Adaptive control for biomass-based diesel-wind system

Control of autonomous diesel-wind systems is difficult because of time-varying dynamical properties, most of them as a result of plant nonstationary, nonlinearity and random disturbances. In this paper, the system is composed of a pitch controlled wind turbine with an induction generator connected to an AC busbar in parallel with a diesel generator set having a synchronous generator. A power plant can generate electric power using biomass from olive trees in Spain. The recursive least squares method and minimum-variance control algorithm are implemented to design the controller. This paper considers the application of an adaptive control methodology that allows the controller to automatically adjust to changing process variables and thereby provide uniform response over a wide range of operating conditions.
