Resumo

The fluctuating demand on a power grid can alter its profile voltage and reach the current grid’s limits. Moreover, adding distributed generators, such as photovoltaic (PV) microgeneration, can speed up this process due to the resistive-inductive properties of grid cables and the change in the current flow, sometimes consumed, sometimes injected. As a result, it becomes challenging to online predict the maximum allowable power generation for each PV system on the grid without exceeding voltage and current limits.
