The integration of solar and wind power poses specific challenges as system operators pursue low-carbon investments and long-term energy sustainability. As these variable renewable energy (VRE) sources reach high shares of power generation, power systems must be increasingly flexible to maintain the balance of supply and demand over each day or year.
In response, policy makers and system operators around the world seek new enabling technologies, business models, market designs and system operation measures, aiming to make optimal use of VRE in this evolving landscape. Innovation initiatives, therefore, look for solutions that boost system flexibility.
The International Renewable Energy Agency (IRENA) has analysed the innovation landscape for VRE integration, mapping and categorising innovative solutions and on-the-ground examples.
The resulting report aims to provide a guide to current innovations, either under development or already in use, in different settings across the globe.
The resulting framework is meant to support informed decision-making on the best solutions for each different power system. The report concludes with an eight-step plan for power-sector transformation:
