In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...

in this paper a new algorithm based on phasor measurements for estimating the thévenin equivalent (te) and system inertia constant is proposed. the method estimates the network te seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at phasor data concentrator (pdc) center. it is shown that the parameters of the te could be estimated at...

On-chip memories are one of the most power hungry components of today’s system on a chips (SoCs). The on-chip memories generally use higher supply (Vdd) and threshold (Vth) voltages than those of logic parts to suppress the static power consumption without increasing the access delay of the memories. This design policy, however, increases the dynamic power consumption since the dynamic power co...

This paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. The hybrid DC power sources are connected to grid using power electronic converters include DC-DC converter and grid connected voltage source inverter. The power from hybrid power sources is controlled during voltage sag by designing of control strategy for DC-DC converter....

One of the main actions required to face and limit global warming is substitution conventional fossil-fueled electrical generators with renewable ones. Thus, it becomes fundamental create non-dispatchable able provide services for power system stabilization that nowadays are delivered by Particularly, usually connected through electronic converters lacking natural responses frequency variations...

The electrical grid is evolving from a network consisting of mostly synchronous machines to mixture machines, and inverter-based resources such as wind, solar, energy storage. This transformation has led decrease in mechanical inertia, which necessitate need for the new provide frequency responses through their inverter interfaces. In this paper we proposed strategy based on model predictive co...
