 Electric grid dependence on the configuration of a small-scale wind and solar power hybrid systemM. Mikati, M. Santos and C. Armenta Renewable Energy, 2013, vol. 57, issue C, 587-593 Abstract: Results are presented from the modeling of a small-scale distributed power system containing power demands, photovoltaic arrays, small-scale wind turbines and an electric grid connection. Detailed models of the photovoltaic array and the wind turbine are briefly explained in addition to the solar and wind recourse models. A subunit is defined to consist of a power demand together with power contributors. It is shown how the grid dependency (or renewable energy contribution) is affected by the connection of subunits and according to the relationship between the power demand patterns and renewable resource patterns. The outcome from several case studies is presented using simulated power demands and renewable resources. In a scenario with subunit power demands characteristic for a large household and a small factory, it is shown that the coupling of subunits reduces annual grid power transfers by more than 10% and increases the renewable power contribution to the demand by almost 7%.
