Using quadratic programming for power flow calculations
2010 Conference Proceedings IPEC, 2010This paper presents a simple, reliable and efficient method for practical applications of power flow calculation with/without slack bus. The proposed technique is attractive both for interconnected and islanded power networks where the definition of “slack bus” may be meaningless.

Study on Power Flow Calculation Using PSASP
Applied Mechanics and Materials, 2014The power flow calculation is a basic electrical calculation which is to study the steady state operation of power system. Its task is to decide the whole system running state according to the given operating conditions and the network structure. The power flow calculation is the basis of the stability calculation and fault analysis of power system. In

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 ...

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 ...
