The increase in the penetration of renewable energy generation technologies at the household level has led to the development of local energy trading. The local energy trading within a community reduces the dependency of the community on the main grid and reduces the electricity bill of the consumers. This paper proposes a pair matching methodology within the local energy market for the energy buyers and sellers. Firstly, the pair matching methodology maximizes the surplus power to be shared by considering the network constraints at the seller‟s premises. Secondly, the sharing pairs are identified between the sellers and buyers taking into the account of congested lines. Thirdly, the best sharing pairs are recommended by the local aggregator based on the network parameters. The proposed methodology is tested using a benchmark low voltage microgrid network. © 2020 Alpha Publishers.

Pair matching methodology for local energy markets

The awareness of self-consumption of grid-connected roof-top solar photovoltaic (PV) owners in a community and the advancement in information and communication technologies (ICT) led to the development of a novel peer-to-peer energy trading mechanism for next-generation power systems. In the peer-to-peer (P2P) energy trading landscape, the prosumers and consumers self-organize and trade energy among themselves. In recent years, the large penetration of distributed energy resources, as well as the advancement of technologies in the fields of protection, power electronics, and storage devices, led to the use of direct current (DC) home appliances by the end-users, i.e., consumers in a community. In this paper, the operational costs of an individual household and community when operated with alternating current (AC) and DC home appliances are calculated using bill sharing and the mid-market rate method for various degrees of PV penetration. The bill sharing method shares the operational cost and income among all the peers in proportion to the amount of energy they consume/generate. The mid-market rate method calculates the P2P internal price at the median of the import and export price based on the relationship between total generation and demand. In terms of operational cost, both producers and consumers benefit fairly when the mid-market rate method is used when the households in a community are operated with DC home appliances.

Restructured power system helps to meet the active power requirements of the consumers in an effective way. In an Independent System Operator (ISO) model of restructured power system, Available Transfer Capability (ATC) is calculated so as to determine how much extra power can be injected into one site apart from base consumption. ATC computation plays a significant role during power transactions because it helps the participants to schedule their transaction more effectively and quickly. This paper mainly focuses on ATC calculation using linear sensitivity factors for normal mode and line outage mode. © 2017 The Authors. Published by Elsevier Ltd.
