我们考虑电网的最优电力调度问题，包括发电机和电池以及需求。由于网格可能非常大，我们考虑以分布式方式优化该网格，其中每个局部优化问题可以在本地并行解决，以优化全局成本函数。然而，大多数分布式优化技术需要假设每个计算都是同步的。在本文中，我们提出了一种异步通信的分布式优化算法。然后，我们通过模拟系统来将同步算法和异步算法与集中式算法进行比较，以找出计算时间和成本。
We consider an optimal power dispatch problem for a power grid including power generators and batteries as well as demand. Since the grid can be quite large we look at optimizing this grid in a distributed manner, where each local optimization problem can be solved locally in parallel in order to optimize the global cost function. However, most distributed optimization techniques need to assume that every calculation is synchronized. In this paper, we propose a distributed optimization algorithm with asynchronous communication. We then compare both synchronous and asynchronous algorithms with the centralized algorithm by simulating a system to find the calculation time and cost.
