The new potential of Distributed Energy Resources (DER), residential consumers, buildings, and prosumers in terms of controllable devices, self-generation, and storage makes them more active in the market encouraged by lower electricity prices. In addition, integrating a higher volume of volatile Renewable Energy Sources (RES) that unstress the public grid by local trading interactions is a desirable target of Local Electricity Markets (LEM). In this paper, we propose a blockchain trading mechanism to simulate the electricity transactions for 11 modern smart houses with more than 300 appliances, 8 roof- or faced-PV systems, and smart-metered 15-min readings that form a small-size community. The electricity generated at the community level lowers the electricity bills and brings benefits for prosumers (sellers) and consumers (buyers). Several trading mechanisms for LEM transactions including auctions such as Uniform Price (UP), Pay-As-Bid (PAB), Generalized Second-Price (GSP), Vickrey-Clark-Groves (VCG) methods are implemented to evaluate the benefits and show their efficiency. After the market is initially cleared, an adjustment coefficient of the price is proposed for both sides (seller and buyer) to enlarge the trading potential at the community level using blockchain technology. It proves to bring excellent results to the LEM participants and enhance trading with outstanding benefits.

就可控设备，自发电和存储而言，分布式能源（DER），居民消费者，建筑物和生产者的新潜力使其在电力价格较低的鼓舞下更加活跃。此外，集成更多的挥发性可再生能源（RES），以通过本地贸易互动缓解公共电网压力，这是本地电力市场（LEM）的理想目标。在本文中，我们提出了一种区块链交易机制来模拟11个现代化智能房屋的电力交易，这些房屋具有300多个设备，8个屋顶或面对式光伏系统以及智能计量的15分钟读数，形成一个小型社区。在社区一级产生的电力降低了电费，并为生产者（卖方）和消费者（买方）带来了好处。实施LEM交易的几种交易机制，包括拍卖，例如统一价格（UP），按需付款（PAB），广义第二价格（GSP），Vickrey-Clark-Groves（VCG）方法，以评估收益并展示他们的效率。最初清除市场后，建议双方（卖方和买方）的价格调整系数，以使用区块链技术扩大社区一级的交易潜力。事实证明，这为LEM参与者带来了出色的成绩，并以显着的优势促进了交易。建议双方（卖方和买方）调整价格系数，以利用区块链技术扩大社区一级的交易潜力。事实证明，这为LEM参与者带来了出色的成绩，并以显着的优势促进了交易。建议双方（卖方和买方）调整价格系数，以利用区块链技术扩大社区一级的交易潜力。事实证明，这为LEM参与者带来了出色的成绩，并以显着的优势促进了交易。
