Abstract

This paper proposes a transmissiondistribution interaction multiobjective dynamic random fuzzy optimal power flow method for wind integrated power system. It is a breakthrough of the traditional independent optimal power flow method for transmission and distribution network and that the distribution network is seen as load. Considering bidirectional power interaction between active distribution network (ADN) and transmission system (TS) and the randomfuzzy nature of wind power injection, with multiobjectives of economic lowcarbon and lossreduction, with respect to steadystate security and based on randomfuzzy chance constraint programming, transmissiondistribution interaction multiobjective dynamic randomfuzzy optimal power flow model is established. Randomfuzzy power flow of transmissiondistribution system is calculated through the randomfuzzy simulation, Newton Ralph method and forwardbackward sweep method. Based on this and considering transmissiondistribution interaction power and voltage, Pareto optimal frontier of each time period is obtained through lookahead and NASAII, and the maximizingsatisfaction method is adopted in decisionmaking. An illustration case based on modified IEEE 30 transmission system and IEEE 33 distribution system verifies the feasibility and superiority of the proposed method.
