The present paper considers some technical issues related to the “energy blockchain” paradigm applied to microgrids. In particular, what appears from the study is that the superposition of energy transactions in a microgrid creates a variation of the power losses in all the branches of the microgrid. Traditional power losses allocation in distribution systems takes into account only generators while, in this paper, a real-time attribution of power losses to each transaction involving one generator and one load node is done by defining some suitable indices. Besides, the presence of P-V nodes increases the level of reactive flows and provides a more complex technical perspective. For this reason, reactive power generation for voltage support at P-V nodes poses a further problem of reactive power flow exchange, which is worth of investigation in future works in order to define a possible way of remuneration. The experimental section of the paper considers a medium voltage microgrid and two different operational scenarios.

微电网中能源区块链的技术方法


本文考虑了与应用于微电网的“能源区块链”范式相关的一些技术问题。特别是，研究表明，微电网中能源交易的叠加会导致微电网所有分支的功率损耗发生变化。配电系统中的传统功率损耗分配仅考虑发电机，而在本文中，通过定义一些合适的指数来将功率损耗实时归因于涉及一台发电机和一个负载节点的每笔交易。此外，光伏节点的存在增加了反应流的水平，并提供了更复杂的技术视角。因此，光伏节点电压支持的无功发电提出了无功潮流交换的进一步问题，这值得在未来的工作中进行研究，以确定可能的补偿方式。本文的实验部分考虑了中压微电网和两种不同的运行场景。
