A Robust Planning Considering Multiple Uncertainties of Distributed Generation

With a large number of uncertain distributed power supply access to the distribution network, increasing multiple uncertainties in distribution networks brings new challenges to its planning. Considering the uncertainty of load and wind speed, this paper proposes a robust planning method considering multiple uncertainties for distribution network. Firstly, based on life cycle cost and robust optimization, a two- layer robust planning model considering multiple uncertainties is constructed. Then the upper planning scheme is verified with the worst scenario. Finally, the IEEE33 node is used for simulation analysis. Simulation results based on standard example verify the rationality and effectiveness of the proposed method.
