As summarized in Table 1, some studies have analyzed the economic effect (and environmental effect) of collaborated development of PV and EV, or PV and ES, or ES and EV; but, to the best of our knowledge, only a few researchers have investigated the coupled photovoltaic-energy storage-charging station (PV-ES-CS)''s economic effect,
The virtual power plant (VPP) plays an important role in managing distributed energy by integrating renewable energy sources, energy storage systems and dispatchable loads. It can not only provide peak regulation services as good flexible resources, but also participate in the electricity market for additional profit.
Based on the background of one province in Central China power grid absorbing local and outer wind power, this paper studied on the peak shaving characteristics of the wind power into Central China power grid from different provinces and regions. By analyzing the output characteristics and typical 24h load characteristics of wind power, the characteristic index
This article discusses a five-year, hourly economic model of vehicle-to-grid energy storage for peak reduction. Several scenarios are modeled for a participant using a 60 kW-h capacity battery electric vehicle, such as the Tesla Model S or Chevrolet Bolt, in the New York City area using pricing data for the years 2010 through 2014.
