This paper aims to study the stability and stabilization of a class of discrete-time Markov jump singular systems with general uncertain transition rates. Sufficient conditions are proposed for the stochastic admissibility by using linear matrix inequalities (LMIs), a sufficient condition is given to ensure the existence of a state feedback controller and an output feedback controller under the condition...
Power system islanding is the last defense in protecting power grids from wide-area blackout. The operation of an island power system differs in many ways from that of large interconnected networks. The research frequency is important significance to improve the security and reliability of the isolated power grid. The characteristics of islanding operation are introduced in this paper; the control...
Ac system strength indicated by short circuit ratio (SCR) and its impact on commutation failure in HVDC transmission system are studied. SCR is varying along with ac system operation mode, grid configuration, load characteristics and reactive power compensation devices at inverter station. Quasi-steady state calculations show that SCR increases commutation reactance and consequently increases the...
