- Determination of ESS Capacity for Introducing the Distributed Generation Facilities in Chuja Island
- In this dissertation, the modeling of distributed generation facilities for the power system of Chuja island is performed for the energy independence and carbon-free island. The electric power facilities are modeled with consideration of renewable grid code and power source regulation. Through the modeling result, the most stable configuration of electric power facilities is proposed.
In the simulation, the wind turbine system, photovoltaic system and ESS implement the PQ control, and diesel generator implement the CVCF control.
The microgrid modeling of Chuja island is proceeded with consideration of two points of view for the frequency variation and the depression rate of renewable energy by using the PSCAD/EMTDC simulation program and MATLAB.
1) Analysis of the frequency variation on the capacity of distributed generation.
2) Analysis of the depression rate of renewable energy on the capacity of distributed generation.
The capacity of renewable energy and ESS have been estimated with consideration of the constant power range of disel generator and the stabilization of Chuja power system. By extension of renewable energy, the capacity range of ESS has been proposed.
This research is considered to contribute widely to capacity estimation of electric power facilities for stand-alone microgrid in the future.
