Abstract:
Increased penetration of renewable energy-based plug-able and Distributed Energy Resources
(DER) brings new challenges to distribution systems. To address these changes, the power system
experts promote Transactive Energy (TE) models. Transactive Energy is a concept of providing
control over energy exchange by integrating electricity markets and auction mechanisms. Numbers
of studies on TE have shown a positive effect of TE management systems on distribution system
efficiency, security, and reliability. However, it is still difficult to suggest TE model that will
consider majority of distribution network constraints. The constraints include power allocation,
voltage stability, network losses, congestion constraints and others. In the past Optimal Power
Flow (OPF) method was used for distribution system management. Therefore, this thesis
concentrates on modelling and simulation of feasible TE framework. In addition, more attention
will be given for energy scheduling utilizing Distribution Locational Marginal Price (DLMP). The
DLMP is key parameter that determine true cost of energy accounting topology, power losses,
congestion, and other parameters. Therefore, this work will examine DLMP based Transactive
Energy framework for distribution systems with enthusiastic or smart prosumers. The framework
uses MAS as the basis on which the proposed Transactive Energy (TE) model, i.e. DLMP based
TE Management System (DTEMS), is implemented. DTEMS uses a novel metric known as nodal
earning component, which is determined by the optimal power flow (OPF) based smart auction
mechanism, to schedule the TE transactions optimally among the stakeholders by alleviating the
congestion in the distribution system. Based on the individual contributions to the congestion
relief, DTEMS ranks the prosumers and loads as Most Valuable Players (MVPs) and assigns the
energy trading price according to the category of the player. The effectiveness of the proposed TE
model is verified by simulating the proposed DTEMS for a modified 33 bus radial distribution
system fed with various plug-able energy resources, prosumers, and microgrids.
