摘要
微分平坦理论的非线性控制策略能够完整地描述系统的状态轨迹,提供良好的系统动态特性。为此,对微分平坦理论的基本概念、研究现状、控制系统实现方式进行了详细描述,并从微分平坦系统的构造、基于轨迹生成和轨迹跟踪的微分平坦系统设计实现及自动发电系统微分平坦控制架构几方面阐述了其在自动发电控制AGC(automatic generation control)中的应用。研究表明,基于微分平坦理论的AGC控制策略是有效的、适用的,相比于传统的AGC控制策略,其从系统的全局优化角度出发,能够显著提高电网新能源消纳能力,有效保证系统的频率质量。
As a new nonlinear control strategy, flatness based control attracts widely attention because it can provide preferable system dynamic response by fully describing the state trajectory of system.This paper proposes the basic con- cept and implementation method of the differential flatness theory in automatic generation control （AGC）, which em- phasizes on the application of differential flatness theory in AGC with the details of derivation and implementation of the flatness based AGC model, system construction based on trajectory generation and trajectory tracking and the flatness based AGC framework. Results indicate that the flatness based AGC can significantly enhance the new energy consumptive capability and guarantee the frequency quality of power system from a global optimization perspective.
