Economic Dispatch Strategy for Multi-Distribution Grid Units Based on MADDPG Algorithm

In order to deal with the uncertainty of source and load and improve the ability of power complementarity, this paper proposes an economic dispatch strategy for multi-distribution grid units based on MADDPG. Firstly, an economic dispatch model of multi-distribution grid units is proposed, and a mathematical model with the overall operating cost minimization as the objective function is constructed. Secondly, in order to match the goal and structure of the multi-distribution grid units system, this paper constructs the state space, action space and designs the reward function for agents. Finally, according to the simulation experimental results, the proposed method can adapt to the uncertainty of source and load and realizes the power coordination and complementarity of multi-distribution grid units and improves the reliability of power supply.
