In this paper we address the problem of frequency stability in unit commitment (UC) optimisation process. We include a set appropriately defined constraints UC formulation for operational planning scenarios advance real-time operation. Consequently, cover system against loss largest infeed under N−1 security criterion.The main contribution our work consists using method separable programming to...

A method is presented to analyze the stability of feedback systems with neural network controllers. Two theorems are given prove asymptotic and compute an ellipsoidal innerapproximation region attraction (ROA). The first theorem addresses linear time-invariant systems, merges Lyapunov theory local (sector) quadratic constraints bound nonlinear activation functions in network. second allows syst...

The problem of control of nonlinear process systems subject to input constraints and sensor faults (complete failure or intermittent unavailability of measurements) is considered. A fault-tolerant controller is designed that utilizes reconfiguration (switching to an alternate control configuration) in a way that accounts for the process nonlinearity, the presence of constraints and the occurren...
