Virtual power plant aggregation regulation and control communication network flow balancing method and device

Abstract

The invention discloses a virtual power plant aggregation regulation and control communication network flow balancing method and device. The method comprises the following steps: generating a slice network mapping scheme based on slice node, slice link and slice gateway mapping; and carrying out iterative optimization on the slice network mapping scheme by adopting an improved biogeography principle algorithm to obtain an optimal mapping scheme. Through implementation of the method, a plurality of slice network mapping schemes are generated to serve as a population for improving a biogeography principle algorithm, meanwhile, the population and a migration operator are reset, the earlier-stage tentative search capability and the later-stage better convergence speed are increased, iterative optimization is performed on the initial mapping scheme population, SDN-defined network slice global optimization is performed, and the algorithm efficiency is improved. The invention discloses slice network mapping used for virtual power plant communication network flow balancing, which balances the flow of the whole physical network, reduces virtual power plant communication network congestion and network transmission delay, and improves network transmission real-time performance and network long-term average operation benefit and effectiveness maximization.

Description

technical field [0001] The invention relates to the technical field of communication in virtual power plants, in particular to a method and device for balancing traffic in a virtual power plant aggregation regulation and communication network. Background technique [0002] The communication network is an important support for the aggregation control of the virtual power plant. The application of the aggregation communication gateway realizes the access of massive heterogeneous service terminals, and completes the access and processing of the corresponding virtual power plant integrated service applications. Due to the constraints of real-time business requirements and limited computing resources, it is necessary to aggregate communication gateways and cloud platforms for collaborative computing to achieve business functions. Most of these data collection devices are unattended and work continuously for a long time, which will inevitably generate massive amounts of data. In t...
