Optimal Operation of an Integrated Electricity-heat Energy System Considering Flexible Resources Dispatch for Renewable Integration

Large fluctuations may occur on the energy supply and load sides when large-scale renewable energies are integrated, leading to great challenges in power systems. The curtailment is especially numerous integrated electricity-heat system (IEHES) account of coupling. flexible resources (FRs) both introduced into optimal dispatch IEHES further modeled alleviate this paper. On side, three kinds FRs based coordination discussed. shiftable electricity demand resource characterized. basis, solution for participating given, with goals maximizing penetration ratio lowering operation costs. Two scenarios performed, results indicate that proposed strategy can effectively reduce improve flexibility IEHES. contribution degrees different integration also explored.
