“…Nevertheless, in practise, electrodes overpotentials produce electrical efficiencies around 50%. However, the electrochemical reactions produced are exothermic, so the combined use of electricity and heat (cogeneration) produces a higher net efficiency (total efficiency could reach values around 80-85%) [6].…”

One of the most outstanding products of fuel cells is electrical power but, currently, there is a reduced number of publications that provide experimental data about the performance of fuel cells when used for supplying Alternating Current (AC) loads. Most of the existing publications provide experimental data only with direct current (DC) loads, or analyze the performance with AC loads using simulation models. For this reason, this paper analyses experimentally the behavior of a proton exchange membrane fuel cell (PEMFC) system when feeding different electrical loads. The system tested is constituted by a PEM fuel cell, a storage battery, electronic converters and electrical loads. In the tests, the fuel cell system supplies power to three different loads: DC, single‐phase AC and three‐phase AC. For these cases, voltage, current, power, power factor and efficiency data are shown, at different load levels. From those parameters, efficiency of the global system is estimated. Finally, as the power quality concept is a topic of increasing importance when supplying electricity, the total harmonic distortion (THD) of the electric signals has also been analyzed.

“…The storage equipment include sodium-sulfur battery, lithium battery, supercapacitor, flywheel, etc. [6], having a dynamic response time at the level of milliseconds, which is negligible in power coordination [6][7][8][9]. CS normally includes micro-turbines (MTs) and fuel cells (FCs).…”

A multi-agent system (MAS) provides flexible and intelligent control schemes for microgrids and their units. However, a certain period of time is required for a controllable source (CS) to change its output power, and the communication delay poses a challenge for real-time tracking of CS output power in MAS control, an important factor affecting the transient performance of MAS power coordination. In this paper, we propose and emulate a new power tracking method based on the communication inside MAS about the change of output variation speed in every CS together with a timestamp for each change. The MAS emulates and tracks the total output power of all CSs in real time. Compared to the conventional method, the emulation results indicate that this new method has a significantly better real-time performance, especially for a large number of CS and under more undesirable communication conditions.
