Renewable Electric Energy Integration

The research evaluates how different market designs affect the European power grid's ability to integrate wind energy. It finds that the current zonal pricing system fails to reflect the physical reality of the grid, leading to inefficient network use and higher costs. Simulations using the MADRID and DRESDEN models demonstrate that a nodal pricing regime would increase international power transfers by up to 34% and generate annual system variable cost savings between €0.8 billion and €2.0 billion, depending on wind penetration levels.

• The current EU market design using zonal prices and aggregate transfer limits does not account for the physics of power flow, which can lead to infeasible power schedules, inefficient network use, and increased congestion.
• Simulations show that under a nodal pricing structure, price zones do not align with national borders and fluctuate based on wind output, indicating that zonal pricing cannot capture the grid's physical reality.
• A nodal pricing approach can increase international megawatt (MW) transfers between countries by up to 34% compared to the current EU model, suggesting the existing network can accommodate larger volumes of intermittent energy.
• The sum of all cross-border transfers reaches 43 GW at maximum wind output in both the Dresden and Madrid simulation models.
• Implementing a nodal pricing structure could result in annual system variable cost savings (primarily fuel costs) ranging from €0.8 billion to €2.0 billion, representing 1.1% to 3.6% of operational costs.
• Weighted marginal prices are lower under a nodal pricing regime in 60% to 75% of EU countries, and the use of costly real-time congestion mitigation measures like wind spilling and load shedding is minimized.
• The variation of congestion across different wind scenarios suggests that for zonal pricing to limit internal congestion, zones would need to be impractically small, further supporting the need for nodal pricing.
