Discrete Adiabatic Variation Quantum Power Flow Calculation Method for Power Systems
摘要
Abstract
The scale of modem power systems is rapidly increasing,creating an urgent need for high-performance computing to facilitate more efficient and intelligent energy distribution and management.Quantum computing has great potential for addressing these complex problems.Future computational demands of power networks are expected to benefit significantly from advancements in quantum computing.Therefore,this paper proposes a discrete adiabatic variational quantum flow calculation method for power systems.Firstly,a quantum flow calculation model is constructed using the discrete adiabatic quantum computing method.Then,a scheduling function f(s)is selected to obtain the discrete adiabatic evolution sequence,bringing the discrete adiabatic quantum flow calculation closer to the ideal adiabatic evolution process.Next,unitary matrix classification is employed to rapidly deploy matrix information to the quantum computer,and a variational quantum algorithm is used for solving.Finally,the algorithm's effectiveness is tested on a quantum simulator using the IEEE 14-bus system and real power grid data.The results show that the proposed method uses fewer quantum resources and can complete flow calculation tasks with an error margin of less than 1％.关键词
