| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 100 === Along with the environmental concern and the advance of technology of renewable energy generation, the proportion of renewable energy in energy power systems is increasing. The most commonly seen renewable energy resources are photovoltaic(PV) and wind turbines.Microgrid studies have attracted much attention in recent yeays. Microgirds consist of several renewable sources (or distributed generations) and local loads, which provide the solution to provide premium quality of power to remote or specified area.
It is necessary to perform computer simulation for power system planning and study. Establishing the electrical power systems takes long time and costly money. Therefore, before the actual system is built, all possible responses of the system should be known and then the design can be modified to avoid negative impact of the system. As a result, computer simulation is important for the development and study of the micogrid, such as modeling and verification of renewable energy resources, testing under possible scenario, or testing the real hardware.
The main purposes of the thesis are that building models of renewable energy sources, optimal operation strategy and energy management system. Moreover, in order to overcome limitations of off-line simulations (such as: time-consuming jobs, numerical oscillation, and lack the capability of interfacing with real devices), real-time simulation techniques are needed. Then, compartions between the computed-time and accuracy of off-line simulations with these of real-time simulations are performed.
