Operation and impact of energy storage system in an industrial microgrid

This paper analyzes the performance of a stone crushing facility powered by an islanded microgrid comprising two natural gas engine driven generator sets (also known as gensets). The goal is to achieve the microgrid performance in accordance with the ISO 8528-5 Standard. For improving the system frequency response, different approaches are evaluated including applying underfrequency load shedding and increasing generator inertia. However, it is shown that integration of energy storage system with fast frequency controls offers the best solution for satisfying the ISO 8528-5 Standard. Results from modeling and simulation using MATLAB/Simulink are presented to show the impact on microgrid performance.
