当今电力系统中，基于换流器的资源渗透率不断提高，需要替代同步发电机对动态电压稳定性和惯性响应的贡献。然而，成熟的电力系统规划方法是串行的，稳定措施仅在规划过程的后期才被考虑。我们研究电力系统规划的集成方法的优势，该方法通过对惯性和电压稳定性的简化稳定性约束，在发电、输电和储能系统扩容的同时考虑稳定措施。我们发现，集成方法可降低系统成本，且网格式电池储能系统的两用选项比静止同步补偿器等其他稳定措施更受青睐。
英文摘要
Increasing penetration of inverter-based resources in today's power systems requires substitution of the contribution from synchronous generators to dynamic voltage stability and inertial response. However, established approaches for power system planning are sequential, as stabilising measures are only considered at a later stage of the planning process. We investigate the advantages of an integrated approach for power system planning, where stabilising measures are considered simultaneously with the expansion of generation, transmission, and storage systems via simplified stability constraints on inertia and voltage stability. We find that system costs are reduced with the integrated approach and that the dual-use option of grid-forming battery energy storage systems is favoured over other stabilising measures like static synchronous compensators.
