| Abstract | The policy of transaction mode of direct electricity purchase by large consumers will further reduce the power system scheduling space. When large-scale non-controllable wind turbines and photovoltaic power stations are connected to the system, the optimal scheduling of the system will face even more severe challenges. In order to analyse the impact of the direct purchase of large consumers on the system capacity of renewable energy, this paper proposes a scheduling model of power system with renewable energy and transaction mode of direct electricity purchase by large consumers considering network security constraints. By taking into account the network security constraints, this model can compute large power system and analyse the impact of the direct electricity purchase unit access node on renewable consumption capacity of the system. To illustrate the effectiveness of the proposed model, a real power system in a northern province of China is used in the case study. The consumed renewable energy is calculated and the reason for the wind and solar power curtailment is analysed. The influence of real-time price, contract size, and the unit access node of the direct electricity purchase on renewable energy consumption capacity of the system is analysed. |

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.
