Electricity loads in buildings are increasingly supplied by distributed renewable generation sources such as photovoltaic (PV) modules or fuel cells. Often these systems are combined with an electricity storage to raise the level of self-consumption in buildings and to reduce the load on the electric grid. PV production and battery storage are both inherently based on direct current (DC) power....

Modular Battery Energy Storage systems (MBESSs) enable the use of lower-rated voltage converters and battery modules, simpler management systems. They also improve system's reliability allow flexible power sharing amongst different modules. This paper proposes a power-sharing algorithm which maximizes energy conversion efficiency this storage system, considering state charge (SoC) balancing lif...

This paper presents a mixed-integer linear programming (MILP) formulation for sizing and siting of battery energy storage systems (BESSs). The problem seeks to minimize both operation costs BESS investment. proposed model includes restrictions the conventional security-constrained unit commitment problem, piece-wise approximation power losses, hydro generation units. is tested in 6-bus test sys...

In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...
