This paper describes the power system study required by Malaysian Sustainable Energy Development Authority (SEDA) prior to the Distributed Generation (DG) interconnection. A number of DG interconnection guideline and document are described. A case study is used to demonstrate the procedure of steady state analysis. Load flow analysis under steady state conditions and short circuit analysis are discussed. Lastly, the simulation results are presented.
This paper presents a guideline of determining impedance of transformer when conducting system study for renewable energy interconnection. The method can be used when there is lack of information on the transformer’s technical details. Simulation examples are presented to demonstrate the effect of impedance on the losses and short circuit current. The guidelines introduce in this paper will increase reliability and accuracy of the system study conducted by engineer and researchers in assessing the possible impact renewable energy integration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
