Reactive Power Control of Grid Interactive Battery Energy Storage System for WADC.

The integration of Grid Interactive Battery Energy Storage Systems (GI-BESSs) in energy services, such as peak shaving and load balancing, is a common practice in the modern-day electric power system. However, it is essential to ensure their economic feasibility, such as through their incorporation in Power Oscillation Damping (POD). This paper proposes an optimized control algorithm for a GI-BESS to mitigate low-frequency oscillations by utilizing synchrophasor measurements gathered by the Wide Area Measurement System (WAMS). The proposed algorithm enables the GI-BESS to mitigate inter-area active power oscillation by altering the exchange of reactive power between the grid and the GI-BESS. Thus, by using the proposed algorithm, the GI-BESS can provide power and energy services, simultaneously. Moreover, the effects of this controller on State of Charge (SoC) and dispatched power are assessed. The algorithm is tested on an IEEE 39-bus system and demonstrates that the proposed algorithm improves the damping of inter-area oscillations.
