Penetration of renewable energy sources introduces variability in the electric power generation. It causes grid voltage fluctuations that adversely affect operation of critical loads. Mitigation of these fluctuations is traditionally achieved by compensating for the reactive power absorbed at the point of common coupling.

Abstract
Penetration of renewable energy sources introduces variability in the electric power generation. It causes grid voltage fluctuations that adversely affect operation of critical loads. Mitigation of these fluctuations is traditionally achieved by compensating for the reactive power absorbed at the point of common coupling. In the paper, the Smart Transformer (ST) load control is applied to adjust the active power absorbed by the noncritical loads. In the paper, this application of ST load control is explicated showing its enforceability in the presence of distribution lines with resistive parameters of the same order as the reactive ones. Results obtained for a study case are also given that support the theoretical findings.Pubblicazioni consigliate
