For the purpose of improving comprehensive performance including stability, security and economic benefit of power system, in this study a two-level hierarchical hybrid control is proposed in a real-time manner. First, a novel hybrid model is founded to clearly explain the hybrid dynamical behaviors of the power systems. On the basis of the model, a hybrid control scheme is designed in an interaction manner between the discrete control strategies at the upper level and the continuous dynamical controls at the lower level. The upper level discrete control strategies are responsible for converting operating modes to guarantee the security during significant disturbances and the economic benefit of overall system. After locating operating modes, the lower level local continuous controllers are responsible for regulating dynamic behavior of each controlled unit to obtain the satisfactory stability performance. The effectiveness of the proposed hybrid control is demonstrated through simulation examples.
