The intermittent character of wind power results in volatile power production. Therefore, wind farm owners experience difficulties in robust production planning. This research investigates the effects of grid-scale battery storage integrated with wind energy on system resilience, in the context of technical performance and economic viability. A microgrid model is developed in Modelon Impact to simulate and optimize the technical performance. The model consists of a wind turbine, battery storage, electricity grid, and load demand. To assess technical performance, a planned production profile is constructed based on the average wind speed over 12-hour intervals over a week. The study examines how accurately the actual wind farm production and the planned production profile align. It is found that integrating battery storage reduces electricity required for grid balance by 8%, 11%, and 18% for battery capacities of 1 MW, 2 MW, and 5 MW, respectively. Furthermore, a techno-economic analysis is conducted to evaluate the Net Present Value of the system. Results indicate a negative result for both the wind turbine and battery components, mainly due to low revenue generation from the wind turbine and high investment costs associated with battery deployment. Optimization of the system is achieved through the interior point method, focusing on minimizing battery controls and operational costs. This made the battery operation more smoothly, however at the cost of more electricity being required for grid balance. Integrating wind power with grid-scale batteries strengthens energy systems and ensures resilience for the future. Keyphrases: Battery storage, Resilience, production planning, windpower
