Operation of energy hubs with storage systems, solar, wind and biomass units connected to demand response aggregators

•Day-ahead scheduling has been carried out for energy hub.•Uncertainties of demands, PV, solar heat, wind and electricity prices are considered.•Demand response aggregator has been used as an input source of electricity.•Demand response effect on EH operation cost has been investigated.•Effect of storage systems on hub operation costs have been evaluated.
