Today''s and future energy storage often merge properties of both batteries and supercapacitors by combining either electrochemical materials with faradaic (battery-like) and capacitive (capacitor-like) charge storage mechanism in one electrode or in an asymmetric system where one electrode has faradaic, and the other electrode has capacitive

Economic value and government compensation calculative method of energy storage system Abstract:Energy storage system (ESS) has recently been highlighted because of their many benefits such as high operation reliability, fast and accurate response ability, environmentally friendly, and so on.
The key issue in capacity tariff design is maximising the system benefit by guiding the behavior participants through the benefit allocation mechanism. At the renewable energy configuration level, some researchers have explored effective capacity optimisation strategies [27, 28 ].
Capacity tariff mechanism of PHS can reduce the benefit allocation unfairness. stations (PHSs) to provide capacity support can effectively improve renewable energy utilisation in (IRESs). Historically, the contribution evaluation of the PHS near the load side has been the focus, whereas the PHS near the power side has not yet been evaluated.
After paying the compensation costs, the residual income was allocated to each enterprise based on the principle of efficiency. Finally, the capacity tariff was calculated by deducting the electricity revenue from the compensation and allocation benefits obtained by the PHS. 2.1. Total revenue of the integrated renewable energy system
From the perspective of fair distribution, a capacity tariff pricing mechanism based on the capacity allocation method is more suitable. First, the capacity of the PHS corresponding to the maximum IRR of each enterprise is the same (1200 MW).
This phenomenon shows that with an increase in the PHS's capacity, its marginal contribution value increases, resulting in an increase in the IRR and capacity tariffs. Subsequently, the capacity of the PHS continues to increase, and its investment cost significantly increases.
