| Abstract | This paper presents a Monte-Carlo based approach for probabilistic estimation of rated demand at bulk supply point at different times during the day. The required data are substation measured RMS real power, reactive power and voltage. Along with component-based load modeling approach, Monte-Carlo simulation is used to generate all possible combinations of percentages of different load categories participating under the total demand and calculate the corresponding per-unit total demand for every possible voltage. After the calculation, a probabilistic density function which shows the probabilistic distribution of the per-unit total demand can be generated. Rated demand is obtained by dividing the actual demand by the corresponding per-unit demand, and its probabilistic distribution can be obtained via either inverse cumulative distribution function (ICDF) regeneration in MATLAB or Gaussian distribution fitting. The result will help developing more accurate load models especially for load modeling with long timeframe or self-disconnections, and it will also enable validation of load disaggregation at given time in real system. |

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.
