针对分属不同利益主体的微电网构成的微电网群在隐私保护下的协同优化运行问题,提出了一种基于联邦学习的多主体微电网群协同优化运行与策略进化方法。首先,各个微电网在本地训练自身的等值封装模型并上传至云端。然后,云端汇集各微电网的等值封装模型,进行场景推演和全局策略搜索,并下发策略至各微电网。最后,各微电网通过分布式联合训练纵向联邦神经网络学习新策略,实现在隐私保护下的微电网群协同优化运行与策略进化。不同规模微电网群协同运行的仿真结果表明,该方法实现了多主体微电网群在隐私保护下的协同优化运行,相较于独立运行、非合作博弈以及多智能体深度强化学习方法,提升了微电网群整体的经济效益,并保证了各参与方利益的合理分配。
Aiming at the collaborative optimization operation problem of the microgrid cluster composed of microgrids belonging to different stakeholders under privacy protection
this paper proposes a multi-agent collaborative optimization operation and strategy evolution method of microgrid cluster based on federated learning. First
each microgrid trains its own equivalent package model locally and uploads it to the cloud. Then
the cloud collects the equivalent package model of each microgrid
performs scenario deduction and global strategy search
and issues strategies to each microgrid. Finally
each microgrid learns new strategies through the distributed joint training of vertical federated neural networks to realize the collaborative optimization operation and strategy evolution of microgrid clusters under privacy protection. The simulation results of the collaborative operation of microgrid clusters with different scales show that this method realizes the collaborative optimization operation of multi-agent microgrid cluster under privacy protection. Compared with autonomous control
non-cooperative game as well as the multi-agent deep reinforcement learning method
the proposed method improves the overall economic benefits of the microgrid cluster and ensures the reasonable distribution of the interests of each participant.
