Planning for Improving the Flexibility of Regional Comprehensive Energy System Considering Uncertainty

The internal energy coupling and the external environment influence make the operation scene of regional integrated energy system more and more complex and the uncertainty problem more and more prominent. In addition to the usual uncertainty of energy side and load side, the uncertainty of coupling equipment conversion efficiency is considered, and the uncertainty interval of output power is given. Based on this, puts forward the planning and evaluation model of regional integrated energy system flexibility in ascension, first to economy optimal flexibility as a target for promotion planning, safety assessment, the resulting satisfy both good economical efficiency and safety of planning as a result, and is verified by an example and analyze the effectiveness of the model.
