Description

Peer-to-peer (P2P) energy sharing involves novel technologies and business models at the demand-side of power systems, which is able to manage the increasing connection of distributed energy resources (DERs). In P2P energy sharing, prosumers directly trade energy with each other to achieve a win-win outcome. A research paper titled "Evaluation of peer-to-peer energy sharing mechanisms based on a multiagent simulation framework" has been published on Applied Energy regarding this topic. In the paper, a general multiagent framework was established to simulate P2P energy sharing, with two original techniques proposed to facilitate simulation convergence. Furthermore, a systematic index system was established to evaluate P2P energy sharing mechanisms from both economic and technical perspectives.

In case studies of the paper, two sets of cases were conducted to validate the proposed simulation and evaluation methods and to give some practical implications on applying P2P energy sharing in Great Britain (GB) at present and in the future. The household demand dataset and electric vehicle (EV) dataset used in the paper has been provided for researchers to reproduce the results in the paper or to conduct further related studies. Also, the original numerical data of the results in the case studies of the paper have been provided, for researchers to better understand the results or to use the results for other purposes.

The whole dataset includes 9 excel files in total. The
detailed description for them are presented as follows:

1. “CREST_Demand_Model_v2.2 (Great Britain).xlsm” is a
high-resolution stochastic integrated thermal-electrical domestic demand
simulation tool developed by Centre for Renewable Energy Systems Technology
(CREST) of Loughborough University (refering to
http://www.lboro.ac.uk/research/crest/demand-model/). It contains a lot of
sheets and VBA codes, which are used to generate “fake” demand curves of
domestic customers sampled from statistical distributions that are based on
real-life data. In the “Main Sheet”, input parameters like “day of month”, “month
of year”, “latitude”, “longitude”, etc. can be entered, and then the “Run simulation”
button can be clicked to start the simulation. After the simulation, daily curves
like “occupancy and activity”, “total electrical demand”, “total gas demand”,
etc. are generated and visualized, with very high time resolution.

2. “Electric_Vehicle_Dataset (Great Britain).xlsx” is a
dataset based on the research conducted jointly by Centre for Integrated
Renewable Energy of Cardiff University and Key Laboratory of Smart Grid of
Ministry of Education of Tianjin University (referring to
https://doi.org/10.1016/j.apenergy.2015.10.159). It contains two sheets, which provide
the parameters of 1000 typical electric vehicles of Great Britain respectively.
For each electric vehicle, the parameters include: (1) “Time starting charging
/ returning home (hour)”, (2) “Time finishing charging / leaving home (hour)”,
(3) “Battery capacity (kWh)”, (4) “Energy consumption due to travel (measured
by SOC)”, (5) “Lowerlimit of SOC”, (6) “Upperlimit of SOC”, (7) “Maximum
charging/discharging power”, (8) “Charging efficiency”, and (9)
“Discharging efficiency”.
