A Flexible Two Stage Weakly Meshed Load Flow using Multi-Port Compensation Technique

A two-staged load flow algorithm is proposed to solve a meshed distribution network by implementing a balanced fast and flexible radial power flow (BFFRPF) method. Firstly, a meshed distribution network is converted to a radial network by breaking the loops and the load flow of that radial network is done to obtain the open circuit breakpoint voltage. Then, the breakpoint currents are calculated using breakpoint impedance matrix. Secondly, breakpoint currents are injected into the radial network and the load flow is carried out again. In this way we can obtain the results of the original meshed network. The proposed load flow algorithm is validated using a 6-bus and IEEE 33-bus weakly meshed systems.
