Impacts of random household participations on a transactive open energy market in residential microgrids

The paper investigates the impacts of random household participations in a transactive open energy market (TOEM) in
residential microgrids. The strategic decision making procedures of
different households with diverse renewable energy portfolios are
analyzed by formulating a non-cooperative game for neighborhood
energy transactions. In the proposed TOEM, houses with energy excesses initiate the energy trading process while houses with energy
shortages act as followers to meet their demands by purchasing
energy at competitive prices. Moreover, there are flexibilities for
participants for energy transactions in the TOEM, i.e., individual
households are free either to participate or not. The impacts of
random participations of different households for energy trading
in residential microgrids with the TOEM are analyzed in this paper
in terms of utilities of sellers and buyers. Several case studies are
conducted using residential house level data for energy generations
and consumptions by considering Australian scenarios in order to
show how the proposed energy trading game achieves cost savings
as well as how random participations of different households affect
individual rationalities.
