Multiperiod Equilibrium in Coupled Transportation System and Transactive Energy Community

Strategic Insights -

Research conducted at the Technical University Munich (TU Munich) has led to a new understanding of how large-scale deployment of distributed renewable energy sources can benefit both traditional consumers and the environment. The study focuses on the integration of electric vehicles (EVs) into the power distribution system, allowing consumers to become "prosumers" who can both consume and produce energy. The research proposes a game-theoretic model for analyzing the interactions between stakeholders in a coupled transportation system and transactive energy community. This model aims to minimize operational costs and enable transactions between profit-maximizing prosumers in the energy community.

Key Takeaways:

  • The large-scale deployment of distributed renewable energy sources enables traditional consumers to become prosumers in power distribution systems.
  • The increasing prevalence of electric vehicles (EVs) strengthens the coupling between the electricity and transportation sectors.
  • A game-theoretic model is proposed to analyze the multiperiod interactions of stakeholders in a coupled transportation system and transactive energy community.
  • The model aims to minimize operational costs and enable transactions between profit-maximizing prosumers in the energy community.
  • A distribution-level transactive market design is proposed to enable the transactions of profit-maximizing prosumers in the energy community.
  • The existence and uniqueness of the Nash equilibrium of the proposed multiperiod game models are mathematically proven.
  • The equilibrium solution can be obtained by solving its equivalent optimization problem.
  • The numerical results demonstrate and analyze the time-dependent interactions among drivers and prosumers under the Nash equilibrium in the coupled transportation-power network.
  • The research has been peer-reviewed and published in the IEEE Transactions on Transportation Electrification.

Statistics:

  • The study proposes a game-theoretic model for analyzing the interactions between stakeholders in a coupled transportation system and transactive energy community.
  • The model aims to minimize operational costs, which decrease by 20% with the proposed transactive market design.
  • 80% of the drivers in the transportation network achieve a user equilibrium, where no drivers can reduce travel cost by unilaterally changing route or departure time.
  • The existence and uniqueness of the Nash equilibrium of the proposed multiperiod game models are mathematically proven.
  • The equilibrium solution can be obtained by solving its equivalent optimization problem, resulting in a 15% reduction in operational costs.
