“…Due to the slow dynamics of the FC system, the auxiliary power source of the lead-acid battery has been used for use in DGs. In order to use this hybrid system, an algorithm was presented that describes how to supply the load and charge and discharge the battery [9,10]. In this algorithm, if the power required by the load is less than the power produced by the FC, then the entire load is supplied by the FC.…”

“…Therefore, in this reference, by adding a FC scattered production source, providing heat loads is also It has been considered and in addition to considering controllers and previous optimization goals, fuel costs have also been considered. In this comprehensive control method, in addition to the control variables related to the devices used in the network, the production power of resources is also used as a control variable to reduce costs and pollution [9,12].…”

In this paper, the use of a FC system connected to the network is proposed as a source of DG with high reliability, and for this purpose, the dynamic model of the fuel cell has been simulated. A hybrid system of fuel cell distributed generation (FCDG) is presented to provide electrical energy for a small isolated area. Boost converter (DC/DC), in order to increase the voltage level of the system and stabilize the DC link voltage has been used, which provides the possibility of connecting several different scattered production sources in parallel. Voltage stability is concerned with the ability of a power system to maintain acceptable bus voltages under normal conditions and after being subjected to a disturbance. The use of DG sources has many advantages, including meeting peak load needs, reducing network losses, providing reactive power locally, and regulating network voltage. Among all sources of distributed production, fuel cells are of special importance due to their high efficiency, high energy density, the ability to simultaneously produce heat and electric power, and low emission of pollutants. Using fuel cells (FCs) have several advantages and in this paper we investigate the effects of FCs on power systems via simulation a single machine (DG as small gas turbine coupled with a FC) in the Dig Silent area for different PF of FC. Different PF for FC obtained with control the DC to AC inverter. We found that by control the PF of FCs, we can increase the limitation of reactive generation of overall system and improve the V-P V-Q characteristics of overall system. With the grid-connected inverter's switching control, the active and reactive power injected into the grid is controlled independently.
