Hybrid power systems are increasingly considered in order to produce more electrical energy by renewable sources. Energy management of these plants is a challenge and in this paper we propose a new forecasting method for renewable sources an load demand to obtain an improved management. The novelty of this approach is that the proposed wavelet recurrent neural network, WRNN performs the prediction...
Renewable energy power generation systems are promising energy sources where hybrid solutions such as Photo Voltaic-Wind Turbine (PV/WT) grid connected power systems are largely adopted for their good potentials. Design of such systems requires that particular attention must be paid to an optimal combination between the two different power sources because of the complex nature of several affecting...
The proposed dual input hybrid buck L/hybrid buck C (HBLC) DC-DC converter, suitable to be used in renewable energy, telecom, automotive applications, etc., consists of two hybrid step down converters with a high ratio of the input/output voltage, connected to a single output. Operation modes, analytical description and digital simulations, validated by experimental results, are presented in the paper.
The increasing attention on energy autonomous sensing and computing systems which can operate unattended tens of years, have made energy harvesting and power conversion techniques key technologies for the future. The goal is to power systems nearly perpetually if the scavenger is exposed to reasonable environmental energy conditions. However, the system is still threatened to run out of energy, if...
This paper presents a sizing method and supervisory control for the suitable energy management of a stand-alone hybrid system with photovoltaic (PV) solar panels, hydrogen subsystem and battery. The battery and hydrogen subsystem, composed of fuel cell (FC), electrolyzer and hydrogen storage tank, act as energy storage and support system. A sizing method based on Simulink Design Optimization (SDO)...
Dynamic performances of a hybrid wind turbine generating system consisting of series connected plural wind generators, a current-source thyristor inverter, a synchronous generator driven by a prime mover, and a duplex reactor are discussed. It is shown that tip speed ratios of the individual turbine and the system output power can be controlled almost constant with the proposed method, making an effective...
