To address the challenges of low short-circuit ratios and insufficient voltage support in renewable energy bases located in "desert, Gobi, and barren" areas, this paper proposes a coordinated configuration method for reactive power compensation devices that integrates voltage support, inertia contribution, and economic efficiency. First, the transient support characteristics of various compensation devices, including synchronous condensers, grid-forming (GFM) energy storage systems, and static var compensators (SVC), are analyzed. Based on the short-circuit current contribution coefficient, inertia time constant, and life-cycle cost (LCC), a multi-dimensional equivalent support efficiency factor is constructed. This factor is subsequently incorporated into the Generalized Equivalent Dynamic Short-Circuit Ratio (GED-SCR) index as a "virtual short-circuit capacity" weight coefficient, enabling a unified quantitative evaluation of the support capabilities provided by heterogeneous compensation devices. Second, a calculation method for the critical short-circuit ratio considering equipment characteristics is derived based on maximum power transfer limits. A two-stage coordinated configuration strategy is then proposed, aiming to minimize the cost per unit of strength enhancement while ensuring the generalized short-circuit ratios meets the criteria for a "strong system." Finally, simulation results based on the IEEE 33-bus system demonstrate that, compared to conventional configuration schemes, the proposed method reduces the total investment cost and elevates the system short-circuit ratios to above 21.3%, effectively enhancing the voltage support strength of the renewable energy base.
