Mixed Method For Transmission Loss Allocation

The paper presents a method for transmission loss allocation developed as a mix of Zbus transmission cost allocation method and power summation method for loss allocation. Zbus method is used to decompose the power flows through the branches in the system and power summation method with allocation of crossed terms of active and reactive power is used for branches losses allocation. This is the reason why method is called mixed method. The method is tested on real data individual model of power system of North Macedonia for future planning purposes The model is with high presence of renewables (PV and WIND). The results are presented and discussed.
