“…The actual generation of renewable energy units, that is, wind farms and solar stations, is limited by their forecasting result, as shown in (13)(14)(15)(16). In ( 13) and ( 14), the actual generation of wind power and solar power is limited by their predicted output.…”

“…To cope with the fluctuations from RESs and forecasting errors, a multi‐service optimal planning approach for ESSs was presented in [12], where the power reserves and energy autonomy of ESSs were explicitly modelled with an hourly resolution. In [13], the location and capacity of ESSs in an ultra‐high voltage (UHV) transmission network were optimized to enhance the power delivery capacity, thus promoting renewable energy accommodation. Nevertheless, the studies mentioned above primarily focus on RES planning methods or ESS planning approaches in power systems with existing RES installed capacity, while ignoring the coordinated planning of RESs and ESSs.…”

The continuous growth of renewable energy sources (RESs) has increased the demand for flexibility in managing uncertainties of RES generation. Energy storage systems (ESSs) are recognized as one of the promising methods to address this challenge. For multi‐area power system planning problems, capacity allocations of RESs can vary considerably among areas accounting for the geographic diversities in RES generation and load patterns. This paper presents a hierarchical coordinated planning model considering the interaction of local‐area (LA) planning entities and the system‐wide (SW) planner. A novel multi‐objective LA planning model is proposed to compute optimal capacity configuration ratios of RESs and ESSs based on regional resource characteristics. The SW planner acts as a coordinator and further optimizes specific capacities of generation assets. Optimal configuration ratios produced by LA planning entities are important indices reflecting LA planning preferences and serve as a link between the two planning layers. Numerical results on a modified NREL‐118 test system show that the proposed planning model can reduce carbon emission by an average of 10.5% and improve the RES utilization rate by an average of 1.8% compared with planning models without considering configuration ratios and ESS installations.

“…For the eastern region, as the price of electricity that is sent from the west is lower than the feed-in tariff of local power plants that are built in the eastern provinces, the reduced costs for energy consumption in the east and central regions helps to maintain the price advantage of local products in both the domestic market and international competition, and promotes the development of advantageous industries [14][15][16][17]. Moreover, the development of UHV and a smart grid will also promote the development of electric vehicles, which gives full play to the environmental benefits of clean energy and solves the effect of urban environmental pollution [18]. As a landmark technology achievement of China's energy revolution, and a major breakthrough in the development of advanced productivity, the UHV transmission project has become a "national weapon" to promote the energy production and consumption revolution and to coordinate the sustainable development of energy and the economy [19,20].…”

As one of the largest energy consumers in the world, China’s total electricity consumption has increased by 416.33% during the sample years of 2001 to 2019. In 2019, the top five provinces in terms of power use were all located on the eastern coast. They have contributed 38.39% of the total consumption, causing a power shortage of 594.5 billion kWh in the provinces, while the power generation in the central and western regions have far exceeded their electricity consumption. In order to alleviate the problem of the mismatch between the power resource centers and the load centers in China, ultra-high voltage (UHV) projects, as one of the most important projects in recent years, have bridged the resource gap between the regions and have improved the allocation efficiency of the power resources. Although the cross-provincial transmission of electricity opens the pathway for the consumption of resources, the causal effects of the project on the regions along the line have not been accurately analyzed. Firstly, by constructing a quasi-natural experiment, this paper uses county-level panel data during the period of 2000 to 2019 to analyze the economic benefits that are generated by the inter-regional power transmission project. Secondly, the pathways of the economic effects of UHV are also verified. Finally, this paper also analyzes the heterogeneous effect of power-resource-rich provinces in the construction of the project. Through the pathways of local enterprise dynamics, employment level, and industrial structure, the findings prove that cross-regional power transmission has significantly enhanced the economic growth of the related regions and has played an especially positive role for the power exporting provinces. This paper provides empirical evidence for the effect of optimal resource allocation and the infrastructure development of developing countries and supplies a policy reference for developing countries’ resource allocation optimization strategies.
