Optimal share and contribution of bioenergy in the energy system and in coupled electricity and CHP-systems in Germany - system oriented evaluation of the cross-sector provision of flexibility of bioenergy plants through coupled electricity and heat generation (incl. e-mobility)

Brief description

The successive extension of the use of renewable energy in the German energy transition forces a restructuring of the entire energy system. This is connected with a set of new, innovative technologies and plant operation procedures as well as the necessity to shift the plant park more towards a flexible operation (demand response, storage, feed-in management, P2X, flexible conventional power plants, import/export; etc.). In the project OptiSys, the interaction of theses flexibility options is analyzed in detail from a systems point of view. Particularly the cost optimal integration of bioenergy into the energy system is further investigated and evaluated.

The overall project aim is to make the use of bioenergy in future, coupled electricity and combined heat and power systems more specific in Germany. Therefore, the defined quantity framework takes into account the electricity sector, but also the use of biomass in heat and transportation sector and the relations in-between. The interaction of bioenergy with other flexibility options is considered, as well as different technical solutions for the energy supply by biomass in the system is evaluated. The procedures and results are accumulated and documented in a methodological handbook and characteristic values and interactions will be provided for further research. Thus, an important contribution can be made for appropriate consideration of bioenergy in further energy system studies.

DIALOGIK contribution

As part of the project OptiSys the team of DIALOGIK is responsible for the participatory modelling part of the project. The DIALOGIK-team is planning, organizing, facilitating and documenting four project workshops, which are organized as round tables. The expert committee at the round table consists of actors from the field of bioenergy, energy system analysis and energy markets. This is to ensure that scenarios and results of completed and ongoing studies are taken into account adequately and that the results obtained in the project and the methodological handbook are developed and elaborated transparently. Thereby, DIALOGIK contributes to a transparent and practice-oriented project processing.
