The concrete implementation will be tested in 35 demonstration cells and the social involvement in 9 so-called participation cells.

Goal setting

C / sells operates within the framework of the objectives of the SINTEG program. The analysis, development and implementation of the following aspects are carried out:

  • Safe and efficient network operation with a high proportion of renewable energies
  • Use of efficiency and flexibility potential (market and network side)
  • Efficient and safe interaction between all players in the intelligent energy network
  • More efficient use of the existing network structure
  • Reduction of the need for network expansion at distribution network level

As part of this, problem definition, structuring and demonstration of the technical and strategic concepts are tested and evaluated under laboratory, then real and market conditions. The implementation is controlled by the central idea within the framework of C / sells.

The C / sells guiding principle

The guiding principle specifies the strategic direction, as well as the approach and basic tools of the project; it defines three properties as central:

  • Cellularity: Energy systems are organized or viewed in cellular form. The cells are permanently connected by the existing electricity networks (distribution network and transmission network), but aim for generation and consumption in the area of ​​the cell.
  • Participation : The energy transition should be designed with the involvement of society as a whole, not by a few actors as has been the case up to now. The principle of participation is addressed both in the overall project and specifically in work package 2.7, in which nine municipalities are analyzed as "participation cells" with extensive participation and communication measures.
  • Diversity: Since the framework conditions are always different, it is important to find suitable solutions for each cell. Thus, an approach that is applied to all cases is not propagated, but rather a plurality is intended.

The properties are implemented from a technical and economic perspective using three basic instruments:

  • The Infrastructure Information System includes the development of the requirements, the hardware, its transmission concepts, standards, processes and use cases.
  • The coordination cascade includes the coordination of the various actors who are active on the various network levels. The goal is safe and resilient operation across all network levels (transmission network, distribution network).
  • The regionalized trade in energy and flexibilities enables the economic exploitation of existing flexibility potential. These can be made available for grid-related services and thus monetized.

The project structure

The overall project consists of seven sub-projects (TP). These seven sub-projects are divided into more than 60 work packages that deal with the different contents of the project. The project is organized on a decentralized basis, the individual work packages act autonomously, but are in constant communication with one another, coordinated by sub-project 1, project management.

Subproject 1 - project management

This sub-project coordinates the collaboration between the C / sells partners and organizes reporting and contracts. It consists of two work packages (WP):

  • AP1.1 includes the organizational and process support of the overall project and all sub-projects
  • AP1.2 includes the technical support of the overall project through a common online collaboration platform

Subproject 2 - environment design

Subproject 2 is dedicated to the overall integration of the activities and interests of all partners into one It consists of nine work packages:

  • WP2.1 coordinates all activities of the C / sells sub-project 2.
  • WP2.2 serves to develop a uniform guiding principle for the project.
  • AP2.3 evaluates new business models that are made possible in connection with or through intelligent energy networks.
  • WP2.4 examines which incentives for prosumers through
  • AP2.5 Regulations and Energy Law
  • WP2.6 evaluates the business use cases (BUCs) generated in the model
  • WP2.7 includes the coordination and implementation of all participation activities to involve citizens and other social interest representatives (so-called stakeholders) . The Ich-bin-Zukunft.de campaign was created for citizens.
  • WP2.8 considers the scalability of the results acquired in the project through normalization and standardization
  • WP2.9 evaluates the organization of cellular systems

Subproject 3 - Infrastructure Information System (IIS)

  • WP3.1 coordinates all activities of the C / sells sub-project 3.
  • AP3.2 develops the infrastructure information system
  • WP3.3 Implementation of intelligent measuring systems (so-called iMSys, also known as smart meters)
  • WP3.4 extrapolation, prognosis and accounting

Subproject 4 - Organization of intelligent networks

Subproject 5 - Methods for intelligent properties and markets:

Subproject 6 - Demonstration of intelligent grid cells

Subproject 7 - Realizations of prosumers for properties in markets

C / sells partner

As part of the project, 58 partners, some of whom are fully funded, some of whom are associated with the project, are represented. The partner group is organized democratically, the elected network coordinator EAM is the central contact person for the BMWi and the project management agency, as well as commissioning the project management.

The participating partners come from a. the areas:
