An improved affine arithmetic‐based optimization method for district energy systems with uncertainties

In the process of district energy system (DES) operation and dispatching, there are various uncertainties brought by strong coupling equipment fluctuation internal external surroundings, these uncertain parameters often correlated. this paper, an improved affine arithmetic-based method is proposed to solve economic dispatching problem DES with correlated uncertainties. First, optimal model considering environmental factors constructed. An algorithm introduced interval arithmetic used improve extension high-order noise element. Taking a classical as example, analyzed using deterministic method, method. The application effect under different scale amplitude also discussed. results show that can effectively reduce width target value compared traditional optimization which further contribute decision.
