Employing Battery Storage Systems to Improve Power System Survivability

This paper presents the employment of battery storage systems (BSSs) to improve power system survivability. This application of BSSs is based on setting BSS charging/discharging as responses to integrating distributed generation units and/or adjusting load demands (load-side activities). The improvement of power system survivability is quantified by the survivability index Γ, which can exceed its boundary values due to load-side activities. The improvement of power system survivability is achieved by maintaining Γ within its boundary values post a load-side activity. The proposed approach to improve power system survivability is implemented and tested for the Barbados power system. Tests are conducted for integrating solar power generation units, and implementing demand response. Test results show that accurate BSS charging/discharging can maintain the index Γ within its boundary values post load-side activities.
