Design And Implementation Of Communication Protocol Supporting Energy Exchange In Software Defined Architecture

Energy Internet is an energy interconnection and sharing network,which is supported by information and communication technology,which can effectively accommodate large-scale and distributed clean energy.Energy Internet is the future form of the power grid.In Energy Internet,the wide deployment of intelligent electronic devices has generated a huge amount of data.Distributed renewable energy generator and energy storage device are widely connected to the power grid,exchange a lot amount of information and energy.The improvement of power trading market also promotes the development of energy trading.In this scenario,the free exchange of energy will be a major feature of Energy Internet.Based on the features of energy exchange business in Energy Internet,this paper presents a communication protocol which supports energy exchange in the software defined architecture.The protocol is extended based on the IEEE 1888 protocol,supporting multiple methods of operation.This protocol has the advantages of flexibility,efficiency,and extensibility,which can support the complex and changeable energy exchange business in Energy Internet.Then this paper proposes a Stackelberg game model to describe the gaming process between users and power supplier in Energy Internet.The model takes into account the effect on power supplier's profit from economic power and electricity prices.The optimization model can draw the optimal economic power and the optimal time-of-use price of each time interval.The calculation results can be used to guide the price setting for the power supplier.In this paper,the optimization model is deployed as an application of the energy management platform and then tested,further verifying the feasibility of the proposed protocol.
