Modeling and comparative analysis of cost effective hybrid AC/DC micro-grid in coastal area of Bangladesh using AVR and LFC system
This paper highlights about the cost effective optimal modeling of hybrid AC/DC micro-grid for the coastal area of Bangladesh, where distributed energy sources like solar PV, wind energy as well as bio-mas energy are available. For the purpose of research Kuakata is chosen, which is one of the attractive tourist spot of Bangladesh. However, despite being a tourist spot, the electricity generation of this place has not yet been any self-reliance. The discussion of this paper not only circumscribed by the modeling of micro-grid, but also shows the detail of optimizing result with sensitivity analysis. This modeling with its optimal analysis is simulated via HOMER software. The micro-grid can operate on both grid connected mode and islanded mode. This paper proposes an off-grid or standalone micro-grid. In off-grid mode, the voltage and frequency does not remain balanced like grid connected mode. Hence, a new seamless control strategy for islanded mode voltage and frequency control is being proposed in this paper. Automatic voltage regulator (AVR) can be treated as a good solution for voltage control and load frequency control (LFC) technique can be used for frequency tuning. The control strategies applied in this research are simulated via MATLAB Simulink software.
