This paper presents different works which are actually developed in the field of fuel-cell hybrid systems in different public laboratories in France. These works are presented in three sections corresponding to: 1. hybrid fuel cell/battery or supercapacitor power sources; 2. fuel-cell multi-stack power sources; 3. fuel cell in hybrid power systems for distributed generation. The presented works combine...
In this paper, a new control strategy is proposed to manage the electrical power of a hybrid trigeneration system composed of a concentrated photovoltaic and thermal captator, an electrical storage group (including lead acid batteries and supercapacitors), a genset and a lithium bromide absorption machine. The architecture is based on a double DC-bus configuration. An improved control management of...
A hybrid power system with a PV energy conversion system is proposed with lead-acid batteries based long-term storage units and ultracapacitors based fast-dynamic storage units in a DC-coupled structure. It is necessary and important to manage the powers among those different power sources. A power management algorithm is proposed for this hybrid power system by taking into account the characteristics...
A hybrid power system is proposed and is based on wind energy conversion system with hydrogen based long-term storage unit and super-capacitor based fast-dynamic storage unit. A power management algorithm is organized in different time scales for its normal operating mode. Four studied cases show that, the long-term storage can compensate or absorb the difference between the generated fluctuating...
