Renewable Energy Integration In Unbalanced Three Phase Power Flow using Gauss-Seidel and Newton-Raphson Methods

This paper presents the solution of three phases power flow in unbalanced electrical network. The main objective of the three flow analysis of power is to calculate the active and reactive powers flowing in each phase with the magnitude and the angle of the voltage at each bus of the system for the specific loading conditions. In this work, the negative- and zero-sequence components are presented using nodal voltage equations. The three phase power flow is formulated and solved by using Gauss-Seidel and Newton-Raphson methods and has been tested using IEEE 5 bus system. The wind power in this work represented by wind electric system which made up of a wind turbine mounted on a tower to provide better access to stronger winds, after that, we inject wind power generator to show the effect of the wind energy in the power flow for unbalanced electrical power system. The solar unit is considered in this work by adding two energy types in one bus.
