半线性偏微分方程的完全倒向表示及其在电力系统负荷控制中的应用

A fully backward representation of semilinear PDEs applied to the control of thermostatic loads in power systems

Lucas Izydorczyk, Nadia Oudjane, Francesco Russo

摘要:

提出了半线性偏微分方程的一种完全后向表示及其在随机控制中的应用。在此基础上,我们开发了一个完全向后的蒙特卡罗方法,允许生成回归网格,在时间上向后,作为计算值函数。这在计算效率和内存方面提供了两个关键优势。首先,在感兴趣的区域中自适应地生成网格,其次,不需要存储整个网格。这种技术的性能进行了比较,在模拟传统的蒙特卡洛的前向-后向方法的控制问题的可调负载。

英文摘要:

We propose a fully backward representation of semilinear PDEs with application to stochastic control. Based on this, we develop a fully backward Monte-Carlo scheme allowing to generate the regression grid, backwardly in time, as the value function is computed. This offers two key advantages in terms of computational efficiency and memory. First, the grid is generated adaptively in the areas of interest and second, there is no need to store the entire grid. The performances of this technique are compared in simulations to the traditional Monte-Carlo forward-backward approach on a control problem of thermostatic loads.
