Energy storage refers to storing surplus energy if the generation process of renewable energy is random and fluctuates. When renewable power cannot meet the demands, the stored energy is released to compensate for the inadequate power. 3. Which kind of energy storage is suitable for China?
On this basis, an optimal energy storage configuration model that maximizes total profits was established, and financial evaluation methods were used to analyze the corresponding business models.
From the standpoint of load-storage collaboration of the source grid, this paper aims at zero carbon green energy transformation of big data industrial parks and proposes three types of energy storage application scenarios, which are grid-centric, user-centric, and market-centric.
The power grid side connects the source and load ends to play the role of power transmission and distribution; The energy storage side obtains benefits by providing services such as peak cutting and valley filling, frequency, and amplitude modulation, etc.
Based on the forecast results of the daily generation curve and daily load curve, the particle swarm optimization algorithm was employed to allocate energy storage capacity in terms of local power balance and local power storage and local power balance and residual power storage, separately.
In the three scenarios, with the distinction between the two methods of energy storage capacity configuration, it is clear that the storage capacity of the energy with the surplus power online presents far less than with surplus power offline in local equilibrium.
