Dynamic response price of energy storage power station
Therefore, in the context of the existence of SPS, this paper focuses on studying how to effectively schedule flexible resources and how to formulate dynamic electricity prices to incentivize tenants' participation in DR. The electricity price for tenants in the commercial building is generally issued by a subcontracting power supplier (SPS), and the tenants cannot directly interact with the energy retailer. A Stackelberg game is used to model interactions between a retailer and its customers; the retailer sets the day-ahead hourly price of electricity and consumers adjust real-time consumptions to maximize. The integration of renewable energy sources and the drive towards decarbonisation have accelerated the adoption of demand response and dynamic pricing mechanisms in electricity markets. This paper clarifies objectives, constraints and optimization techniques.
