The invention discloses an RISC-V processor verification method and system and a storage medium. The method comprises the following steps: monitoring version change of a register transfer level hardware circuit code of the RISC-V processor to establish a change influence domain; and constructing an inter-module relationship graph according to the change influence domain, and positioning a verification scene based on the inter-module relationship graph. And generating a test case in the verification scene, and performing RISC-V processor verification according to the test case. The modification points in iterative development are determined based on the version evolution trajectory, and the change influence domain is established according to the modification points, so that a basis is provided for limiting a verification scene; and a clear boundary is provided for the generation of the test case through the establishment of the verification scene, so that the problem of fuzzy verification range in the development iteration of the processor is effectively solved, the consumption of test resources is greatly reduced, the full-chip simulation is avoided, the feedback period is shortened, the verification efficiency is improved, and a reliable guarantee is provided for the rapid iterative optimization of the processor.

This invention discloses an active support configuration method and equipment for urban power hollowing-out areas, comprising: based on typical urban power hollowing-out scenarios, comprehensively screening the requirements of typical scenarios, combining the characteristics of the equipment's VSC converter, and proposing an active support integrated solution through VSC control strategy improvement and reactive power system coordinated control. Based on the N-1 and N-2 stability results of a single fault scan, the installation site is calculated and the optimal site is selected for installation through local topology network characteristics, featuring simplicity, speed, efficiency, and economy. This method is applicable to urban power hollowing-out scenarios in the construction of new power systems in China, urban power grids with low short-circuit ratios, coastal urban power grids with large-scale renewable energy access, and receiving-end urban power grids with dense DC access, thus having a wide range of applications. The optimal site selection based on the grid topology, combined with functional integration using VSC characteristics, is more intensive and economical than conventional solutions.
