| Abstract | Nowadays, a wind turbine generator (WTG) is required to provide control capabilities regarding an output power. Under this scenario, this paper presents a frequency control method by coordination control of the WTG and a battery using load estimation by a disturbance observer for isolated island. The load variation is reduced by the WTG using pitch angle control in low frequency domain and the battery charge/discharge in high frequency domain. The output command for the battery is determined according to the battery energy storage ratio, the high frequency component of the frequency deviation and the load variation. By using the proposed method, the rated capacity of the battery can be reduced by reducing charge/discharge in long-term. Besides, generalized predictive control (GPC) is applied in the pitch angle control system of the WTG to obtain good response and robustness. Simulation results demonstrate 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.
