Load Management Effect on Optimum Sizing of Stand-alone Hybrid Distributed Generation

This paper presents an optimum sizing assessment for stand-alone hybrid distributed energy system feeding a sub-village sized household community in the rural areas, affected by loading types based on demand side management principle. Simulations are carried out over the combination of hybrid power generation taking into account PV-battery, wind turbine, and diesel generator. Three loading management in which considered in this study are peak clipping, load shifting, and valley filling. Optimum hybrid generation sizing for each loading type is subject to minimum cost of energy. Besides, renewable generation fraction provided system optimum sizing is analyzed accordingly. The simulation result reveals that the least cost of energy is achieved by load shifting scheme with USD 0.39/kWh taking into account the combination of PV-battery, wind turbine, and diesel generator. In addition, the largest renewable energy fraction obtained from load shifting type as well, accounted for 73
