Demonstration of

coordinated ancillary services covering different voltage levels and the integration in future markets

Main objectives of DeCAS project: 

 

To research and analyse the coordination of ancillary services such as, aggregated “prosumer” response control reserve, individual voltage control and reactive power management concepts over traditional boundaries from high voltage, medium voltage to low voltage.

 

To develop approaches and concepts for a coordinated control considering the different objective functions of individual voltage levels. It will include the integration of monitoring and control technologies in process control systems as well as the integration in existing and future flexibility markets. LV grids are usually not automated yet and there are hardly any measurements available. Thus the project will evaluate promising concepts for LV grid operation tools and processes, and how they can interface with MV/HV SCADA (supervisory control and data acquisition) DMS (distribution management system).

 


Main results of DeCAS project:


Technology Development:

The project DeCAS is going to develop and investigate solutions for the coordinated activation of ancillary services over traditional boundaries from high voltage, medium voltage to low voltage considering the different objective functions of individual voltage levels. The project includes the integration of related monitoring and controls in process control systems as well as the potential integration of flexibility markets. Through the field tests, it is possible to solve practical implementation issues e.g. due to the interconnection of installed and established products with new solutions from the "Internet of Things" (IoT) world. Additionally, in the course of the project, existing grid codes are going to be analysed and recommendations for a further development will be derived.

Market Integration:

DeCAS is researching solutions for gaining flexibility from a broad range of resources. A reasonable amount of possible flexibility is not owned by DSOs, but rather by prosumers or independent plant operators. DeCAS will analyse market-based solutions as part of network control, for instance in order to involve prosumers, covering both generation and demand side management, in future flexibility markets.

 

Stakeholder Integration:

Via demonstration activities and description of best practices the DeCAS project will reduce the barriers for engaging the prosumers in smart grid topics by investigating and evaluating how this unrealized potential of prosumers participation can be realized for the benefit of all stakeholders involved. Business models as well as future roles for prosumers and distribution network operators are important parts of this investigation.
