Optimization of load dispatch strategies for an islanded microgrid connected with renewable energy sources

This paper evaluates the design and optimization of an islanded hybrid microgrid for various load dispatch strategies by assessing the optimal sizing of each component, the power system responses and different cost analysis of the microgrid. Four divisions of the northern side of Bangladesh namely, Mymensingh, Rangpur, Rajshahi and Sylhet hybrid microgrids incorporating solar PV, wind turbine, battery storage, diesel generator and a load of 27.31 kW have been optimized for five different dispatch strategies: (i) Load Following, (ii) Cycle Charging, (iii) Generator Order, (iv) Combined Dispatch and (v) HOMER predictive dispatch strategy. The proposed microgrids have been optimized to reduce the Net Present Cost, CO2 emission and Levelized Cost of Energy. All the five dispatch strategies for the four…
