ABSTRACT
DEVELOPMENT OF A REAL-TIME SCHEDULER SYSTEM WITH API FOR LINUX BASED SMART GRID SYSTEM
By Ivan Surya
Prof. Dr.-Ing. Egon Ortjohann, Advisor Dr. Rusman Rusyadi, B.Sc, M.Sc, Co-Advisor
SWISS GERMAN UNIVERISTY
Presently, smart grid concept has been promoted worldwide. The main targets of the concept are to increase the efficiency of power system operation and facilitate the grid integration of renewable energy sources. In this thesis scheduler software functions have to be developed on Linux operating system platform. The functions are expected to enable smart power system operation on distribution management system (DMS). In combination with communication technologies, the functions can interact with distributed intelligent power components. More specifically, the tasks in this thesis include enabling multi-controller capability for the real-time scheduler system, using web service description language to controller the scheduler functions, executing binary files stored in the database to operate the management system, implementing a professional logging system, and developing an API for the real-time scheduler system.
Keywords: Smart Grid, Controller, Scheduler, Task, RabbitMQ, MySQL, JSON, C Programming, Notepad++, Rapid Prototyping, Renewable Energy, Mantis BugTracker, SmartSVN.

DEDICATION
I dedicate this work to my family, my advisor and co-advisor, all of my lecturers, my supervisor and my closest friends.
ACKNOWLEDGEMENTS
First of all I wish to express my gratitude to Prof. Dr.-Ing. Egon Ortjohann and the people that works at Power Systems and Power Economics Laboratory in South Westphalia University of Applied Science for their support and patience.
I would also like to especially thank Mr. Andreas Schmelter and Mr. Sasiphong Leksawat who both have greatly helped me for completing this thesis work and taught me how to write a good and professional looking documentation.
I thank my family, especially my father and mother who are always there when I am at my worst and to always have a confidence in my abilities to not only complete a degree, but to complete it with excellence.
To all lecturers of Mechatronics Engineering for knowledges and insights that they have shared to me during my study at Swiss German University.
To my friend, Janice Yip who indirectly and constantly motivates me to finish my work.
To my colleague, Kelvin Susanto for his help in my thesis work notably in WSDL.
And last but not least, to my Mechatronics Engineering 2012 classmates, especially my group of close friends; Charles Logis, Dennis Adrian Tjahjadi, William Irawan, Nicolas Aditya Siswanto, Johan Soegiharto, Samuel Loanka, Kevin Tirtaatmadja, and Kevin Susanto for the last 4 years and for their support and assistance during my thesis work.
