This paper presents a frequency-based approach energy management in an Electrical Hybrid Boat (EHB) application. An association of a variable speed DieselPermanent Magnet Generator (Diesel-PMG) with a supercapacitor and a battery bank is proposed to satisfy energetic demand of EHB. The supercapacitor and the battery bank are connected to DC-link via bidirectional DC/DC converters, while the variable...
This paper proposes the hybrid energy system control strategy considering the State of Charge (SOC) of battery and the fuel consumption of diesel generator. The hybrid energy system is composed of diesel generator, PV unit, and Energy Storage System (ESS) with battery and supercapacitor. To optimize the fuel consumption of diesel generator it should be operating at the rated power based on the BSFC...
This paper proposes the hybrid energy system for a smart green building. The hybrid energy system has the variety of power sources, such as photovoltaic generation systems, wind power generation systems, and diesel generator with energy storage systems. The energy storage system can be combined the battery and super-capacitor, and it can be optimized for the fuel consumption efficiency of the diesel...
In this paper, strategies of short and long term fluctuations mitigation are applied to a wind-diesel hybrid system. Ultracapacitors (UC) and batteries are operated in a complementary mode. The DC-bus voltage is maintained at a constant value by the diesel engine while providing a smoothed current. The proposed strategies are based on the wind power frequencies distribution between the storage devices...
This paper deals a new strategy for wind-diesel hybrid system energy improvement using Ultracapacitors (UC) and Battery. Energy management strategies are focused on the frequencies distribution of the wind generator current between UC and Battery. The developed control laws are based on the knowledge of the dynamic behavior of each source, in aim to prevent the diesel generator against the fluctuating...
