The growing global energy demand has been the motivation for innovations for improved approaches on energy trade. The involvement of new energy market players known as prosumers have also enabled Peer-to-Peer (P2P) energy trade in microgrid communities. In this paper, a novel approach to energy trading based on Hive Strategy is proposed. The strategy aims to encourage prosumers to become workers that will meet the energy demands of consumers referred to as hives. The workers are selected based on their Prosumer Ratings (PR) and are ranked from the ones with the highest PR to the lowest. Using the PR, prosumers with the best energy consumption and generation behaviors are prioritized for energy trade. To test the proposed strategy, a simulation has conducted and the results show how the energy demand of the hive is met by the workers. Furthermore, an improvement in the pay-offs and PR of the workers are observed.

본 논문은 블록체인 알고리즘을 탑재한 HEMS 시스템을 활용하여 전력의 생산과 소비를 동시에 수행하는 에너지 프로슈머들 간의 안전하고 신뢰성 있는 전력거래 시스템을 구현하기 위한 방안을 연구하였다. 신재생발전원의 가정내 보급이 증대하고 HEMS를 통해 댁내 에너지관리가 보다 스마트해지고 전력정보의 실시간 취득이 가능해짐에 따라 동일 변대주 인근 배전선로와 연결된 에너지 프로슈머들간의 소규모 전력거래에 있어 블록체인 기반 기술 적용이 보다 용이해 질 것으로 예상된다. 또한, HEMS를 활용하여 블록체인 기반 P2P간의 전력거래에 있어 기술적 한계를 극복하기 위한 추가적인 연구 방향을 함께 제시하였다.

The proliferation of distributed power sources such as renewable energy sources drives the changes of consumers to prosumers who actively want to deal with energy. The prosumer is a new type of consumer that can sell surplus energy or additionally generated energy to electric power companies, other energy service providers, or other consumers. To implement such a concept, a new technology and platform that can support the transaction of the prosumers are required. However, the study in the area is limited since it is in the early stage. This work examines the state-of-the-art transaction-based energy management technology through comparative analysis of representative technologies to show the future trends. Although, technologies and standards for transaction based energy are not much matured yet. related new research will be continued via competitions.

This paper is a review of the certification system required for various energy prosumer business models, including P2P energy trading and participation in small demand response programs, which are based on reliable production and consumption certification. One of the most important parameter in energy trading is ensuring the reliability of trading account balancing. Therefore, we studied to use big data pattern analysis based blockchain smart contract between trading partners to make its tradings are more reliable. For this purpose big data analysis system collected from the IoT AMI and a production authentication system using a private blockchain network linked with the AMI is discussed, using the blockchain smart contract are also suggested. Futhermore, energy trading system concept and business models are introduced.

We estimated the price range of electricity transactions under the prosumer system, considering the spread of renewable energy and the prospect of introducing a surplus power trading system between power consumers in Korea. The range (min/max) of power transaction prices was estimated by prosumers and consumers who could purchase electricity from utilities if needed. It is assumed that utilities purchased electricity from prosumers and consumers under a Time-of-Use (TOU) rate, trading at a monthly price. The range of available transaction prices according to the amount of power purchased from utilities and the amount of transaction power was also estimated. The price range that can be traded is expected to vary depending on variables such as the TOU rate, purchased and surplus power, levelized cost of electricity, etc.

기존의 중앙 집중형 에너지 거래 방식을 블록체인 기반의 분산형 거래방식으로 변경하여 누구나 공급자나 수요자(프로슈머)가 될 수 있고, 투명하고 신뢰성 있는 에너지 거래가 이루어지도록 한다. 이러한 거래가 이루어지기 위해 공급자와 수요자를 연결하고 공급 및 수요를 효율적으로 관리하여 새로운 부가가치를 창출하는 시스템을 개발한다.
