Abstract: Aiming at day-ahead power and heat combined dispatch problem of microgrid containing renewable energy, a comparative analysis on optimization results of global optimization and multi-agent game is carried out. Initially, on the basis of efficiency model of energy generation and conversion equipment in multi-energy microgrid, considering life loss of energy storage, renewable energy curtailment, dispatch cost of electric vehicles, etc., operating cost models of various equipment are established. Furthermore, mathematical model of day-ahead economic dispatch aiming at microgrid has the best operating cost is established, and an advanced chaotic particle swarm optimization algorithm based on particle dimension entropy is established. Additionally, mathematical day-ahead economic dispatch model of multi-agent interest balance is established, which contains renewable energy owner, microgrid energy service provider and user. And a solve method based on Nash equilibrium game is proposed. Finally, in-depth comparative analysis is carried out according to the economic dispatch results of global optimization and multi-agent game, and the validity and practicability of the model are illustrated.
