Predictive Control Method for Active Distribution Networks Considering Information Failure

Information system data transmission delays, packet loss, and bit errors will cause the information collected by the distribution network control center to deviate from the true value, and as the information failure problem intensifies, the original optimized control strategy cannot meet actual needs. A predictive control method considering the information failure of the distribution network under the cyber-physical fusion system is proposed. Aiming at the information failure problem in CPS, the information elements, routing model and link model are established. Then, combining with the real-time dispatching process of distribution network, a coordination optimization model of active distribution network considering information failure is proposed to minimize the cost. Predictive control model is used to adjust various distributed energy sources. Finally, through the simulation analysis of the improved IEEE33-node distribution network, the feasibility and effectiveness of the proposed method are verified, and the difference of different information failure cases is analyzed.
