SCCER JA-RED - A list of possible ancillary services for enhanced grid operation and implementation of the most effective ones at the RE demo site - Deliverable 1.2.3

There is a need by distribution system operators and power suppliers to propose ancillary services to enhanced grid operation allowing the optimal deployment of photovoltaic panels, cogeneration technologies and distributed storage. This deliverable therefore proposes and evaluates the impact of a list of possible ancillary services for the injection of local renewable energy in the future low voltage grid. The novelty of the proposed building to district and district to grid approaches lies in the ability to generate a wide range of optimal energy transition scenarios using multi-objective optimisation techniques both at building and district level. The proposed approach differs from previous work by integrating ancillary services by optimizing simultaneously both sizing and operation of the district energy technologies. This deliverable demonstrates, on the reference case (TR3716), the implementation of voltage control ancillary services to integrate more renewable energy to the low voltage grid. In particular it exposes how advanced electricity tariffs can influence energy system design and operation to decrease stress induced by high PV penetration on the grid. The proposed implementation can be deployed in control boxes developed using open-source standards, such as mikrobus. Moreover, considering the transformer’s area as a relevant scale for the implementation of ancillary services, this work pave the way to the definition of a new geographical division for territorial energy planning aiming at the integration more renewable energy resources in urban areas.
