DeCAS - Demonstration of Coordinated Ancillary Services

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

DeCAS aims to research and analyse system services such as demand response and coordination of individual Volt/Var control concepts crossing traditional boundaries from high voltage, medium voltage to low voltage, as well as the mar-ket integration. It will further include the integration of relat-ed monitoring and controls in process-control systems. The result will be an orchestration of the power system via hier-archical and integrated network control, taking into consid-eration the market integration of flexibility and stakeholder involvement focusing on consumers and networks opera-tors.

Main Objectives

The main objectives of the DeCAS project are:

  •  To research and analyse the coordination of ancillary services such as, aggregated “prosumer” response con-trol 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 related to monitoring and controls in process control sys-tems as well as to existing and future flexibility markets. LV grids are usually not automated yet and there are hard-ly any measurements available. Thus the project will eval-uate 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

Technology Development

The project DeCAS is going to develop and investigate solutions for the coordinated activa-tion 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 to flexibility markets. Through the field tests, it is possible to solve prac-tical implementation issues e.g. due to the interconnection of installed and established products with new solutions from IoT world. Additionally in 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 for solutions gaining flexibility from a large range of resources. A reason-able 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 con-trol in order to involve for instance 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.
