| Abstract | Among the main electric components in power systems, load models have great effect on power system time- domain dynamic simulations. However, owing to the characteristics such as time-variation, randomness and so on, it is difficult to construct load model. In addition, in order to analyze the uncertainties, Monte-Carlo method is often used to estimate the probability density function of the desired output, which requires many sample data obtained from repeated simulations, therefore the uncertainty studies on power system stability are few. This paper studies the effect of the uncertainties of dynamic load proportion on power system dynamic stability based on Probabilistic Collocation Method (PCM). It could be concluded that using the proposed method the desired output is directly described as a polynomial in the uncertain parameter of the system. Consequently, high calculation accuracy could be reached by low-dimensionality polynomial functions and fewer time-domain simulations. Cases study verifies the validity of the proposed method. |

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.
