摘要:

本文提出了一种通用且实用的方法,无需依赖历史观测数据,即可估算在配电系统运营商(DSO)电网中最优控制可延迟负荷的经济效益。我们通过使用非参数全局预测模型,学习柔性负荷对随机控制信号的模拟响应来实现这一目标。将该预测模型纳入优化问题,便可求得最优控制策略。我们将该方法应用于通过纹波控制运行的电热水器和热泵,展示了如何表征并控制包括回弹效应在内的灵活性。最后我们证明,该预测器的精度足以完全跳过模拟环节,直接使用预测器估算灵活性控制的经济效益。

英文摘要:

This paper proposes a general and practical approach to estimate the economic benefits of optimally controlling deferrable loads in a Distribution System Operator's (DSO) grid, without relying on historical observations. We achieve this by learning the simulated response of flexible loads to random control signals, using a non-parametric global forecasting model. An optimal control policy is found by including the latter in an optimization problem. We apply this method to electric water heaters and heat pumps operated through ripple control and show how flexibility, including rebound effects, can be characterized and controlled. Finally, we show that the forecaster's accuracy is sufficient to completely bypass the simulations and directly use the forecaster to estimate the economic benefit of flexibility control.
