Abstract
- Magnetic materials have become more and more user friendly in recent days particularly in an electronic based infrastructure. The study proposes a direct drive permanent magnet based Synchronous Generator as Tidal turbine in a hybrid tidal wave energy conversion system (TWECS) and discusses its performance for better stability. The objective of the study is to analyse the role of permanent magnet based generator in TWECS for overall improvement of stability through reactive power management. The isolated TWECS becomes unstable either by random load variations or by non uniform wind and tidal power inputs. Consequently the overall stability of the TWECS is brought to stable and normal stage by the control of reactive power with the inclusion of the custom power based devices. In addition to the effects of permanent magnet in case of DDPMSG for improving the overall system stability, optimisation tools like PSO, GSA and PSOGSA are added for further improvement in system performance. • Small signal modelling of DDPMSG based Micro grid has been implemented. • UPFC controller addresses the Reactive power compensation and stability issues of the Micro grid. • Comparison between DDPMSG and DFIG based systems are carried out with variable load and wind power inputs. • Stability analysis with nyquist, popov, Nichols are carried out. • Overall stability of the system is studied with Eigen values, participation factors.
