摘要

A novel hybrid Remote Area Power Supply (RAPS) system consisting of a Doubly Fed Induction Generator (DFIG) based wind turbine and a battery Energy Storage System (ESS) is investigated in this paper. The proposed RAPS system also consists of a dummy load and its controller. The battery energy storage system is used as a buffer which is connected to the DC link of the DFIG. The dummy load which is connected to the AC side of the system is used to absorb the energy associated with over generation, a situation which cannot be handled through the battery system. Control coordination of the dummy load and battery storage system helps maintain the system instantaneous power balance thus ensuring the regulation of the system frequency. The suitability of the proposed RAPS system is assessed in terms of the bandwidth of voltage regulation capability. Small signal model analysis although simpler to perform, is undertaken with a view to compare some of the corresponding results with those obtained using detailed models. Detailed modular simulation of the system is discussed in relation to the system voltage, frequency, DC link stability of the doubly fed induction generator and power sharing among different system components. The model of the entire system has been developed using SimPowerSystem toolbox in MATLAB.
