摘要
基于区块链技术的能源交易体系能够有效解决传统集中资源配置带来的效率低下、隐私安全等问题,而能源互联网中大量能源主体间频繁的能源交易会产生大量的交易记录,使能源链变得更长,同时增加了各能源主体间的能源传输成本。基于此,研究了区块链视角下各能源主体的储能优化配置模型,通过配置合适的储能尽可能地实现自给自足。若能源主体有足够的剩余电力则作为卖方出售给其他缺能主体,这样不仅减少了频繁进行能源交易造成的能源浪费以及高额成本,也提升了区域能源的自给自足能力,还减少了能源数据冗余。以IEEE 33节点系统为例,验证了所提资源配置模型的有效性。
The energy transaction system based on blockchain technology can effectively solve the problems of low efficiency and privacy security brought by traditional centralized resource allocation,while frequent energy transactions among a large number of energy entities in the energy internet will generate a lot of transaction records,which makes the energy chain longer and increases the energy transmission costs among energy entities.Based on this,the optimal allocation model of energy storage from the perspective of blockchain is proposed for each energy entity,which realizes self-sufficiency as much as possible by allocating appropriate energy storage.If the energy entity has enough surplus electricity,it will be sold to other energydeficient entities as a seller,which not only reduces the energy waste and high cost caused by frequent energy transaction,but also improves the self-sufficiency level of regional energy,and reduces the redundancy of energy data.Taking IEEE 33-bus system as an example,the validity of the proposed resource allocation model is verified.
