摘要

多微电网间分布式交易可促进新能源的消纳,提高配电网运行的安全性。然而其个体趋利性强和出力不确定性等问题可能使交易主体发生严重违约行为,影响分布式电能交易的经济性。因此,提出计及信誉值和电气距离的多微电网分布式电能交易区块链模型。首先,针对分布式电能交易中存在的违约行为,提出基于合约完成率的信誉值评估模型,并结合其报价信息调整购售电主体的交易次序。其次,为促进交易主体选择就近交易和提高交易效率,在智能合约中设计了计及电气距离的交易撮合机制,并提出根据市场进程和自身信誉情况的报价更新策略。再次,为实现配电网运行的安全性,在交易撮合过程中引入了实时动态网络安全校核方法。最后,基于Matlab和IDE-Remix平台对智能合约进行仿真分析,算例结果证明了所提分布式交易机制的合理性和有效性。

Abstract

Distributed transactions between multiple microgrids can promote the consumption of new energy and improve the safety of distribution network operation. Nevertheless, the problems such as strong individual profit-seeking and output uncertainty may cause serious breaches of contract and affect the economics of distributed transactions. Therefore, this paper puts forward a distributed energy transaction blockchain model considering reputation value and electrical distance. Firstly, the reputation value evaluation model based on the historical contract completion rate is proposed, and the transaction order of buyers and sellers is adjusted according to the quotation and reputation value. Secondly, in order to promote transaction subjects to choose nearby transactions and improve transaction efficiency, a transaction matching mechanism based on electrical distance is designed in smart contracts. And an adaptive quotation update strategy based on market progress and its own reputation are proposed. Thirdly, a real-time dynamic network security checking method is introduced to realize the safety of distribution network operation. Finally, the smart contract is simulated and analyzed with Matlab and IDE-Remix platform, and the results verify the feasibility and effectiveness of the proposed distributed transaction mechanism.

In this paper, we investigate the problem of credit rating management in energy trading among microgrids subject to transmission losses and wheeling cost. The main concern is how to constrain the default behaviors of retailers to enable all the consumers and retailers to be actively involved in the energy trading. By endowing retailers as leaders and consumers as followers, we establish a multi-leader multi-follower dynamic game model and propose a scorecard model based on logistic regression to evaluate retailers' credit ratings. The concept of trust degree is then introduced for all the retailers as a punitive measure to relate their credit ratings with the reduction in the profit. With such a strategy, we can theoretically show that a unique equilibrium exists for the dynamic game model. Moreover, a best response algorithm is proposed to make the consumers and retailers achieve the equilibrium iteratively. Numerical simulations are provided to demonstrate the effectiveness and efficiency of the proposed method. It is found that default behaviors of selfish retailers can be greatly constrained with only a slight degradation of the interests of other participants, thereby promoting the establishment of a trustworthy trading market. We also discuss the influence level of transmission losses on trading behaviors of retailers and consumers.

摘要

随着光伏（photovoltaic，PV)发电的大力发展和上网补贴的逐步下调，就近消纳的优势得以显现，这促进了分布式发电的市场化交易 (market trading for distributed generation, MTDG)。MTDG的发、用电双方都在电网末端，具有参与主体数量大、单笔交易规模小、点对点等特点。传统的中心化交易模式存在透明度低、成本高、效率低下、数据不可信等问题，不适合MTDG。区块链技术具有去中心化、不可篡改、匿名等特点，满足MTDG的需要，能够提升这种交易的安全性、自主性、透明性等。在此背景下，文章将区块链技术引入MTDG，针对MTDG的特点，构建了相应的交易机制、结算机制和奖惩机制。最后，采用算例对所发展的MTDG机制进行了说明。

With the rapid development of photovoltaic (PV) power generation and the gradual downward subsidies, the advantages of satisfying load demand by local generation supply are becoming more and more significant, and market trading for distributed generation (MTDG) is then promoted. In MTDG, both power generation and load demand are located at the end of the utility grid, with some features exhibited including numerous participating entities, small transaction sizes, and point-to-point transactions. The traditional centralized transaction model suffers some problems such as low transparency, high cost, low efficiency, and untrustworthy data, and is not suitable for MTDG. Blockchain technology has the characteristics of decentralization, non-tampering, and anonymity, and can well meet the needs of MTDG for improved security, autonomy and transparency of electricity transactions. Given this background, the blockchain technology is applied in MTDG, and the corresponding trading mechanism, settlement mechanism and reward and punishment mechanism are developed considering the characteristics of MTDG. Finally, an example is employed to demonstrate the developed MTDG mechanism.
