Performances Analysis of a Micro-Grid Connected Multi-Renewable Energy Sources System Associated with Hydrogen Storage

“…The water electrolyzer description is presented in [3,5,6]. The U(I) electrolyzer model characteristics used in this study at different cell temperatures are shown in Figure 10.…”

“…In the case these RESs are based on WTs or PVs, then Energy Storage Systems (ESSs) are necessary to further mitigate the effects of the seasonal and daily randomness fluctuations in the climatic (solar radiation, wind speed, temperature) and geographical conditions as well as the profiles of the required power. In addition, to maintain the power and energy balance as well as to improve the output power quality [2][3][4][5][6].…”

“…Knowing that the energy storage system as battery banks (BBs) is very important for the efficient and economical utilization of the MG system [25]. However, the lifetime of these systems decreases according to their operating modes, particularly according charge and discharge cycles [5,6,37]. To improve the energy supply reliability of WTs and PVs hybrid system, a fuel cell (FC) can be combined with an electrolyzer system, thus constituting a third energy source, to ensure the need for any additional, backups or supply power system [26].…”

“…Indeed, the DFIG driven by wind turbine (WT-DFIG) brings more benefits to the wind energy conversion system such as direct access on the AC grid, the reactive power compensation unit is not needed, the ability of opertating at three modes (sub, super and synchronous mode including the over-speed mode), the capability of producing electric power more than the rated power and a flexible active and reactive power control. Furthermore, the size of the AC/AC frequency converter with its DC-bus capacitor, the rotor side controller, the converter costs and power losses are reduced [2][3][4][5][6].…”

“…In the aim to develop efficient and economical wind energy conversion systems, different algorithm control applied to WT-DFIG have been proposed in the literature . Conventional control strategies are generally based on two most families, which are; the direct control techniques namely the direct torque control or the direct power control (DPC) [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], and indirect control strategies based on field-oriented control (FOC) [17][18][19][20][21][22][23]. In this case, we have the FOC Linear Vector Control (FOC-LVC) methods [17,18] and the FOC non-linear Vector Control (FOC-NLVC) [19][20][21][22][23], which are have been widely applied to WT-DFIG in differents operating quadrants and modes in many research works.…”
