Frequency Control in an Isolated Power System By Using Optimizing a BESS Technology

This paper present optimal sizing of the battery energy storing system(BESS) for controlling the frequency fluctuations in a isolated power system, and it also used as revolving reserve in a small isolated power system. The flow chart is used for controlling the state of limits of battery energy. Statistical simulations are performed on LFC of the isolated system. This BESS technology developed in isolated power system for attains maximum expected effectiveness of the device. The BESS can add to considerably the power system stability, the grid security and the planning flexibility for a small isolated power system with low network inertia. In the meantime, it fulfills the frequency control requirements with a high predictable economic effectiveness.
