摘要
将大系统理论与新能源电力系统相结合,是解决当前"双侧随机"问题、实现系统"源?网?荷?储"协调优化的关键手段之一。首先给出了大系统的特点与大系统理论的基本内容,分析了大系统理论与新能源电力系统的兼容性;概述了大系统控制论的基本内容,从广义模型化、大系统分析及大系统综合3个方面提出了新能源电力大系统多级递阶优化控制的主要框架;给出了实现新能源电力大系统优化控制的关键技术。
The combination between large scale systems theory and alternate electrical power systems will be the key to solve ＂bilateral randomness＂ problem and realize the coordination between ＂generation-grid-load-energy storage＂. The characteristics of large scale systems and basic content of large scale systems theory were summarized at first. Meanwhile the content of large scale systems cybernetics was present, the basic structure of multilevel hierarchical optimal control for alternate electrical power large systems was derived from model generalization, large scale systems analysis and large scale systems comprehensiveness. At last the key technologies of the optimal control over alternate electrical power large systems were proposed.
