Abstract

The main purpose of this paper is to analyze the sequential power flow of an autonomous microgrid (MG) with various distributed energy resources (DERs). This system consists of five different types of DERs and loads. These DERs include two 1.5 MW diesel engine generators, two 1.79 MW gas turbine generators, two 1.0 MW fuel cell generation systems, a 1.5 MW wind turbine generator, and a 0.5 MW photovoltaic generation system. In this paper, based on the Newton-Raphson method, a sequential power flow program was developed in Matlab environment and its accuracy is verified. And the program was used to simulate and analyze the daily power flow of the MG under the autonomous operating mode. The simulation results demonstrate that the developed approach is suitable for the daily power flow analysis of the autonomous MGs.
