Three-phase power flow for FRIENDS network

A new three-phase power flow calculation method is developed. The Gauss Seidel method is employed to calculate three-phase power flow. The methods can take the connection of a number of single-phase distributed generators into account and can handle loop systems. An algorithm of a new three-phase power flow calculation is introduced, and numerical examples are shown for a FRIENDS (flexible reliable and intelligent electrical energy delivery system) network, which has single-phase DGs and many loops.
