| description | To solve the problem of safe and stable grid operation caused by the uncontrollability of renewable energy power generation with a high proportion, this paper focuses on the method of energy storage participation in grid supply and demand balance regulation based on differentiated electricity prices. From the perspective of demand-side and regulable resources, the paper investigates the method of using differentiated electricity prices to improve demand-side responsiveness and expand energy storage operation revenue, so as to explore and activate the potential of regulable resources in the grid. Firstly, the necessity and feasibility of considering differentiated electricity prices are analyzed. Secondly, a demand-side response and energy storage regulation model based on differentiated electricity prices is established, and the supply–demand balance regulation method considering differentiated electricity prices is proposed. Then, the supply–demand balance regulation process under two conditions before and after the implementation of differentiated electricity prices is compared and analyzed through case simulation. Finally, via the practical example, the effectiveness of the method is verified, and the proposed method is able to reduce the demand for energy storage by half in rated power and reduce the rated capacity of the energy storage to 8.66%. |
