带有储能设备的智能电网电能迭代自适应动态规划最优控制

摘要

The smart grid is a new generation of power grids, and also the common choice of the international power industry. This paper aims to establish a new adaptive optimal control theory and a set of methods based on adaptive dynamic programming (ADP) for a smart grid with energy storage devices. The intelligent interactions between the power generation side and the clients can be finally achieved to create a new way of optimal matching of the supply and demand for the smart grid. First, the optimality principle of dynamic programming for the grid with energy storage devices is given, and optimization objective is then presented. Then a new iterative adaptive dynamic programming method is developed to achieve the optimal control of energy storage devices, and convergence of the adaptive dynamic programming method is also proved. Finally, a simulation example is given to show the effectiveness of the method.%智能电网是新一代电网建设的目标,也是国际电力工业界的共同选择。本文研究在储能设备接入电网情况下,建立一套基于自适应动态规划(Adaptive dynamic programming, ADP)的智能电网电能自适应优化控制的理论与方法,实现电网发电端以及用户端的智能交互,开辟对智能电网供需优化匹配与调控方法的新途径。论文首先给出动态规划的最优性原理以及带有储能设备智能电网的运行方式并提出优化目标；然后,设计新型迭代自适应动态规划方法实现对储能设备的最优控制,并证明自适应动态规划方法的收敛性,在理论上保证了对智能电网电能的优化；最后,给出仿真例子显示出所提出控制方法的有效性。
