| Abstract | The research on wind generation and hydro generation is deeply and widely at home and abroad. Hydro generation has become the best technological way to eliminate the impact of fluctuations of wind generation. With the development of wind generation in our country, there are many researching on the hydro-wind generation coordinated operations. But researching on the influence of forecasting precision to the hydro-wind generation coordinated operation is not reported in our country. This paper makes research and discussion in this field. Firstly, the three different wind prediction models will be studied in this paper, which are persistence forecasting model, ARIMA forecasting model and improved BP neural network forecasting model. According to the specific example, improved BP network forecasting model is better than ARIMA forecasting model and ARIMA forecasting model is better than persistence forecasting model in the same situation. Secondly, building different models of the hydro-wind generation coordinated operation is based on the above three different wind forecasting models. In the model, daily load is supplied by both wind generation and hydro generation, but wind generation must be used up and then the other is supplied by hydro generation. Because wind generation cannot be stored, the target function can only choose the variables related the hydro generation when the model of the hydro-wind generation coordinated operation is established. The present study shows that the more accurate the Wind generation prediction is, the less its influences over the water assumption in hydro generation stations are. |

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.
