In the context of new power system construction, the proportion of wind power (WP) and photovoltaic (PV) connected to the grid continues to increase, in order to improve the utilization rate of WP and PV, and reduce the impact of solar power fluctuations on the power system and the occupation of system flexibility resources, so the complementarity

In China, C&I energy storage was not discussed as much as energy storage on the generation side due to its limited profitability, given cheaper electricity and a small peak-to-valley spread. In recent years, as China pursues carbon peak and carbon neutrality, provincial governments have introduced subsidies and other policy frameworks.

Energy storage is not arbitrageable under a fixed tariff and therefore not for sale due to its high cost. In a LEM with energy storage, cost is defined by: (3.13) C i ′ = C i + ∑ j = 1 2 E s t − j, i × E p s t − j, i Where E s t − j, i is the energy flow from storage toj i and

3.1.1 economic benefit of time-sharing price At present, the electricity market generally adopts the charging mode of time-sharing electricity price.
