Reducing barriers hampering large-scale integration of PV electricity into the distribution grid (PV GRID)

Download PDFDownload PDF
The overall goal of the PV GRID project was to reduce the regulatory, normative and administrative barriers hampering the large-scale integration of Photovoltaic (PV) power into the electricity Distribution Systems (DS) while facilitating knowledge transfer between European countries. In this sense, the project focused primarily on enhancing PV hosting capacity in distribution grids by supporting the adoption of available technical solutions and, secondarily, on assessing national frameworks for the development of PV installations. The assessment and comparison of national frameworks for developing and operating PV systems in 16 European countries have been gathered in an online database, thus taking forward the successful endeavor of the previous IEE funded project PV LEGAL. But most importantly, the project identified sets of suitable technical solutions for large-scale integration of PV according to the various implementing actors (DS operators, prosumers or both). Based on the effectiveness of these technical solutions and on the feedback received from the involved sector experts, a roadmap for "Increasing PV Hosting Capacity" has been developed. The roadmap provides policy makers with a first indication on their current PV hosting capacity, technical solutions and, regulatory and normative recommendations that could facilitate large-scale integration of PV in their distribution networks.

Results

  • The European Advisory Paper provides an overview of the issues and barriers that, at both European and national levels, need to be addressed in order to enhance the distribution grids capacity for PV. The document includes a set of recommendations for the implementation of the identified technical solutions and provides a more detailed analysis for a set of "Focus Countries": Germany, Italy, Spain and the Czech Republic.
  • Updated PV LEGAL/ PV GRID database in which detailed qualitative and quantitative information on administrative processes and barriers faced by PV system developers in each of the 16 participating countries.
  • 16 National Forums presenting to the national PV stakeholder community the status quo of administrative procedures and barriers for PV in their country and other European countries, in parallel with the first outcomes of the discussion on specific PV grid integration issues.
  • 16 National workshops promoting and enforcing the normative and regulatory recommendations of the Advisory Paper in order to create a better framework for enhancing the hosting capacity and the operation efficiency of the distribution grid thus allowing a larger scale penetration of PV and other intermittent RES-e generation technologies.
  • One main final European event organised in Brussels, to present to the European Institutions, energy sector associations and other organisations the results and recommendations of the PV GRID initiative.
  • Initiation of processes for the reduction of regulatory and normative barriers towards large-scale integration of PV and other intermittent RES-e generation technologies into the distribution grid. 
  • Initiation of processes for the improvement of national administrative frameworks for developing PV installations in the 16 addressed EU countries consisting in reduced barriers and more efficient administrative procedures.

Lessons learned

  • The choice and the effectiveness of the various solution identified depends on the planning process, network characteristics and/ or feeder constrains and, of course, the national economic context.
  • The participation of all key national stakeholders (e.g., DS operators, PV industry representatives, policy makers, regulators) in the discussions of solutions and approaches is of paramount importance to a successful implementation.
  • European-level network codes and standards can significantly impact distributed generation and network infrastructure operation.
