Political Cycles, Electricity Policy, and Mexico's Economy
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

宽频振荡紧急控制是保障风电系统安全运行的“兜底”措施之一。由于风电系统非线性强度大及运行工况多变,难以建立宽频振荡在线风险评估的解析模型。为此,提出了基于数据驱动的宽频振荡风险在线评估方法及紧急控制策略。首先,设计了能够应对宽频振荡多模态和时变特征的宽频相量检测算法,为后续宽频振荡特征评估提供数据支撑;其次,利用最大李雅普诺夫指数作为宽频振荡动态演化趋势的量化指标,并根据风电机组模态阻抗的负电阻效应在线辨识宽频振荡源;然后,融合宽频振荡特征辨识结果,提出宽频振荡风险在线评估策略 ...
