WebMar 7, 2016 · This paper presents a systematic switching control method for a variable-speed variable-pitch wind turbine over a wide wind speed region. The whole framework is based on the linear parameter-varying (LPV) control theory, which is an extension of robust control for linear systems to nonlinear ones. WebThere may be considered to be six main sources of energy loss for wind farms; wake effect, availability, electrical efficiency, turbine performance, environmental losses and curtailments, each of which may be subdivided into more detailed loss factors. A rather comprehensive list of potential losses is presented in Table 2.5 below.
