Power Quality Mitigation in a Distribution Network Using a Battery Energy Storage System

Battery energy storage systems (BESSs) have been proved to be an efficient emerging technology for short-term power storage for power utilization for mitigation of various power quality (PQ) disturbances, stability, reliability, and protection. Apart from all the control algorithms, indirect current control theory (ICCT) has the additional ability for fast regulation of the battery charging level and distributed system stability for transient conditions. This chapter aims to design an ICCT controlled DSTATCOM-BESS configuration for power conditioning in a distribution system with a balanced and unbalanced linear, nonlinear, and induction motor load. This detailed analysis helps beginners in selecting the type of load for the specific BESS-based configuration. The system is analyzed for source voltage, terminal voltage, source current, compensating current, load currents, battery voltage, and battery current based signals.
