Conditional Distributionally Robust Optimization of Integrated Electricity and Heat Systems With Variable Flow Regulation Modes
摘要
Abstract
The integrated electricity and heat system(IEHS)can effectively promote renewable energy accommodation.The refined model of the district heating system and the reasonable model of the renewable energy uncertainty model are challenging aspects of the IEHS dispatch problem.This paper first establishes a conditional distributionally robust optimization model of IEHSs with variable flow regulation modes,which has two main improvements over the existing studies.First,this paper establishes a conditional distributionally robust optimization by adopting the trim ambiguity set to model the the intrinsic dependence between the renewable energy forecast error and its forecasted output information,which can guarantee the security and optimization of dispatch results.Next,an IEHS model with variable flow regulation modes based on the energy conservation equation and the one-order implicit upwind method is established to fully exploit the flexibility of the district heating system and promote renewable energy accommodation.The proposed model has random variables and bilinear constraints,which is difficult to solve directly.Thus,this paper transforms with random variables into a nonlinear deterministic model through the duality theory and conditional value at risk approximation approach.Then,this paper proposes an adaptive McCormick algorithm to solve the model with nonlinear constraints.Case studies with different scale IEHSs show that the model established in this paper can effectively reduce the dispatch cost of IEHS,and the adaptive McCormick algorithm can obtain an approximate optimal solution while guaranteeing feasibility,with an optimal gap of less than one thousandth.关键词
