Summary
Over the last years, power systems have changed rapidly with the expanding usage of renewable energy, especially photovoltaic (PV) generation. While this shift helps to meet the long-term target of sustainability, it creates new operational challenges for utilities, specifically in terms of system stability and recovery following major outages. Battery Energy Storage
Read more Read lessSystems (BESS) are, from a utility standpoint, one of the most versatile instruments available to cope with such challenges. At SEC (Saudi Electricity Company), large-scale BESS projects have been developed under hostile environmental conditions such as extremely elevated ambient temperatures. Operational experience has demonstrated that, when appropriately engineered, BESS can reliably support daily grid operation as well as black-start capability.
This is a departure from the traditional dependence on diesel generators and gas turbines for system restoration. In this paper we present such a case study with focused analysis of the possibility of a grid-forming BESS coordinated with PV generation to restore and reconnect a transmission-level substation. Emphasis is placed on real operating performance including transformer energization; frequency response; voltage stability; and synchronization with the main grid. The results validate fast response and stable behaviour with no direct emissions from
BESS, assuming suitable control tuning, and with consideration in the form of thermal design.
