Smart Energy System Integration of Photovoltaic: From Strategic and Research Innovation Agenda to EU Funded Projects

The EU has set an ambitious target to reach climate neutrality by 2050, with a rapidly rising share of PV and wind generation reshaping the energy system in terms of planning and operation. A high penetration of PV systems requires advanced monitoring and control systems and techniques, as well as technology that provides system stability and minimises congestion during peak production hours. In this context, Challenge 4 of the Strategic Research and Innovation Agenda (SRIA), developed within ETIP-PV, is dedicated to “Smart Energy System Integration of Photovoltaics for Large-Scale Deployment and High Penetration”. Despite the Challenge identified six roadmaps, a systematic and scalable synthesis of the thematic evolution and strategic relevance of grid integration PV challenges, solutions, and evolutions remains limited in relation to EU-funded projects. This paper introduces an LLM-based methodology for analyzing a decade of EU-funded projects data, mapped to the Challeng 4 SRIA roadmap, and extracting indicators to reveal trends, dominant themes, and gaps. The framework provides a reproducible methodology to possibly guide research directions, funding priorities, and policy development.
