摘要
新型电力系统发展亟需安全高效的电力边缘通信网络支撑。现有工作重点讨论了区块链技术在电力通信网的应用模式,但未考虑区块链引入电力通信网引起的传输性能恶化问题。对此,提出一种面向区块链电力接入网的边缘计算资源分配策略。首先,提出一种基于区块链资源管理架构,以最小化网络时延为目标构建联合虚拟机资源分配与通信资源调度模型;其次,针对优化问题为混合整数非线性规划,提出一种基于广义Benders分解的计算资源优化算法获取问题最优解。仿真算例表明:所提算法在不同用户请求任务需求及计算资源不足时有效削减计算任务处理时延,解决了区块链应用在电力通信网导致通信质量下降的问题。
The development of new power system urgently needs the support of safe and efficient power edge communication network.The existing work focuses on the application mode of blockchain technology in the power communication network,but does not consider the transmission performance deterioration caused by the introduction of blockchain into the power communication network.In this regard,an edge computing resource allocation strategy for blockchain power access network was proposed.Firstly,a blockchain-based resource management architecture was introduced to build a joint virtual machine resource allocation and communication resource scheduling model with the goal of minimizing network delay;secondly,for the optimization problem of mixed integer nonlinear programming,a computational resource optimization algorithm based on generalized Benders decomposition was proposed to obtain the optimal solution of the problem.The simulation example shows that the proposed algorithm effectively reduces the processing delay of computing tasks when different users request tasks and when computing resources are insufficient,and solves the problem that the application of blockchain in the power communication network leads to the degradation of communication quality.
