| Abstract | During power system restoration, it is critical to maintain system frequency stable to avoid any further outage or cascading events. Load pickup is one of the most important tasks to keep generation-load balance for a stable system frequency. In current industry practice, small loads are suggested to be picked up incrementally to avoid any instable frequency dip. However, slow load pickup may prolong the system restoration process. As the fast response energy resources, battery storage system (BSS) can expedite the load pickup by compensating the imbalance between generation and load. In this paper, a battery dispatching strategy is developed for faster and more reliable load pickup in system restoration. The frequency response rates (FRRs) of generators are utilized to pick up loads in each step while maintaining frequency stability. Batteries are used to maximize the load pickup. The State of Charge (SOC) of batteries is monitored and kept within specified limits. Simulation results demonstrate that batteries can support to increase total served energy and reduce system restoration time. The battery charging/discharging time and sequence depends on the generation and load profile, and the size of BSS. This paper further discusses the impact of FRR of BSS on frequency dynamics in load pickup. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
