Two-layer Robust Planning of Urban Integrated Energy Station Based on Multi-agent Safe Reinforcement Learning
To address challenges including load uncertainty and complex geographic information faced in the siting and sizing planning of urban integrated energy stations
this paper proposes a two-layer robust planning method based on multi-agent safe reinforcement learning. Firstly
a two-layer planning framework for the siting and sizing of urban integrated energy stations is constructed. At the upper level
based on the location set-covering model
the spatio-temporal characteristics of multi-energy loads and geographic information system data are integrated to optimize the siting strategy of urban integrated energy stations with the objectives of optimal economy and coverage efficiency. At the lower level
considering the multi-stage construction sequence
the multi-stage sizing and operation strategies of equipment are optimized to minimize the full-life-cycle cost. Secondly
a multi-agent safe proximal policy optimization algorithm is proposed to tackle complex high-dimensional uncertainty problems in the planning process. By introducing a value constraint network
the proposed algorithm guides the optimization policy into the safe feasible region. The augmented Lagrangian method is adopted to transform the constrained optimization problem into an unconstrained one
where agents adaptively learn robust optimization policies in uncertain environments. Finally
numerical cases are carried out based on a real-world city. Simulation results demonstrate that the proposed model and algorithm outperform conventional methods in terms of economic performance
computational efficiency
and robustness against long‑term load-growth uncertainty
and can provide effective decision-making support for urban energy system planning.
