A Mid-and-Long-Term Flexible Trading Method Considering Uncertainties of Renewable Energy Based on Capacity-Credit Curves
摘要
The current trading methods for mid-and-long-term transactions are insufficient to meet energy demands and limit trading opportunities as renewable energy resources integrate into the power grid. This study proposes a new approach to flexible trading for mid-and-long-term energy transactions, which effectively addresses the inherent uncertainty issues associated with renewable energy sources. A case study conducted in Shandong province, China validates the mode, revealing substantial improvements in both the volume of renewable energy transacted and suppliers’ profitability while preserving the original adequacy through the utilization of capacity-credit curves. Furthermore, the proposed method is particularly suitable for aggregated resource transactions due to the complementary nature of diverse renewable energy resources.
