Load frequency control, battery energy storage system, power generation control
This article deals with load frequency control of an interconnected hydrothermal power system considering battery energy storage (BES) system. Area control error (ACE) is used for the control of BES system. Time domain simulations are used to study the performance of the power system and BES system. Results reveal that BES meets sudden requirements of real power load and is very effective in reducing the peak deviations of frequency and tie-power, and also reduces the steady-state values of time error and inadvertent interchange accumulations; as well, settling time is much less.
