The invention discloses a regional
integrated energy system operation
robust optimization method considering
electricity-to-gas conversion and uncertainty, and the method comprises the steps: carryingout the detailed modeling of an
electricity-to-gas conversion process according to the principle of an electrochemical reaction, and analyzing the
coupling relation between different energy forms ina matrix mode based on an energy center model; establishing a regional comprehensive
energy system operation optimization model considering the uncertainty of various load prediction powers, and establishing a two-stage
robust optimization model according to a polyhedral uncertain interval; and decomposing the two-stage
robust optimization model into a main problem and a sub-problem, converting the sub-problem into an
optimization problem of a single target, and carrying out iterative solution to obtain a comprehensive
energy system robust optimization scheme. According to the method, the potential of complementary mutual relief and
flexible scheduling among multiple energy forms is fully excavated, wind curtailment can be reduced, and the operation economy and flexibility of the comprehensive
energy system are improved; and the contradiction between the operation risk and the cost can be coordinated according to the actual condition of the regional
integrated energy system.
