Optimized Design of a Hybrid Microgrid using Renewable Resources Considering Different Dispatch Strategies

This research work designs and evaluates an optimal hybrid microgrid using various renewable resources considering different dispatch strategies. In this work, the optimal sizing, cost analysis and harmful gas emission calculation of the proposed Yousufpur microgrid is done using HOMER Pro software platform. The feasibility analysis of the proposed microgrid and power system response analysis have been conducted in MATLAB/Simulink platform and according to the performance of various dispatch strategies, best and worst dispatch strategies for the proposed location have been determined. A comparative analysis between the proposed and other hybrid systems is also presented in the last part of the work. The hybrid microgrid consists of solar PV, wind turbine, diesel generator, battery and converter unit. In this work, a load demand of 27.31 kW has been successfully satisfied using five different dispatch strategies: cycle charging, combined dispatch, generator order, load following and homer predictive dispatch strategy. LF dispatch has been found to be the best strategy with minimized cost and best power system responses. The analysis done is also applicable for any location in the world having same load demand and meteorological profile.
