Vo ltage stability is one o f the key issue s in the o pe ratio n o f mode rn po we r syste ms. M any e mergenc y contro ls have bee n carried out to prevent vo ltage co llapse . In this pape r, a hybrid method is pro posed fo r power syste m emergenc y co ntro l to coo rdinate seco ndary vo ltage co ntro l and load-shedding. T he pro po sed hybrid technique consists o f two laye rs: the lo we r laye r is the local co ntinuo us-time contro lle rs, while the higher laye r is the supervisory o ne drive n by the disc re te-e vents to coo rdinate the low-le vel co ntro lle rs. In this paper, the co nce pt o f hybrid syste m is introduced rst. T hen the imple mentatio n o f a hybrid method for the e mergency co ntro l is described. Simulatio n re sults o n the data o f a real syste m verify the e OE ec tive ness of the pro po sed hybrid contro l methodo logy.

“…Analysis and control of nonlinear phenomena in hybrid dynamical systems are practically significant for industrial applications such as process control [30,31], mechanical systems [32], robotic control [33], power systems [34], and power electronics [35,36]. A number of methodologies have been developed for analysis and control design of hybrid (piecewise smooth) dynamical systems [37].…”

“…The need to enhance the efficiency level, to increase the profitability as well as the commitment to meet precise production standards has motivated the development of automatic systems of rising complexity. In the oil industries context in addition to the above motivations, the requirement to operate plants in high safety conditions calls for the introduction of automatic controlled systems ( [3], [10], [11]) at the various level of control hierarchy.…”

In this paper hybrid automata have been used in order to identify the more suitable model of a gasification process, at the occurrence of variations of plant's operative conditions and specifications. From the identification process performed on historical series at disposal and from the model validation phase it was concluded that one single model was not sufficient to assure good predictions, especially in the case of large prediction horizons. This called, from a methodological point of view for the application of a hybrid model, in particular of hybrid automata in order to guarantee best performances in the choice of the best model. Performances of the proposed hybrid model are discussed and compared with the ones obtained with a fuzzy supervisor based on the same linear models.
