摘要：

Delay, packet loss and error codes of data transmission in information systems will cause the information collected by the distribution network control center to deviate from the true value. Therefore, a multi-scenario two-stage stochastic control method is proposed, which considers the information failure of the distribution network in the cyber-physical system. Firstly, the data and predicted values of each sampling point in the trend optimization cycle are discretized into different scenario sets based on the information failure conditions that may occur. With the goal of minimizing the total cost, the stochastic model predictive control is used to perform real-time rolling optimization of each scenario in the cycle and coordinate the output of various distributed energy sources. Secondly, in a shorter real-time correction cycle, according to the fine coordination of dispatchable abilities, the impact of information failure on the distribution network can be further reduced. Finally, in the modified IEEE 33-node distribution network, it is verified that the proposed method can effectively improve the safety and economy of the coordination and optimization of the distribution network when information failure is considered, and the difference and sensitivity of different information failure situations are also analyzed. © 2021 Automation of Electric Power Systems Press.
