Effects of Front-end Converter and DC-link of a Utility-scale PV Energy System on Dynamic Stability of a Power System - 2017 PROJECT TITLE :Effects of Front-end Converter and DC-link of a Utility-scale PV Energy System on Dynamic Stability of a Power System - 2017ABSTRACT:This paper presents a technique for small-signal dynamic studies of Power Systems including utility-scale PV energy systems considering the effects of dc-facet components. Existing methods commonly model a PV energy system as a dc supply connected to a grid-tied inverter. This paper shows that the dc parts of a PV energy system can additionally contribute in the dynamics of the ability system in the range of little-signal studies. The paper initial develops the model of a PV energy system by merging the submodels of dc-and ac-aspect components. Then, a method to get the augmented model of the facility system including a PV energy system can be explained using a study system. The study system consists of a PV energy system in parallel with a synchronous generator connected to a grid. Then, primarily based on eigenvalue analysis, verified by time-domain simulations, it's shown that the dc-link capacitor, front-end converter, and its controller will introduce oscillatory modes in subsynchronous vary of frequencies. Furthermore, it's shown that the damping of the sensitive modes will significantly vary with respect to the parameters of the dc-side elements. Did you like this research project?
