Power Trading Mode in Multi-Microgrids with Controllable Distributed Generation: A Game-Theoretic Approach

摘要

This paper proposed a non-cooperative game-theoretic method to study power trading modes and strategies in multi-microgrids system (MS) including controllable distributed generation (DG). Considering the influence of DG on MS trading strategy decisions, a strategic game-theoretic model was put forward under the system trading rules. The effects of the distribution system (DS) on microgrids trading were regarded as service charges. The existence of Nash Equilibrium (NE) and the feasibility of the proposed trading method among MS were validated mathematically. A three-microgrid case was introduced to verify the practical significance of NE and the simulation results have demonstrated that the power generation cost of DG will not effect the system equilibrium.
