New Network Sensitivity-Based Approach for Real-Time Complex Power Flow Calculation

IET Generation, Transmission and Distribution, 2012
[[abstract]]This study proposes a novel network sensitivity-based approach to solving complex power flow calculation problems in real time. A new sensitivity factor, named Jacobian-based distribution factor (JBDF), is used for the calculation of active ...

An Approximate Power Flow Method to Deal with the Non-convergence Problem of Power Flow Calculation

2018 International Conference on Power System Technology (POWERCON), 2018
A new concept of approximate power flow (APF) is proposed in this paper, aiming to help deal with the non-convergence problem of power flow calculation. In the approximate power flow model, active and reactive power decoupling strategy is adopted, and a branch model with virtual midpoint is the key foundation of the whole research.

Calculation of power flow between coupled oscillators

Journal of Sound and Vibration, 1966
Abstract A perturbation method is developed for calculating the statistics of the energy transfer process between weakly coupled oscillators. The method is used to calculate first-order approximations for (a) the mean value, and (b) the spectral density of the power flow between two stiffness coupled oscillators under white noise random excitation ...

Accounting the Second Derivatives in the Power Flow Calculation

Advanced Materials Research, 2014
In this paper, it is show how the second derivatives of the Hessian matrix influence on the convergence of the power flow calculation. Convergence conditions of the Combined Newton’s method using 14 nodes IEEE testing schemes are investigated. The method can be used to determine the control actions to pull the operating point into the feasibility ...
