Abstract | With the development of plug-in hybrid electric vehicles (PHEVs), it is a necessary trend for residential intelligent evolution that PHEVs are widely accepted by family and can be charged at home. According to the power usage characters of home electric appliances, we divide residential appliances into PHEVs, scheduled loads (soft loads) and unscheduled loads (hard loads). PHEVs can be used as storage device when they are idle. Assuming that the price of electricity is time-varying, we propose a method to optimally charge PHEV with predicted price and schedule PHEV charge and discharge to minimize household electricity cost by supplying its electricity to soft loads. We apply a simple and efficient weighted average price prediction filter to the actual hourly-based price values with an hourly pricing program from Ameren Illinois on January, 2012, and compare the three charge patterns' cost to choose the optimum charging mode. Two consecutive days are considered to be a model unit, and there are three kinds of situation in accordance with the state of PHEV. Simulation results show that in these three states with electricity price forecasting and residential load schedule control tactic, the electricity cost is significantly decreased by using the battery as a storage device. Meanwhile, our method can also alleviate the phenomenon of overload and secondary peak time in the smart grid. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
