Large-scale integration of RES and EE in communities with more than some 1.000 inhabitants requires a comprehensive technical and organisational management of a large number of distributed energy generation, consumption and eventually storage units. It also requires the comprehensive involvement of a large number of individuals and different groups of society, including local companies. The lead objective of applying comprehensive energy management in the 4 communities can be broken down in the following specific objectives:
- Further developing and adapting three existing environmental and energy management systems: DEMS, E(ner)MAS and MFM.
- Combining the three management systems in a comprehensive (4 local and 1 global, inter-communal) management system for technically and organisationally connecting a bundle of complementary measures acting at different levels.
- Applying the comprehensive energy management system in the 4 core communities, thus dealing with the complexity of large-scale RES and EE integration deriving from the large size of the communities and demonstrating the feasibility of managing distributed energy generation
Technical energy management with DEMS
DEMS (Decentralised Energy Management System) was designed by SIEMES in order to operate a large number of small, decentralised energy generation and consumption units with the same accuracy and level of control as it is state of the art for single large power plants. The technologies that can be connected to and controlled by DEMS cover both RES and EE technologies and energy in the form of heat as well as electricity. DEMS allows to implement both Demand Site Management (DSM) as well as Least cost planning (LCP) on a small regional level and can take weather forecasts into account. The various small and decentralised units are integrated through modems and data lines and can be centrally operated. In this project, DEMS will be configured in a cascade structure, including 3 local sub-configurations in the core communities Weilerbach, Tulln and Redange, and an interconnecting part allowing for central monitoring and control of all involved communities. The installations in the community Slubice will be directly monitored and controlled through the central DEMS unit, in order to get experience with the broadest possible range of operation options.
Organisational energy management with E(ner)MAS
A CONCERTO process in a community needs to involve the local administration and local companies. For this reason, it is similar to a number of joint public-private processes that are already well known from the implementation of environmental management systems, that the latter could strongly foster the implementing the CONCERTO processes themselves. While DEMS is an energy management system consisting of hard- and software, the existing environmental management systems are pure orgware, i.e. it consists of procedures for managing organisations like companies or communities for improving their energetic and more broadly environmental performance.
Two aspects in the existing environmental management systems need to be further developed in order to make them applicable to CONCERTO communities:
- Step-by-step nature of processes with intermediate certificates, thus allowing to better involve SME
- Consideration of energy aspects and development of a specific low-treshold energy management orgware (EMO) and audit certification system based on EMAS: EnerMAS easy
This will be done, thereby facilitating the use of Kyoto protocoll mechanisms and the implementation of eco-taxes.
Further optimising energy management with MFM
Material Flow Management (MFM) aims at optimising material and energy flows in complex systems. Aside from enhancing energy saving and renewable energies MFM traces embedded energy potentials like waste to energy, energy content of food chains and other system immanent energy flows. In a second step, MFM uses market and business strategies to turn the potentials into regional added value. Thus MFM is able to take of input from DEMS and E(ner)MAS, but the scope of options investigated by MFM, and its potential for optimisation is much larger than for E(ner)MAS and DEMS. In the framework of this project MFM will be used to further optimise the sustainability of the communal energy systems.
