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P2P能源交易的技术方法

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。特别地，从研究中可以看出，微电网中能量交易的叠加会在微电网的所有分支中产生功率损耗的变化。配电系统中传统的功率损耗分配只考虑了发电机，而在本文中，通过定义一些合适的指标来将功率损耗实时分配给涉及一台发电机和一个负载节点的每笔交易。此外，PV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，用于P–V节点电压支持的无功功率产生了无功功率交换的另一个问题，为了确定可能的薪酬方式，这值得在以后的工作中进行研究。本文的实验部分考虑了中压微电网和两种不同的运行方案。
