"This Green Book offers the outstanding expertise of CIGRE professionals about Flexible AC Transmission Systems (FACTS) in one concise handbook. FACTS are used to enhance AC power networks, by providing fast control of power flows and AC voltage and AC phase angles. They can be used to defer the need for additional power lines, by controlling the power flow on lines to achieve maximum utilisation of the existing lines, and/or by improving the power quality, e.g. when large disturbing loads are connected to the network.
This Green Book on FACTS provides comprehensive information about the use of Power Electronics for AC system control and for Power Quality Improvement in its over 1000 pages. This book has been written by experts in the field, who come from Transmission System Operators, Network owners, manufacturers, and consultants in this field.
This Green Book on FACTS covers a large range of topics in its 6 sections, as follows:
1. AC Systems Characteristics, AC network control using conventional means and AC network control using FACTS Controllers
2. Technical Descriptions of all current FACTS controllers, power electronic Topologies for FACTS, SVCs, STATCOM, TCSC and the UPFC and its variations
3. Application Examples of all FACTS controllers, which include a description of controllers using saturation of iron as well as examples of all current FACTS controllers
4. Planning and Procurement, including economic appraisals and cost benefit analysis, planning studies, environmental considerations, functional specifications
5. Implementation of FACTS controllers, including integration and design studies, equipment design and testing and commissioning
6. FACTS operation and lifetime management."

"The book covers comprehensively a range of power-system control problems: from steady-state voltage and power flow control, to voltage and reactive power control, to voltage stability control, to small signal stability control using FACTS controllers.
In the six years since the first edition of the book has been published research on the FACTS has continued to flourish while renewable energy has developed into a mature and booming global green business. The second edition reflects the new developments in converter configuration, smart grid technologies, super power grid developments worldwide, new approaches for FACTS control design, new controllers for distribution system control, and power electronic controllers in wind generation operation and control. The latest trends of VSC-HVDC with multilevel architecture have been included and four completely new chapters have been added devoted to Multi-Agent Systems for Coordinated Control of FACTS-devices, Power System Stability Control using FACTS with Multiple Operating Points, Control of a Looping Device in a Distribution System, and Power Electronic Control for Wind Generation."

"Seiring dengan perkembangan jaman, kebutuhan manusia semakin meningkat dan teknologi semakin berkembang, hal ini juga akan mempengaruhi tingkat permintaan akan tenaga listrik. Kebutuhan listrik masyarakat Indonesia semakin meningkat setiap tahunnya, menurut RUPTL (Rencana Usaha Penyediaan Tenaga Listrik) PT. PLN 2013-2022, konsumsi listrik Indonesia diperkirakan akan meningkat dari 189 TWh pada tahun 2013 menjadi 386 TWh pada tahun 2022. Untuk itu, dimungkinkan memberikan kesempatan pada pihak ketiga non-IPP untuk membangun dan menyediakan listrik dengan melalui skema power wheeling. Power wheeling merupakan pemanfaatan suatu jaringan tenaga listrik oleh penyedia listrik lain sebagai suatu alternatif permasalahan penyediaan pasokan serta keandalan sistem tenaga listrik. Terdapat beberapa metode yang dapat diterapkan pada pemanfaatan bersama jaringan transmisi (PBJT), namun dalam hal ini penulis menggunakan metode MVA-Mile dan Postage Stamp untuk diterapkan pada jalur transmisi 150 kV dan 500 kV pada area Jakarta-Banten dengan menganalisis beberapa permasalahan yang ada pada sistem jaringan transmisi tersebut. Dengan jarak penghantar daya yang sama, penggunaan jalur transmisi 500 kV dan 150 kV dalam penyaluran daya memiliki tingkat efisiensi yang lebih tinggi dibandingkan dengan hanya menggunakan jalur transmisi 150 kV, namun pada sistem yang hanya menggunakan jalur 150 kV lebih mudah dalam perhitungan biaya transmisi.

Along with the development, human needs are increasing and technology is growing, it will also affect the level of demand for electric power. The electricity needs of the people of Indonesia is increasing every year, according to RUPTL (Electrical Power Supply Business Plan) PT. PLN 2013-2022, Indonesia's electricity consumption is expected to increase from 189 TWh in 2013 to 386 TWh in 2022. To that end, it is possible provide opportunities for third-party non-IPP to build and provides electricity to power wheeling through the scheme. Power wheeling is the use of an electric power network by another electricity provider as an alternative to the provision of supply problems and power system reliability. There are several methods that can be applied to the joint utilization of the transmission network (PBJT), but in this case the authors use the method of MVA-Mile and the Postage Stamp to be applied to the transmission lines of 150 kV and 500 kV in the area of Jakarta, Banten by analyzing some of the problems that exist in The transmission network system. With the same power conductor spacing, use of transmission lines of 500 kV and 150 kV in the transmission of power has a higher degree of efficiency compared to only use 150 kV transmission lines, but in a system that only uses 150 kV lines easier in the calculation of transmission cost.

"Penggunaan dispatching rule dalam menentukan urutan pengerjaan produk dalam flexible manufacturing system dapat memberikan solusi yang kurang baik apabila dispatching rule yang digunakan tidak sesuai. Pada tesis ini akan diperlihatkan perbandingan penggunaan beberapa dispatching rule baku dalam menentukan jadwal produksi, seperti First Come First Served (FCFS), Shortest Processing Time (SPT), Longest Processing Time (LPT), dan Earliest Due Date (EDD) serta sebuah usulan yang mempertimbangkan waktu terbuang untuk menunggu urutan pengerjaan produk pada mesin yang sama dalam waktu yang bersamaan dengan menggunakan alat bantu simulasi model.
Pada tesis ini juga akan diciptakan model FMS dalam perangkat lunak, untuk kemudian disimulasikan menurut dispatching rules masing-masing, sehingga waktu penyelesaian masing-masing produk dan tardiness yang tercatat dalam hasil simulasi dapat dianalisa dan kemudian dibandingkan agar dapat dipilih untuk mendapatkan dispatching rules yang sesuai dan dapat memberikan kinerja yang paling baik. Perencanaan dispatching rule yang sesuai diharapkan dapat mempersingkat waktu penyelesaian tanpa melanggar tenggat waktu.
Hasil yang didapatkan dalam penelitian ini menunjukkan bahwa dispatching rules yang sesuai merupakan kombinasi dispatching rule EDD dengan tetap mempertimbangkan waktu waktu terbuang untuk menunggu urutan pengerjaan produk pada mesin yang sama dalam waktu yang bersamaan melalui tenggat waktu minimum yang dimiliki masing-masing kombinasi urutan pengerjaan produk.

Dispatching rules, which commonly used in determining job execution sequences, should be well planned in order to avoid bad solution caused by the usage of improper dispatching rules. In this thesis, the comparison of several dispatching rules is made to establish a compact production schedule on an FMS using a model simulation, such as First Come First Served (FCFS), Shortest Processing Time (SPT), Longest Processing Time (LPT), Earliest Due Date (EDD) and a proposal to consider the wasted time caused in waiting execution on a same machine at a same time.
In this thesis, a model of FMS environment will be built on a software, and sequences which were produced on each dispatching rules, will be simulated based on the model created, for later the recorded value of completion time and tardiness of each product could be analyzed and compared further to gain a proper dispatching rule in giving the best performance. The proper dispatching rules planning will improve the completion time performance without violating the due dates.
The result from the case on this thesis will show that the proper dispatching rule is a combination between EDD and the proposal of considering the wasted waiting time with the concern of minimum due dates attribute owned by each product execution.
