Energy storage (ES) represents the temporal shift of electric energy that is fundamentally different from energy generation and consumption and requires new models and market rules for integration in power systems scheduling and pricing practices.
Our research develops fundamental models for scheduling and pricing of flexibility services provided by ES technologies in power systems. Our models show, analytically, how the operation of ES devices creates an intertemporal dependence in marginal electricity prices, where the marginal price during ES discharging has a direct relationship with the marginal price of the times when the ES is charged. In addition, we develop detailed physical models for the integration of ES technologies, such as compressed air energy storage, in electricity markets.
