| description | Global warming has accelerated the transition towards clean and renewable energy (RE) resources. However, the intermittent nature of these resources presents challenges to their effective integration into power systems. A practical and sustainable solution involves storing the generated energy in energy storage systems (ESS) or converting it into renewable fuels and chemicals through power-to-x (PtX) processes. The latter has gained increased attention because of its ability to stabilize energy systems over extended periods. The application of PtX enables decarbonization of sectors in which direct electrification is challenging. PtX microgrids (MG) can operate in either grid-connected/on-grid or islanded/off-grid modes. Each operation mode requires specific equipment and strategies to ensure the power balance, stability, and resilience within the power system. Choosing the optimal operational mode for a PtX MG can be complex, because the on-grid and off-grid configurations differ significantly in terms of both technical performance and financial viability. Therefore, this paper presents a techno-commercial comparative assessment of a real industrial RE-based PtX MG, focusing on hydrogen (H2) production plants, under both operational modes. First, the essential components of the PtX MG and additional equipment required for each mode are introduced. Second, financial analysis evaluates the contribution of various equipment costs to the total equipment cost. Finally, the steady-state and transient performances of the on-grid and off-grid PtX MG are compared. These include load flow analysis (LFA), short circuit analysis (SCA), harmonic flow analysis (HFA), and low-voltage ride-through (LVRT) simulations. The PtX MG power system is modeled using PowerFactory software. |
