Dynamic Performances of Split-Shaft Microturbine Generator (MTG) and Diesel Generator as Distributed Energy Resources

Abstract: This paper presents the dynamic analysis of load following performances of split-shaft microturbine generator (MTG) and Diesel Generator systems considering P-I type load following and P-I type speed controllers under stand-alone mode of operation. In this paper microturbine system coupled with a synchronous generator (SG) is considered. The dynamic performances of split-shaft MTG and Diesel Generator system are also examined when they are connected together to satisfy the load demand. Finally, the MTG and diesel generator systems are connected to an 11 kV rural distribution network to examine the transient behaviour during active power injection. Simulation result for all the cases are analyzed and presented in this paper.
