Value creation and sharing methods in household energy communities

Energy community creates value by aggregating the demand and supply profiles of neighbouring prosumers. The value must be shared fairly while not discouraging new members from joining the energy community. This paper presents an approach for modelling the value of energy community as well as several value sharing methods. A model energy community is simulated based on a yearlong historical data of six household prosumers. The energy community was investigated in terms of self-sufficiency, self-consumption and value cause distribution. The case study highlighted the drawbacks of conventional value sharing methods. An adjusted marginal contribution or Shapley methods are suggested to provide most fair and practical value distribution.
