Power system impact studies are often the first steps taken towards defining renewable targets. It is important that commonly accepted standard methodologies are applied related to these issues. IEAWIND and IEA PVPS have issued Recommended Practices for Wind/PV Integration Studies to provide researchers, consultants, and system operators with up-to-date guidelines on how to perform renewable power system studies.
The second edition of the report published in 2018, extends recommendations for wind integration studies to also include solar PV and distribution networks, on top of transmission network issues.
Recommendations are based on more than 10 years of work within the International Energy Agency Wind Technology Collaboration Programme (IEA Wind TCP) Task 25: Design and Operation of Power Systems with Large Amounts of Wind Power and the IEA Photovoltaic Power System Programme (PVPS TCP) Task 14: High Penetration of PV Systems in Electricity Grids.
