A microgrid is a group of renewable and conventional sources and loads connected to the
main utility grid. Such a microgrid helps consumers to have a reliable and high-quality power
source. The number of microgrids connected to the utility distribution grid significantly grows
due to the increasing power demand and the rapid adoption of renewables. In a group of
microgrids, a microgrid may have excess power available through renewable energy sources
that can be provided to the power grid. A microgrid with an energy deficit connected to the
system can buy the excess power from another microgrid. A prosumer is one of the essential
components in microgrid who can buy and sell electrical energy. As renewable energy sources
such as rooftop solar and wind turbines become affordable, many consumers are installing
renewable sources to reduce their electricity bills. Therefore, the number of prosumers has
been gradually increased in the system.
Advancements in information and communication technology (ICT) have increased the
ability the peer-to-peer (P2P) transactions in modern power systems. When two participants
agree on the P2P energy transactions, they can plan to use the existing electrical distribution
system to complete the transaction. Such energy transaction reduces the power stresses on the
main utility grid, making the utilities advantageous. However, the stresses and losses
associated with the transaction should be taken into account. The proposed thesis aims to
develop a pricing framework for transactions between participants to promote a liberalized
energy market. This framework achieved by predicting the losses during the energy
transactions and other system stresses, such as voltage and frequency drops. The necessary
corrective actions enabled these transactions, and their cost is calculated to form the pricing
basis for the energy transactions. In addition, an intelligent system with advanced calculation
methods is proposed to address the requirements of handling multiple transactions
simultaneously.
