双链存储的微电网分级电能交易策略

在微电网电能交易中，传统的方法是通过单链区块链技术存储电能交易模型内部数据，但是模型需要较大的存储空间。为了节约微电网交易系统的存储资源，采用物理区块链和交易区块链双链存储结构的方法储存微电网电能交易模型的数据，有效解决了单链储存情况下存储数据的冗余问题，节约了数据的存储成本。在微电网电能交易策略上，目前多采用双向拍卖机制进行电能交易，电能交易采用供需平衡方式进行交易。考虑到微电网内不同类型的分布式电源和负荷的差异，应用博弈论方法对微电网电能竞价策略进行分析，在满足供需平衡的条件下，对微电网的分布式电源和负荷按照各自利润最大化为目标进行优化，优化了微电网电能交易策略，使得分布式电源获得可观的利润。最后，通过具体微电网实验算例分析验证了该交易策略的有效性。

Micro-grid Hierarchical Energy Trading Strategy Based on Double Blockchain Storage

In micro-grid electric energy transaction, the traditional method is to store the internal data of electric energy transaction model through single chain block chain technology, but the original model needs large storage space. In order to save the storage resources of micro-grid trading system, this paper uses the method of physical block chain and transaction block chain double chain storage structure to store the data of micro-grid electric energy trading model. It effectively solves the stored in single chain storage is effectively solved and the storage cost of data is saved. In the electric energy trading strategy of micro-grid, two-way auction mechanism is used to trade electric energy, and supply-demand balance is used to trade electric energy. Considering the difference of different types of distributed power supply and load in micro-grid. This paper uses game theory method to analyze the power bidding strategy of micro-grid, under the condition of satisfying the balance of supply and demand. The distributed power supply and load of micro-grid are optimized according to their profit maximization. Finally, the effectiveness of the trading strategy is verified by an experimental example of micro-grid.
