Abstract | In this paper, a reinforcement learning based adaptive critic controller is proposed for the power capture control of variable-speed wind energy conversion systems (WECSs). The control objective is to optimize the power capture from wind by tracking the maximum power curve and minimize a predefined long-term cost function in the mean time. By minimizing the long-term cost function, both the power capture and the life time of mechanical part of a wind turbine are considered as opposed to most of existing literatures. The developed controller consists of an action network and a critic network. The critic network is introduced to evaluate the performance of the action network, and learn the cost-to-go function in an online manner. The estimate of cost-to-go function is then transmitted to the action network. The action network is utilized to provide the optimal generator torque rate with the help of the estimate of cost-to-go function. Here, a two-layer neural network structure is employed for both the action and critic network. Finally, the performance of the proposed controller is evaluated on a 1.5MW three-blade wind turbine in simulating environment. |

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.
