Summary: This paper proposes a novel peer-to-peer control strategy (PPCS) and develops a generalized hierarchical control scheme (GHCS) based on PPCS for DC voltage control and power sharing in multi-terminal DC distribution systems (MTDCDSs). The PPCS eliminates the mode switching of the voltage source converter (VSC) and achieves three objectives simultaneously. The GHCS is simple and easy to implement, and its optimal operation and satisfactory performance are demonstrated theoretically and validated through hardware-in-the-loop (HIL) tests in a +/- 10 kV MTDCDS.

Summary: This paper introduces a hierarchical concurrent optimistic blockchain consensus protocol (HiCoOB) to improve the performance and scalability of blockchain-based peer-to-peer energy trading systems. The protocol enables parallel processing of local and global transactions, reduces the burden on local nodes, and achieves higher throughput and lower latency. Experimental results demonstrate an 87% increase in throughput, a 5x reduction in waiting time for local transactions, and a 10x reduction in message exchange overhead for local leader nodes.

Summary: After a long period of stability in the electricity industry, extensive deployment of distributed energy resources and advancements in computation and communication technologies have led to a transition in the power system from a traditional hierarchical structure to a more decentralized model. While the effectiveness of P2P sharing has been demonstrated in various studies and pilot projects, there are still challenges to be addressed for its widespread implementation in today's electricity markets.

Summary: The paper proposes a novel decentralized competitive energy system to facilitate the utilization of locally-produced energy and achieve supply-demand balance. Through a multi-layer system architecture and a money transaction protocol based on IOTA among devices, the peer-to-peer heating system outperforms conventional central heating systems in terms of user cost and system efficiency, as demonstrated by a case study and computer simulations.

Summary: The paper proposes a two-stage peer-to-peer energy trading model that considers the role of the utility. In the first stage, energy transactions between buyers and sellers are optimized; in the second stage, cleared transactions are submitted to the utility for approval to verify transactions and ensure compliance with various network constraints.

Summary: This study presents peer energy trading management approaches in a net-zero energy community by analyzing actual energy consumption and simulation data for university campus, commercial office, and high-rise residential building groups. The use of an individual peer energy trading price model and time-of-use trading management strategies improved renewable energy self-consumption ratio and load cover ratio in the community.

Summary: This study introduces an approximate semantic publish/subscribe system based on a content-based approach, proposing a hybrid event routing model that utilizes a high-dimensional semantic vector space. Experimental results show that rendezvous-based routing achieves up to 54% recall with a 44% decrease in messaging overhead, while the hybrid routing approach achieves up to 43.8% recall with a 59% reduction in messaging overhead.

Summary: This paper explores optimal energy management in dwellings with micro fuel cell combined heat and power systems, introducing a peer-to-peer energy trading system to enhance self-sufficiency and resilience. By utilizing a distributed ADMM approach and linearization method, the non-convex optimization problem is efficiently solved, demonstrating the system's performance and positive impacts through a case study with realistic data. The approach shows fast convergence and scalability, while the P2P trading system helps improve fuel cell efficiency and dwelling self-sufficiency.

Summary: This study investigates the peer-to-peer trading price and strategy in a residential microgrid based on market-driven methods. Five cases are proposed considering different market types, tariff systems, and pricing models. The results show that the individual pricing model leads to dynamic P2P electricity trading prices and P2P trading is more economically efficient under the time-of-use tariff system.
