Modelling and Dynamic Stability Study of Interconnected System of Renewable Energy Sources and Grid for Rural Electrification

Abstract

AbstractThis paper presents modelling and dynamic stability study of an interconnected system of renewable energy sources (RES) and grid. The objective of this system is to utilize RES for providing continuous power to a cluster of villages having fixed feed of power supply from the grid. The renewable energy sources considered in the interconnected system are wind and biogas. Therefore, dynamic models for doubly fed induction generator (DFIG) and squirrel cage induction generator (SCIG) based wind energy conversion system have been developed for the proposed interconnected system. The static synchronous compensator (STATCOM) has also been employed to stabilize system voltage as per the requirement while, synchronous generator-based biogas genset has been used for system frequency and voltage regulation. The behavior of the proposed system has been analyzed under various load and input wind power disturbances.
