Enhancing Grid Stability in Eco-Industrial Parks Using Renewable Energy and Pumped Hydro Storage

There is still a lack of comprehensive research addressing the combined operation of renewable energies and energy storage technologies within grid-connected eco-industrial parks. This article addresses this gap by focusing on the modelling and analysis of an electrical network within an eco-industrial park connected to the national grid, integrating wind and photovoltaic power along with a pumped hydro storage system. The objective is to maximize demand coverage and significantly reduce dependency on the grid. Using DigSilent PowerFactory software, a quasi-dynamic model has been developed to determine the behavior of the network over a year. In addition, contingency analyses and short-circuit studies were conducted to evaluate the resilience of the network and overall robustness. Results verify the system's capacity to maintain security and stability under fault conditions and unexpected events. This work highlights the critical role of advanced modelling and simulation in designing resilient power systems, especially when integrating intermittent renewable energy sources. It provides valuable insights and a strategic framework for enhancing grid stability and guiding the future development of sustainable, low-carbon energy infrastructures.
