A Comparative Analysis of Electricity Consumption Flexibility in Different Industrial Plant Configurations
The flexibility of industrial power consumption plays a key role in the transition to renewable energy systems, contributing to grid stability, cost reduction and decarbonization efforts. This paper presents a novel methodology to quantify and optimize the flexibility of electricity consumption in manufacturing plants. The proposed model is applied to actual cement and steel plant configurations. Comparative simulations performed with the model reveal significant differences in flexibility and cost-effectiveness, driven by factors such as production capacity, downstream process demand, storage capacity, and operational constraints. A comprehensive sensitivity analysis further clarifies the impact of various parameters on production optimization and flexibility savings. Specifically, as demand approaches production levels, flexibility decreases. Although increasing storage capacity typically reduces production costs, the benefits diminish above a certain threshold. The results provide valuable information for industrial operators wishing to improve operational efficiency, reduce costs and increase the flexibility of their operations.
