In this paper, we address parameter estimation for hybrid dynamical systems with statedependent events and time-delayed parametric switching. Parameter estimation of hybrid systems can aid in system identification, model refinement, and contingency and stability analysis in various fields, including chemical, electrical, and power systems engineering. We discuss parameter estimation for hybrid ...

As is well known, estimating parameters of the tree-parameter weibull distribution is a complicated task and sometimes contentious area with several methods vying for recognition. Weibull distribution involves in reliability studies frequently and has many applications in engineering. However estimating the parameters of Weibull distribution is crucial in classical ways. This distribution has t...

the forecasting of hydrological variables, such as streamflow, plays an important role in water resource planning and management. recently, the development of stochastic models is regarded as a major step for this purpose. streamflow forecasting using the arima model can be conducted when unknown parameters are estimated correctly because parameter estimation is one of the crucial steps in mode...

Estimating the fundamental frequency and harmonic parameters is basic for signal modelling in a power supply system. Differing from the existing parameter estimation algorithms either in power quality monitoring or in harmonic compensation, the proposed algorithm enables a simultaneous estimation of the fundamental frequency, the amplitudes and phases of harmonic waves. A pure sinusoid is obtai...

This paper describes a power system inertia estimation method that utilizes perturbations caused by the flow switch on an HVDC interconnector. The analysis is performed using real measurements from Ireland's all-island system. employs energy based technique which permits non-step change to be used for calculation and encapsulates challenges associated with use of data. While it shown synchronou...
