Barriers for connection of DRES in distribution grids

To implement a massive integration of DRES in the distribution network, the first step is to identify the regulatory, technical and economical barriers that represent current obstacles to this integration.

1.     Methodology to access the barriers

The six local demonstrators led by the DSOs participating in IGREENGrid project are taken as the main reference for this analysis following a three step methodology. Each DSO was asked to identify the barriers that they will face while implementing the smart solutions proposed by their demonstrator.

 

Flecha Barriers

 

This process has allowed IGREENGrid team to identify the main barriers for DRES integration in Europe that can be classified in three different categories:

  • Regulatory;
  • Economical;
  • Technical.

 

2.     Main identified barriers to the massive integration of DRES in the distribution network

Eleven main barriers have been identified and classified taking into account which aspect is defecting.

Regulation does not allow DSO to control DER (including DRES)

3. Conclusion

The identified barriers are based on current problems encountered by the six IGREENGrid demonstrators extrapolated to a massive integration of DRES.

 

In addition, the results of other European projects (ADDRESS, More MicroGrids and EcoGrid EU) have lead to the similar barriers. It is logical to find that, as new solutions, the explored solutions will meet barriers to their implementations.

 

Once these aspects are solved, the main problem will come from the current regulation that seems to be behind the real needs of the Smart Grids solutions. Some regulatory changes are a mandatory step to make the massive integration of DRES cost-effective.
