With the wide application of flexible AC transmission system (FACTS) in power system, one of the major directions of FACTS development is the research of multi-FACTS coordinated control based on wide-area measurement system (WAMS). In this study, the wide area centralized coordination control architecture is established. Based on the structure of the dynamic output feedback control and the theory...
This paper presents a novel approach for estimating mode shape for participation (MSFP) among areas or main power plants involving inter-area oscillation (IAO) mode, by analyzing power deviation (ΔP) signals. The case study has been carried out on a planning case in East China Power Grid (ECPG). The results indicate that the proposed algorithm is effective, and imply its potential applicability in...
This paper proposed a new algorithm to perform the online determination of the low frequency oscillation modes in large interconnected power system. First, the generator's active power and its speed deviation were represented in the form of generalized phasor and the relationship between their phase angles was deduced. Then a simple system was constructed to illustrate the correspondence between the...
An entanglement control strategy is presented for two-qubit quantum systems against Markovian noises. This proposal is realized by a tunable coupling between qubits which is induced by varying the parameters of an intermediate squeezed field. Its applications to the independent and collective amplitude damping decoherence channels and their mixture show that entanglement can be efficiently enhanced.
