  • Energy trading in the transaction zone configured in this manner has no significant effect on other zones in terms of power flow because only little power flow passes through the branch, which is connected in adjacent to the transaction zone

Summary

Introduction

Distributed generation based on renewable energy is rapidly spreading worldwide. Most distributed generators with small size capacities are generally connected to a distribution network. Prosumers conventionally arrange a fixed-price contract with a utility in the form of the power purchase agreement or subscribe a net metering tariff This monolithic transaction scheme is considered a critical barrier in spreading distributed generation and establishing decentralized and autonomous trading environment [2]. To consider network constraints in power trading, Greve et al [7] suggested an energy trading method based on high computing power and real-time reconfiguration This method is performed by setting an optimum trading combination in accordance with bids and offers and repeatedly examining the constraints in the network for combination. This transaction scheme seems difficult to be applied in the present distribution network because it uses high technology, such as real-time network configuration and high computing power.
