Soft-error resiliency of power flow calculations
2017 52nd International Universities Power Engineering Conference (UPEC), 2017This paper develops a model to show the effects of soft errors on power flow calculations. We create artificial bit-flips and apply them to solve linear equations obtained in Fast Decoupled Load Flow (FDLF) method. With this, we aim to represent the sensitivity of FDLF iteration against soft errors with a statistical view by using different numerical ...

Сombined Newton’s Method for Power Flow Calculation
Power and Energy Systems, 2013In this paper, it is shown how the full 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. It is shown, that the method allows getting solution when the initial data are incompatibles, and operating point is outside the ...

Power Flow Calculation Method of DC grid with Interline DC Power Flow Controller (IDCPFC)
2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2019In recent years, flexible HVDC transmission technology gradually matures currently, which can not only achieve large capacity and long distance transmission, but also can maximize the use of renewable energy. However, the DC grid has less degrees of freedom than AC grid which restricts its power flow control ability.
