Fault Reconfiguration Strategies of Active Distribution Network With Uncertain Factors for Maximum Supply Capacity Enhancement

With a large number of distributed generation connected to the distribution network, total supply capacity network has been improved certain extent. However, due randomness its output, it also brings some challenges reliable operation and restoration power after failure. Based on this, this paper proposes an active reconfiguration strategy with uncertain factors for maximum improvement. Firstly, evaluation index is constructed, under current mode evaluated online through calculation model based N-1 security criterion. Then, uncertainty wind power, photovoltaic electric vehicle DG stochastic prosumer load are considered, random variables generated by Latin hypercube sampling (LHS) their correlation considered. introduces that position sectionalizing switch tie can be adjusted according dispatching demand. output factors, fault proposed. Finally, example illustrates effectiveness correctness in paper. It demonstrated optimize selection Section improve utilization rate energy, give full play recovery potential reduce outage time groups.
