With large-scale wind farms connected to AC/DC network, the transient stability assessment (TSA) of power system becomes more and difficult. Among them, estimating region attraction (ROA) equilibrium point is a traditional but still challenging problem. Based on Lyapunov theory, this paper proposes new approach obtain enlarged estimation ROA. The optimization updating strategy shape function in...

A synchronous generator may sometimes be able to withstand a large impact but it may fail to retain synchronism under a small impact due to growing oscillations, leading to instability. This is called dynamic instability. It occurs for specific operating conditions and network configurations, particularly in presence of fastacting excitation control. The paper presents techniques of small signa...

This paper conducts a fundamental analysis on the induction generator infinite bus system which is a useful representation for a wind energy converter interfaced to a utility through a transmission line. A third order dynamic model is used to represent the induction generator and the resultant nonlinear system equations are analyzed to derive a condition that guarantees the existence of equilib...

Modern high-end machines feature multiple processor packages, each of which contains multiple independent cores and integrated memory controllers connected directly to dedicated physical RAM. These packages are connected via a shared bus, creating a system with a heterogeneous memory hierarchy. Since this shared bus has less bandwidth than the sum of the links to memory, aggregate memory bandwi...
