The proposed system integrates photovoltaic (PV) sources directly with an electrolyser stack, thereby eliminating the need for traditional power converters. With the removal of traditional power converters, maximum power point tracking is achieved through dynamic switching of electrolyser cells in the stack, enabling load variation to maintain optimal voltage for maximum power output. The demonstration methodology involves comprehensive MATLAB Simulink analysis of the integrated system performance through controlled PV-electrolyser interactions.

Analytical & State-Space Control Methodology

For years, photovoltaic (PV) arrays have been widely utilised in the renewable energy sector to capture sunlight and convert it into usable energy, such as for generating hydrogen. Depending on various factors, a PV array has an optimal output point known as the maximum power point (MPP). To precisely find this point, several MPP tracking (MPPT) algorithms have been devised . One widely used algorithm is the perturb and observe method, which involves making small adjustments to the array’s operating point to locate the MPP . Another approach, known as the hill climbing method, employs a different strategy to achieve the same goal, by iteratively adjusting the operating point to move towards the steepest point of the power-voltage curve. These MPPT techniques are instrumental in maximising the energy output from PV arrays .

Simulink Waveforms & Power Quality Findings

Traditionally, MPPT is achieved by regulating the PV array voltage irrespective of the load voltage. This necessity drives the utilisation of power converters. However, a power converter ultimately leads to significant energy losses and increased costs. function involves the separation of hydrogen and oxygen from water molecules. The extracted hydrogen can then be used as a green fuel . Large renewable energy projects have integrated electrolysers, with the aim of extracting hydrogen to drive future power systems, such as in industries and hybrid transportation , , , . Electrolysers are often coupled with renewables to store excess renewable power when renewable energy production is abundant. The hydrogen can then be used during periods of low renewable generation, to meet network demands. Typically, electrolysers function within a voltage range of 1.5-2 V , . To achieve higher voltage and power levels, electrolysers are arranged in a stack , .
