Power Flow Analysis Using Fuzzy Logic Methods in Electrical Systems Sulbagsel

Abstract

Analysis of power flow in an electric power system is an analysis that aims to determine the operating conditions of an electric power system. This study aims to implement fuzzy logic in power flow analysis with a case study of the electrical system of South Sulawesi (Sulbagsel). To achieve research objectives, Newton Raphson is used as a basis for managing fuzzy logic programs using MATLAB software. The implementation of fuzzy logic requires several stages, namely determining input and output, determining the membership-function, determining the rules base, the inference stage using the Mamdani method. Refers to the flow valuepower using the Newton Raphson method, the results show that fuzzy logic works well with an average MAPE power loss value of 4.134%. Computation time with fuzzy logic is 136.3660 ms while the Newton Raphson methodtook 192.9577 ms.
