"Photovoltaic generation is one of the cleanest forms of energy conversion available. One of the advantages offered by solar energy is its potential to provide sustainable electricity in areas not served by the conventional power grid. Optimisation of photovoltaic power systems details explicit modelling, control and optimisation of the most popular stand-alone applications such as pumping, power supply, and desalination. Each section is concluded by an example using the MATLAB® and Simulink® packages to help the reader understand and evaluate the performance of different photovoltaic systems."

"Penggunaan Pembangkit Listrik Tenaga Bayu makin meningkat sebagai sumber energi listrik terbarukan. Salah satu permasalahan dalam pemanfaatan PLTB adalah pengendalian generator induksi. Pada penelitian ini telah dirancang pengendali RFOC, Full Observer dan pengendali daya sebagai satu kesatuan kendali generator induksi. Tipe generator induksi yang dipakai adalah SCIG. Pengendali Rotor Flux Oriented Control (RFOC) adalah pengendali vektor yang mengatur arus stator. RFOC terdiri dari dua bagian yaitu decoupler dan pengendali PI untuk mengendalikan arus. Pengendali RFOC adalah pengendali yang memerlukan masukan arus stator referensi, arus stator generator dan kecepatan putar rotor generator. Untuk mendapatkan kecepatan putar rotor generator, dalam penelitian ini didesain full order observer sebagai masukan pengendali RFOC sehingga tidak menggunakan sensor kecepatan. Sedangkan pengendali daya didesaian agar daya keluaran generator sesuai dengan daya referensi yang diberikan. Analisa dilakukan berdasarkan hasil simulasi pada MATLAB/Simulink dan C-Mex S-Function. Berdasarkan hasil simulasi, RFOC yang dirancang telah berhasil mengendalikan generator dengan perubahaann arus stator sumbu q, full observer dapat mengestimasi state dengan error 5% pada model dan kecepatan putar dengan error 0.43% dan waktu stabil 1.4s dan pengendali daya bekerja dengan baik.

The use of wind power plants as a source of renewable electric energy is increasing. One of the problems in the utilization wind turbin is the control of an induction generator. In this study, RFOC, Full Observer and Power Controller have been designed as control of induction generator. Induction generator type used is SCIG. Controlling Rotor Flux Oriented Control (RFOC) is a vector controller that regulates the stator currents. RFOC consists of two parts, decoupler and current PI controller. RFOC controller requires input reference stator current, stator current generator and the generator rotor rotational speed.

In this study, instead of speed sensor, full order observer has been used to estimate generator rotor speed. Power controller is used to regulate the generator output power in accordance with the references given. In this study, verification of controller performance has been done by using simulation MATLAB/Simulink. Simulation results show that RFOC, full observer and power controller have achieved its performance. RFOC has control the generator with change of q-axis stator current. Full observer has estimate with 5% error, and rotational speed with 0.43% with 1.4s. Power control have also worked well."

"This book reports on a comprehensive study addressing the dynamic responses of hydropower plants under diverse conditions and disturbances, and analyzes their stability and oscillations. Multiple models based on eight existing hydropower plants in Sweden and China were developed and used for simulations and theoretical analysis with various degrees of complexity and for different purposes, and compared with on-site measurements for validations. The book offers important insights into the understanding of the hydraulic, mechanical and electrical coupling mechanisms, up to market conditions and incentives. It recommends control strategies for a more stable and efficient operation of hydropower plants."
