Game Iterative Robust Optimization Strategy for AC / DC Distribution Systems Considering Source Load Uncertainty

Abstract

With the wide access of distributed generation and diversified loads in AC / DC distribution system and the uncertainty fluctuation of source load, it will bring great challenges to the planning, control and operation of AC / DC distribution network. Based on this, this paper proposes a game iterative robust optimization strategy for AC / DC distribution system considering the source load uncertainty. The game between power grid dispatcher and nature realizes the robust optimization under the condition of distributed generation random output, minimizes the standard deviation of network loss and the number of possible safety limit excesses of the system, avoids the extreme adverse effects caused by the uncertainty of distributed generation, and ensures the operation safety of the system. It provides a reference for the optimal operation scheduling of AC / DC distribution system.
