The simulation results on the IEEE 30-bus system show that the profits of a wind plant are increased when there is a backup power agreement from the thermal power plant or energy storage systems. It also demonstrates that the profitability of a wind power plant can be enhanced up to 132% by implementing a backup power agreement …

Energy storage can smooth out or firm wind- and solar-farm output; that is, it can reduce the variability of power produced at a given moment. The incremental price for firming wind power can be as low as two to three cents per kilowatt-hour. Solar-power firming generally costs as much as ten cents per kilowatt-hour, because solar farms ...

From a macro-energy system perspective, an energy storage is valuable if it contributes to meeting system objectives, including increasing economic value, reliability and sustainability. In most energy systems models, reliability and sustainability are forced by constraints, and if energy demand is exogenous, this leaves cost as the main metric for …
