This book helps the researchers and industrialist working on renewable source integration. In this book, an observer based adaptive speed control (OASC) and a multistage adaptive filter (MAF) based control structure, are proposed for on-grid hybrid wind and photovoltaic (PV) system to deal with the two major issues such as peak wind power extraction and mitigation of power quality problems, respectively. The OASC is an adaptive control alongside exhibiting robustness against uncertainties (structured and unstructured). The objective of peak wind power extraction is met through cascaded control, which includes an inner hysteresis current control and an outer speed control based on OASC. The proposed OASC includes a disturbance observer loop with back stepping control. For enhancement of system reliability, another renewable source solar PV array) is integrated at the DC link. Additionally, the performance of the system is tested with various controllers like PI, Fuzzy and Adaptive Neuro Fuzzy Inference System (ANFIS) controllers to get the better response. By going through this book one can easily understand the hybrid renewable energy system and role of controllers in RES.
