基于区块链的智能电网分布式资源管理研究

针对智能电网中分布式能源系统存在的管理困难,电力资源难以调度等问题,提出了一种基于区块链技术的电力网络管理系统。使用以太坊作为开发平台,建立分布式能源的电力交互管理区块链。使用股权证明(PoS)变异算法确立区块链中发用电双方共识机制,指定交易双方中的记账人;通过K-means聚类算法和粒子群优化算法(PSO)来设计分布式电能调度策略,进一步保障电网中能源交易分配的可靠性,最终实现电力运营智能合约下分布式能源的有效管理。实验结果表明:在智能电网中部署电力交互管理区块链,有效解决了分布式能源交易难达成,耗时长的问题,提高了电网中资源管理的合理性。

Allocation of congestion relief cost based on flow change on the congested facilities

Congestion management in an electricity market is introduced in this paper and a new method of allocating congestion cost to transactions is proposed. The proposed method is a two-step process, in which the total congestion cost is firstly allocated to congested facilities and then to each transaction involved. The cost of relieving a congested facility allocated to each transaction is proportional to the power flow change on the congested facility caused by the transaction. The more the power flow change is on the congested facility caused by the transaction, the deeper the degree of involvement by the transaction. Therefore, cutting down the magnitudes of such transactions contributes to relieving congestion. Test results on a 5-bus system indicate that the proposed method can reflect reasonably the degree of involvement by each transaction in the congestion and provide correct price signals contributing to relieving congestion.
