Abstract: In order to promote the deployment of large-scale energy storage power stations in the power grid, the paper analyzes the economics of energy storage power stations from three aspects of business operation mode, investment costs and economic benefits, and establishes the economic benefit model of multiple profit modes of demand-side response, peak-to-valley price difference and auxiliary peak shaving service.

First of all, supercapacitors are really capacitors: Their capacitance is determined by two conductive surfaces facing each other. The larger the surface, the smaller their distance and the higher the dielectric. .
Supercapacitors are double layer capacitors whose underlying principle, the Helmholtz double layers, have been known for over 130 years. They are only a few molecular layers. .
The principles of electrolytic capacitors and supercapacitors were discovered at comparable times – in 1875 by Eugène Adrien Ducretet (electrolytic capacitor) and already in 1853 by. .
However, ion shifts and chemical formations of these ions do play a role in the double layer, which is why supercapacitors are also referred to as electrochemical. .
The temperature resistance of supercapacitors is higher than that of accumulators. Also higher powers are possible at lower. [pdf]
