Group 1 - The rapid growth of clean energy generation is leading to increasing challenges in its consumption, particularly due to the inherent volatility and intermittency of wind and solar resources [1] - The existing power grid infrastructure struggles to adapt quickly to the demands of large-scale renewable energy integration, with current technologies like flexible coal plant modifications and large-scale energy storage not meeting the requirements for high proportions of clean energy [1] - Distributed renewable energy consumption is limited by the capacity of distribution networks, leading to increased instances of curtailment of wind and solar energy due to voltage and capacity constraints [1] Group 2 - The potential of virtual power plants to aggregate demand-side resources is crucial for enhancing the operational flexibility of grids with high proportions of clean energy [2] - Demand-side flexibility resources, such as electric vehicles and industrial loads, can provide a more cost-effective and broader range of adjustments compared to traditional grid infrastructure, but require organized aggregation to achieve scale [2] - Promoting local consumption of distributed energy and developing flexible local market mechanisms are essential for optimizing renewable energy utilization [2]
