Distributed Security Dispatch Of Power Systems Based On Controller Information Protection

The distributed economic dispatch method based on consensus algorithms is widely regarded as an important approach for achieving power scheduling.By ensuring consistent information exchange between scheduling units and adjusting their own outputs,multiple units can collaborate to achieve economic dispatch objectives.However,as the intelligence and automation level of power systems continues to improve,the frequency of information exchange and data transmission involved in power scheduling processes is increasing.This highly interconnected environment also brings security threats and potential attack risks.Therefore,information security plays a crucial role in distributed power scheduling.Ensuring the security of scheduling information in distributed power systems has become an urgent problem that needs to be addressed.Also,when designing and implementing distributed power scheduling methods,it is imperative to ensure information security to guarantee the overall scheduling security of the entire power system.Proposing a Secure Consistency Protocol for Controller Structure Uncertainty in Discrete Systems.Exploring the issue of distributed consistency based on controller information protection in discrete-time multi-agent systems.From the perspective of controller dynamics,a consistency protocol based on controller information protection is being proposed,where a two-layered local controller design consists of parallel homogeneous and heterogeneous elements.By discussing the network sensitivity matrix method for the referenced discrete multi-agent system,design guidelines for a secure consistency protocol to protect controller information in discrete systems are being provided.The results indicate that the design of the heterogeneous element units in the two-layered local controller relies on a single parameter from the homogeneous element units and the norm of the folded system,and the communication network’s topology is influenced by controller parameters and the sampling period.Additionally,a parallel implementation method for the two-layered local controller is being proposed based on a bisection algorithm.Proposing the Heterogeneous Dual-Layer Local Controller Approach for Secure Power System Dispatch.Exploring the power system dispatch process,considering the environmental benefits of generator units by abstracting their cost and pollution emission functions as quadratic functions.Additionally,accounting for both network losses and communication delays in the dispatch scenario and abstracting the network loss function of generator unit output power as a linear function.Through mathematical modeling,conducting a detailed analysis of these two dispatch models and utilizing the Lagrange multiplier method to calculate the system’s incremental consistency cost,transforming the distributed economic dispatch problem into a distributed consistency problem.In simulation comparisons,evaluating the proposed distributed power system dispatch algorithm based on controller information protection against existing distributed dispatch algorithms.The results show that both algorithms yield identical economic dispatch outcomes.However,by introducing the design of a heterogeneous dual-layer local controller,the power system can achieve controller information protection,ensuring the security of distributed economic dispatch in the power system.This is of significant importance for enhancing the reliability and cost-effectiveness of the power system.
