Over-limit risk assessment method of integrated energy system considering source-load correlation
Global Energy Interconnection, 2023 In an integrated energy system, source-load multiple uncertainties and correlations lead to an over-limit risk in operating state, including voltage, temperature, and pressure over-limit. Therefore, efficient probabilistic energy flow calculation methods

Using Largest Lyapunov Exponent to Confirm the Intrinsic Stability of Boiling Water Reactors
Nuclear Engineering and Technology, 2016 The aim of this paper is the study of instability state of boiling water reactors with a method based in largest Lyapunov exponents (LLEs). Detecting the presence of chaos in a dynamical system is an important problem that is solved by measuring the LLE.

Mitigation of subsynchronous control interaction in DFIGs using active disturbance rejection control
IET Generation, Transmission & Distribution, 2021 Recently, a new type of subsynchronous oscillation (SSO) has occurred in doubly‐fed induction generator (DFIG)‐based wind farms. This oscillation is also called the subsynchronous control interaction (SSCI), which is mainly caused by the interaction ...

Chaos in a nonlinear Lorentz-Lu-Chen system via the fractal fractional operator of Atangana-Baleanu
Interciencia, 2023 This paper establishes the presence or absence of chaotic behaviors in the nonlinear modified Lorentz-L\\\"{u}-Chen using the Atangana-Baleanu fractal-fractional operators. Moreover, we investigate the impact of the fractal-fractional operators on the system\'s behavior and provide insights into the underlying dynamics.

Chaotic behaviors of stable second-order digital filters with two’s complement arithmetic [PDF]
, 2003 In this paper, the behaviors of stable second-order digital filters with two’s complement arithmetic are investigated. It is found that even though the poles are inside the unit circle and the trajectory converges to a fixed point on the phase plane ...

Chance-Constrained AC Optimal Power Flow: A Polynomial Chaos Approach [PDF]
IEEE Transactions on Power Systems, 2019 As the share of renewables in the grid increases, the operation of power systems becomes more challenging. The present paper proposes a method to formulate and solve chance-constrained optimal power flow while explicitly considering the full nonlinear ac
