Abstract | Summary form only given. One of the key issues in wind energy is the control design of the wind energy conversion system (WECS) to achieve an expected performance under both power system and mechanical constraints which are subject to stochastic wind speeds. Quadratic control methods are widely used in the literature for such purposes, e.g., Linear Quadratic Gaussian (LQG) and Model Predictive Control (MPC). In this paper, chance constraints are considered to address the stochastic behavior of the wind speed fluctuation on control inputs and system outputs instead of deterministic constraints in the literature. Also considered are two different models: the first one assumes the wind speed measurement error is Gaussian, where chance constraints can be reduced to deterministic constraints with Gaussian statistics; while the second one assumes the error is norm bounded, which is likely more realistic to practicing engineers, and the problem is formulated as a min-max optimization problem which has not been considered in the literature. Then, both models are formulated as semi-definite programming (SDP) optimization problems that can be solved efficiently with existing software tools. Finally, simulation results are provided to 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.
