Research on Micro-grid Planning Technology under the Background of Carbon Neutrality and New Power System

In the context of carbon neutrality and new power system construction, the large-scale access of renewable energy such as wind and solar brings great challenges to the safe and stable operation of the power system. This paper constructs a multi-agent, multi-objective, and multi-layer micro-grid collaborative planning model that comprehensively considers the transmission of multi-layer optimization problems based on the different objectives of multiple entities such as micro grid operators. This model achieves collaborative planning and optimization between renewable energy equipment, energy storage equipment, and network architecture at different time scales, and provides important technical solutions for improving the economic benefits of various entities and promoting the clean transformation of energy and power systems. Finally, this paper designs a simulation case based on the IEEE-33 node system to verify the effectiveness of the model. The results show that the coordinated configuration of renewable energy equipment and energy storage equipment in the micro-grid can significantly improve the absorptive capacity of renewable energy sources on the basis of ensuring the economic benefits of various entities, and thus provide important support for the construction of carbon neutrality and new power systems.
