The spatial diffusion of “multi‐station integration” and sustainable development: From the perspective of eight economic zones in China

Abstract

China's power system driven by the ubiquitous power internet of things, a new operation mode—“multi-station integration” (MSI) has emerged. The novel business model can improve the energy utilization efficiency and promote the cross-border business integration. In some earlier studies, mainly focused on conceptual analysis of application scenarios and operation modes of MSI. However, quantitative analysis that measure MSI popularize remain under development. This article highlights the recent advance achievements in MSI of digital power grid regarding transformation of Chinese eight economic zones. From the perspective of spatial heterogeneity, the gravity model provides a framework for describing the spatial diffusion of MSI mode relative to eight economic zones (EEZ) in China. In addition, compared to conventional gravity model, this study improved four aspects of the basic spatial gravity model - diffusion capacity, absorptive capacity, the gravitation coefficient, and economic distance. It is found that the spatial diffusion of MSI is subjected to eight economic zones interaction while the spatial heterogeneity is inevitable. Thus, the resulting represents a radial decline, with the three coastal economic zones as the center, gradually decreasing to the inland and western regions, especially for those coastal economic regions with large diffusion impacts. Meanwhile, we also discuss the advantages, impacts, and limitations of MSI spatial diffusion as valuable references for future development direction of MSI mode. Ultimately, some of future development recommendations for MSI emerging field is put forward.
