Impact of Advanced Load-Frequency Control on Optimal Size of Battery Energy Storage in Islanded Microgrid System

The application of battery energy storage (BES) in microgrid systems has attracted much attention recent years. It is because the BES able to store excess power and discharge its when needed. In islanded systems, starting be considered as a unit that can regulate system frequency. control used display frequency regulation performance called load-frequency (LFC). However, this participation resulted large size high expansion planning cost. paper, an advanced LFC limitation compared traditional proposed. proposed implies droop base limitations. Compared LFC, reduce costs. A simulation was done validate performance. results numerical showed participated reducing operation directly led reduction study selection conducted draw practicality sizing solutions.
