Methods for Power Flow Analysis

  • Marko Čepin
Chapter

Abstract

The methods for power flow analysis can be divided to deterministic and probabilistic methods. The deterministic methods, such as Newton?Raphson method, Gauss?Seidel method, fast decoupled load flow method, and direct current load flow method, use specific values of power generations and load demands of a selected network configuration to calculate system states and power flows. The probabilistic methods require inputs with probability density function to obtain system states and power flows in terms of probability density function, so that the system uncertainties can be included and reflected in the results. The methods are presented and the related equations and systems of equations are explained. The focus is placed to the Newton?Raphson method and to Gauss?Seidel method. The iterative procedures are explained. The graphical representation of the procedure steps is given.
