人们普遍预计日本将在其电网中引入光伏发电。随着光伏的大规模引进,可能会出现全国范围内供需平衡的产能短缺问题。因此,我们之前报道了一个利用区块链的分散式剩余光伏输出交易系统。我们提出的系统可以找到剩余光伏输出的消费者,并通过市场机制匹配电力供需。然而,该系统没有考虑配电线路的约束。因此,我们提出了一种新的合约处理算法来计算有剩余电力交易区域的节点价格。我们讨论了将节点价格应用于现有模型所导致的配电网负荷变化,并考虑了交易流程和拟议系统的组成。
Japan is widely expected to introduce photovoltaics (PV) to its power grid. With a massive introduction of photovoltaics, the capacity shortage of balancing supply and demand associated with nationwide may arise. Thus, we previously reported a decentralized surplus PV output transaction system utilizing blockchain. Our proposed system made it possible to find consumers of surplus PV output and to match electricity supply and demand with market mechanism. However, the proposed system did not consider the constraint of the distribution line. Therefore, we propose a new contract processing algorithm to calculate the nodal price in the area where with surplus power transaction. We discuss the change in load on the distribution line as a result of applying nodal price to the existing model and consider the flow of transaction and components of the proposed system.
