Abstract

The invention discloses a robust economic dispatch determining method and system for a low carbon power system. The method comprises the steps that the operation data of carbon capture units CCPs areacquired; a robust economic dispatch model is established according to the operation data; the Pareto optimal solution set is determined according to the robust economic dispatch model; a dispatch policy is determined in the Pareto optimal solution set by using a Nash negotiation criterion; the dispatch policy takes into account the power generation cost and the carbon emission amount; and according to the dispatch policy, a golden section method is used to determine robust economic dispatch. The robust economic dispatch determining method and system can take into account the power generationcost and the carbon emission amount, and can improve the stability of the low carbon power system.

Description

technical field [0001] The invention relates to the field of optimal scheduling of power systems, in particular to a method and system for determining robust economic scheduling for low-carbon power systems. Background technique [0002] Economic Dispatch (ED) is one of the most basic and important issues in power system operation. Its main task is to complete the power production task under the premise of meeting the operating constraints at the lowest power generation cost. Due to the fact that large-scale thermal power units with advanced technology and low emissions often have higher on-grid electricity prices, the cleanliness and economy of dispatching are contradictory. In order to balance the cleanliness and economy of power system dispatching, Emision Constrained Economic Dispatch (ECED) and Environmental-Economic Dispatch (EED) are mainly used at present. [0003] ECED adds additional emission constraints to the traditional economic dispatch model, and the emission...
