In the context of constructing a new-type power system dominated by renewable energy
this study introduces an electricity-carbon coupling operational decision-making mechanism for photovoltaic power generation clusters. The goal is to fully utilize the potential of large-scale grid-connected photovoltaic power generation in supporting energy conservation and carbon reduction
while also enhancing the operational efficiency of power systems through the unified management of photovoltaic power stations. The design and theoretical analysis are concentrated on three key aspects: 1) Photovoltaic cluster partitioning methods that consider electricity-carbon indicators; 2) The construction of a critical path analysis model for the impact of photovoltaic clusters on system electricity-carbon indicators; 3) The establishment of an efficiency decision-making framework for electricity-carbon coupling operations within photovoltaic cluster models. Finally
the paper outlines future research priorities. The proposed approach establishes a foundation for analyzing how photovoltaic clusters can support low-carbon operational efficiency
provides analytical methods to clarify carbon emission responsibilities across operational stages and identify management weaknesses
and offers a reference for system operation mode adjustments and low-carbon dispatch decision-making.
