“…A spatial econometric model is applied to precisely estimate the role of technical assistance for energy poverty in sub-Saharan African countries, compensating for the shortcomings of traditional econometric models [35]. To study the correlation and the effect weight among multiple variables, [36] adopted the economic model based on fuzzy decision-making; the dynamic conditional correlation mixed-data sampling model is applied in [37,38], presents mathematic regression to analyze the influence of the environmental innovations on economics, and the Granger causality test approach and the impulse response function analysis are given in [39]. In the field of smart apartment buildings, compared to several energy resources, a Pareto front is generated through multiobjective optimization with cases using k-means to simplify annual data, reducing the total cost and carbon dioxide emissions [40,41].…”

Megawatt-impulse power generated by Tokamak fusion devices seriously threats to the stable operation of the whole system. The current power supply scheme needs to leave large redundancy to suffer such a huge power impact, resulting in a high cost of the power supply system. Moreover, no reasonable configuration for impulse power and stable power causes unnecessary waste of power supply capacity. The rapid development of energy storage technology provides a potential approach to solve the operation stability problem caused by large amounts of power impact. Thus, a novel hybrid power supply scheme is creatively put forward with centralized energy storage, which can effectively decrease the voltage level of the grid and achieve smooth connection into the public grid when validly compensating for the impulse power. The cost evaluation model and principles are proposed to analyze and assess the economic advantages of the hybrid power supply scheme with centralized energy storage. Finally, a power scenario based on the international thermosnuclear experimental reactor (ITER) is applied as a case study of the cost evaluation model for various schemes, and the results verify that the novel hybrid power supply scheme has benefits on economics and the capacity of the grid over other schemes.
