“Proper strategy to support the renewable energy sources in power market considering the improvement of voltage quality”

In this paper, the effect of fuel cell (FC) unit as distributed generation, on network bus voltages has been studied. Under different loading conditions, considering the voltage limit which is determined by the standard, the minimum and maximum power that FC unit can inject to the network has been calculated. Nowadays, participate in competitive market for the renewable energy sources are not possible. So in this paper, two supportive strategies have been supposed. These strategies, applied to a 77 buses real life distribution network and the results have been compared.
