"Pembangkit Listrik Tenaga Bayu (PLTB) skala kecil merupakan pembangkit listrik tenaga angin dengan kapasitas daya dibawah 50 kW.[8] Untuk menghemat biaya pengeluaran untuk sistem mekanik PLTB maka pada tesis ini didesain PLTB dengan jari-jari turbin, rasio gear gearbox dan sudu pitch turbin konstan/tetap. Pada sistem PLTB dengan sudu pitch tetap, jika kecepatan angin lebih besar dari batas kecepatan angin maksimum maka sistem harus dimatikan karena akan melebihi batas torsi dan arus generator sehingga dapat merusak generator. Dengan demikian pada kecepatan angin lebih besar dari kecepatan angin maksimum, field weakening dibutuhkan untuk membuat generator dapat bekerja dengan kecepatan putar rotor lebih besar dari batas kecepatan putar rotornya dengan cara melemahkanan fluks generator sehingga arus dan torsinya mengecil. Daya, torsi dan arus generator dapat dikendalikan sesuai batasannya dengan mengendalikan kecepatan putar rotornya sehingga generator dapat mensuplai daya maksimum. Maka dengan menggunakan field weakening, generator dapat mensuplai daya walaupun kecepatan angin melebihi kecepatan maksimum.

Small wind turbin is wind power plants with a capacity below 50 kW.[8] To reduce cost for the mechanical systems of wind tubin in this thesis was designed wind turbin with turbine radius constant , gear ratio gearbox constant and turbine blade pitch constant / fixed. In the wind turbine system with fixed pitch blades, if wind speed is greater than maximum wind speed limit, the system should be shut down because it would exceed the limits of torque and current generator, which can damage the generator. Thus, if wind speed is greater than the maximum wind speed, field weakening is required to make the generator can work with rotor rotational speed larger than rotor rotational speed limit with flux weakening so that generator current and torque decreases. Power, torque and current generator can be controlled by controlling according rotor rotational speed so generator can supply the maximum power. Then, with field weakening, generator can supply power although wind speed exceeds maximum speed."

"Significant changes over the past decade in computing technology, along with widespread deregulation of electricity industries, have impacted on power plant operations while affording engineers the opportunity to introduce monitoring and plant-wide control schemes which were previously unfeasible. Contributors of world-class excellence are brought together in Thermal Power Plant Simulation and Control to illustrate how current areas of research can be applied to power plant operation, leading to enhanced unit performance, asset management and plant competitiveness through intelligent monitoring and control strategies."

"Dengan diterapkannya jaringan listrik konvensional pada sistem kelistrikan Indonesia, pemenuhan kebutuhan listrik yang meningkat pada waktu beban puncak menyebabkan tingginya biaya operasional penyediaan listrik pada saat itu. Hal ini dapat diantisipasi dengan melibatkan konsumen untuk ikut berperan aktif menghasilkan energi listrik bersama dengan Perusahaan Listrik Negara (PT. PLN). Virtual Power Plant dapat menjadi pilihan dalam mengendalikan berbagai jenis pembangkit dan terintegrasi untuk memenuhi kebutuhan listrik, termasuk mengendalikan energi listrik yang berasal dari rumah pelanggan. Oleh karena itu, diperlukan perancangan dua model diantranya Master Controller Unit dan Slave Controller Unit dalam sistem Centralized Virtual Power Plant yang dapat mengintegrasikan beberapa pembangkit, dan mendukung PLN dalam menghadapi kebutuhan energi listrik pada waktu beban puncak. Virtual Power Plant memudahkan pengguna untuk melakukan monitoring sistem pembangkit listrik dan melakukan transaksi energi listrik dengan PLN.

By implementing conventional power grids in Indonesian electrical system, fulfilling the increase of power demand during peak causes a high operational cost for electrical supply at that time. It can be anticipated by involving the consumers to actively contribute producing energy with State Electricity Company (PLN). Virtual Power Plants would be an option in controlling various types of power plants and be integrated in order to suffice the electricity demand, including controlling electrical energy originating from customers' houses. Therefore, it is need to design two architectural models as a Master Controller Unit and a Slave Controller Unit in a Centralized Virtual Power Plant System that can integrate several power plants, and support PLN when facing the electrical energy demand at peak load times. The Virtual Power Plant makes it easy for users to monitor power generation systems and conduct electrical energy transactions with PLN."

"This book describes an original improvement in power quality of photovoltaic generation systems obtained by the use of a multilevel inverter implemented with level doubling network (LDN). Modulation principles and harmonic analysis of output voltages are proposed and introduced in detail for both single and three-phase LDN configurations. The analysis is then extended to dc-link current and voltage, with emphasis to low-frequency harmonics and switching frequency ripple. This work represents the first comprehensive implementation of maximum power point tracking (MPPT) schemes using the ripple correlation control (RCC) algorithm in the presence of multiple ripple harmonics, such as in the case of multi­level inverters. Numerical simulations and experimental tests are carefully reported here, together with practical insights into the design of dc-link capacitors."

"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."
