Compared with the territorial management model, the trading model reduces the cost by 4.52% and increases renewable energy power by 414.29 × 10 8 kWh. When the TGC futures price fluctuates by 30% around CNY 68.2, the RPS target realization cost changes slightly, which proves that the inter-provincial TGC futures trading model is robust.
A multi-microgrid distributed energy trading model based on blockchain technology and Gale-Shapley algorithm and a bilateral matching mechanism based on the Gale-Shapley algorithm is proposed, which ensures stable matching results for buyers and sellers in the two-way selection of the trading market. The distributed trading of power among multi …
To address this ongoing conflict, provinces with inadequate local energy provisions have turned to domestic and foreign energy resources, typically through direct energy trade [4,5]. By transferring energy resources domestically from west to east, China''s interprovincial inequality in energy availability has been largely alleviated [6].
By 2031, the installed capacity of large-scale battery storage in Europe is expected to increase twentyfold. This is good news for the energy transition and for the stability of the power grid. But it also means that operators of storage systems will increasingly be in competition not only with other flexibility options, but also with each other.
The calculation example analysis shows that compared with the traditional model, the "three-stage" model can bring better benefits to the pumped storage power station, and when the actual value of demand fluctuates within −8%, the pumped storage power station has the ability to resist risks higher than the market average.
