A P2P-Dominant Distribution System Architecture

Abstract

Peer-to-peer interactions between small-scale energy resources exploit distribution network infrastructure as an electricity carrier, but remain financially unaccountable to electric power utilities. This status-quo raises multiple challenges. First, peer-to-peer energy trading reduces the portion of electricity supplied to end-customers by utilities and their revenue streams. Second, utilities must ensure that peer-to-peer transactions comply with distribution network limits. This paper proposes a peer-to-peer energy trading architecture, in two configurations, that couples peer-to-peer interactions and distribution network operations. The first configuration assumes that these interactions are settled by the utility in a centralized manner, while the second one is peer-centric and does not involve the utility. Both configurations use distribution locational marginal prices to compute network usage charges that peers must pay to the utility for using the distribution network.

Risk Evaluation of Distribution Networks Considering Residential Load Forecasting with Stochastic Modeling of Electric Vehicles

“…The next important parameter to estimate realistic EV charging pattern is battery initial SOC, which is obtained by PDF of daily driving mileage as expressed in Equation (21). The initial battery SOC depends on driving mileage per day and it is considered that EV SOC descents linearly with travelling mileage, expressed as…”

“…where D m is daily driving mileage obtained from (21), and maximum EV range is presented by D R . PDF of initial SOC of an EV battery after 1-day mileage can be obtained by using Equation (25) and (21) based on transformation theorem of the random variable, formulated as:…”

A transactive energy management system for future community needs

“…Introduction storage units at the corresponding node. Kim et al [153], has proposed a P2P market considering power losses, where costs are allocated to each trade based upon its grid usage. A graph-based loss allocation framework is proposed in [154] for transactive energy markets in distribution systems.…”

“…On the other hand, [152][153][154][155] propose different approaches for losses and associated cost allocations but have not studied its impact on the market outcome.…”
