Integrated energy service provider

as a multi-energy supply entity

can participate in market transactions. To explore new profit sources for integrated energy service provider in the electricity market environment

a multi-agent interactive mechanism considering demand response has been constructed. This mechanism takes into account the uncertainties of photovoltaic output

diverse energy demand power

market electricity price

and demand response resource potential. By employing interval optimization methods

a mixed-integer linear programming model is developed to represent the day-ahead operational optimization problem for integrated energy service provider

yielding strategies for energy procurement

equipment operation

and demand response resource utilization. Case studies are verified that demand response mechanism can effectively reduce purchased cost and increase the operational revenue of integrated energy service provider.
