| Abstract | Undervoltage load shedding (UVLS) has been considered by some utilities as a cost-effective corrective tool to overcome voltage instability and abnormal voltage conditions. Load modeling is an important aspect for voltage stability studies and real time system controls pertinent to UVLS. At a given bus, a load would be an aggregate of load elements that would differ in their static and dynamic performance. Also at load centers, aggregate loads would encompass system components of particular characteristics such as load tap changers, SVC's and in-plant generation. Modeling aggregated loads should reflect the nature of load components and fit the applications of the model in studies and real time controls. In a tutorial style, This work discusses the evolution of static and dynamic load models for voltage stability and examines their applicability to UVLS. Load modeling approaches were listed as deterministic, generic and stochastic. Concerns and recommendations were given for adopting one approach or a combination of approaches in aggregate load modeling for UVLS. Load models validation and verification is emphasized especially when using generic or stochastic models. |

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.
