This paper presents a novel hybrid intelligent algorithm based on the wavelet transform (WT) and fuzzy ARTMAP (FA) network for forecasting the power output of a wind farm utilizing meteorological information such as wind speed, wind direction, and temperature. The prediction capability of the proposed hybrid WT+FA model is demonstrated by an extensive comparison with a benchmark persistence method,...
In this paper, frequency control performance in a PV-diesel hybrid system is improved by using an energy storage system (ESS) with a virtual inertia controller. Simulation results show that the proposed method is feasible to reduce the frequency deviations and delivers maximum power compared to a fuzzy logic controller based method.
A hybrid power source consisting of electric double layer capacitor (EDLC) and battery is proposed. The charge and discharge control in this power source is executed so as to reduce the repetitive charge and discharge operation of battery. This operation contributes the life extension of battery. In addition, a buck-boost converter which prevents DC-link voltage from changing by the decrease of EDLC...
System security in the generation market is one of the important aspects in power system operation under deregulated environment. It becomes more crucial when thermal power system is integrated with wind system. This paper presents an approach to determine the security constrained unit commitment (SCUC) for thermal units integrated with wind power system. A Lagrangian relaxation based algorithm with...
