This paper presents a load flow method for electricity distribution system called AC Linearized Flow Power (LACLF). The method is based on the AC Load Flow (ACLF) which are held in the linearization equations of the Jacobian matrix. Unlike ACLF algorithm, this method does not require an iterative process, which results in a fast and robust method. The LACLF considers all the coupling ACLF, including the coupling of active power with the magnitude of voltage and reactive power coupling with the phase angle, different from the traditional DC load flow method (DCLF).
The method is suitable for contingency studies and can be used when solutions quick, robust and repeatedly are requested. The big advantage is that the method is not iterative and offers solutions even where traditional ACLF diverges and more accurately than the DCLF. The method was applied to the distribution systems 34, 70 and 126 bars and applied to the transmission systems 14, 30 and 118 bars. The partial results of the tests demonstrate the effectiveness of the methodology.
The proposed methodology will be developed in Matlab® environment and tested in different distribution systems with various loading levels. The solutions will be compared with the load flow methods AC and DC. Initially we will use the Newton-Raphson, to compare the methods.
