随着可变可再生能源渗透率的增加，保持稳定的能源生产需要足够灵活的发电资源和调度算法，以适应可再生能源的不确定性。在这项工作中，我们研究了实时经济调度（RTED）算法的可行性，并建立其性能的基本限制。我们提出了一个联合的方法，资源采购和在线经济调度的可行性保证。我们的算法，可行固定时域控制（FFHC）是滚动时域控制（RHC）的一种正则化形式，它平衡了良好的近期需求预测与可行性要求的利用。与标准RHC相比，FFHC在实际负荷曲线上的经验评估突出表明，FFHC实现了接近最佳的性能，同时确保了RHC在高斜坡场景中变得不可行的可行性。
Maintaining stable energy production with increasing penetration of variable renewable energy requires sufficient flexible generation resources and dispatch algorithms that accommodate renewables’ uncertainty. In this work, we study the feasibility properties of real-time economic dispatch (RTED) algorithms and establish fundamental limits on their performance. We propose a joint methodology for resource procurement and online economic dispatch with guaranteed feasibility. Our algorithm, Feasible Fixed Horizon Control (FFHC) is a regularized form of Receding Horizon Control (RHC) that balances exploitation of good near-term demand predictions with feasibility requirements. Empirical evaluation of FFHC in comparison to the standard RHC on realistic load profiles highlights that FFHC achieves near-optimal performance while ensuring feasibility in high-ramp scenarios where RHC becomes infeasible.
