Problems solved by technology

Based on this guideline, when a serious information system failure occurs, the load will lose the power support of the DG, causing problems such as overload and low voltage, and deteriorating the system status
If such incidents are prevented by increasing the redundancy of the one-time system, it will undoubtedly reduce the economics of the system

Abstract

The invention discloses a method and system for optimizing the upper limit of injection when a distributed power supply fails in communication. The method for optimizing the upper limit of injection includes: Step S1: according to the failure mode consequence analysis method, establish a correspondence model between communication failure scenarios and link validity states , to obtain the communication failure scenario and the link availability status table; Step S2: Based on the communication failure scenario and the link availability status table, establish a two-layer multi-objective optimization model of the upper limit of the distributed power differential injection; Step S3: Use the interval power flow And the particle swarm intelligent optimization algorithm performs loop iteration on the double-layer multi-objective optimization model to realize the optimization of the upper limit of the differential injection of the disconnected DG.

Description

technical field [0001] The invention belongs to the field of distributed power sources, and in particular relates to a method and a system for optimizing an injection upper limit when a distributed power source has a communication failure. Background technique [0002] A large number of distributed power sources (DG) are connected to the distribution network, and the random fluctuation of the output forces the distribution network to carry out active operation management, resulting in the dependence of the power grid operation status on communication and control. With the increase of DG penetration rate, the dependence of load on DG and the dependence of grid operation status on control are increasing. At this time, if a communication failure occurs, it will inevitably lead to one or more DGs losing considerable controllability, causing the system control performance to decline, resulting in voltage over-limits and power flow overload, resulting in a significant increase in ...
