Lightweight Energy Management Strategy for Cloud-Edge Collaborative Virtual Power Plants
The virtual power plant (VPP) aggregates massive distributed resources to form a large-scale market entity interacting with the power grid. However
the energy management of large-scale distributed resources faces a contradiction between global optimization and local demands. Centralized optimization and regulation struggle to balance electricity costs and comfort of the users
while local user energy management lacks coordinated control over the overall operational state of the VPP. Therefore
a lightweight user energy management strategy for cloud-edge collaborative VPPs is proposed. Firstly
a hierarchical decision-making framework for energy management of VPPs is constructed to shift unidirectional control to bidirectional interaction. Secondly
considering the limited computational resources of low-cost edge devices
a local decision-making algorithm based on sparse reinforcement learning is proposed
which uses adaptive topology evolution to reduce the number of trainable parameters in neural networks. Finally
case studies conducted on real-world datasets validate the effectiveness and efficiency of the proposed lightweight strategy.
