摘要
“双碳”目标下,以风电、光伏、光热发电为主的源端新能源规模化并网以及荷端供给需求和种类的多样性使得系统源荷平衡受到极大影响,给新型电力系统运行带来严峻挑战。基于此,以风电-光伏-光热-火电联合发电系统为研究对象,提出一种考虑源荷双重不确定性的鲁棒模糊动态综合环境经济调度模型。首先,分别基于鲁棒理论和模糊理论对多源系统源荷不确定因素建模,同时构建鲁棒模糊数学模型并推导其等价确定模型;其次,综合考虑各种环境经济因素,构建多源系统鲁棒模糊动态综合环境经济调度模型;然后,根据其等价确定转化思想对模型进行转化并采用基于差分进化的粒子群算法求解;最后,基于新疆哈密电网实际数据和改进IEEE-39节点系统,验证所建模型的寻优效果在环境经济上的可行性、有效性及优越性。
The large-scale grid connection among wind power,photovoltaic and concentrating solar power as well as supply demand and diversity of load types will greatly influence source-load balance under condition of carbon peak and carbon neutrality,which brings severe challenges to the operation of the new power systems.Therefore,a robust fuzzy dynamic comprehensive environmental economic dispatch model considering the twofold uncertainty of source-load was proposed after the wind power-photovoltaic-concentrating solar power combined power generation system was taken as a research object.Firstly,the uncertainty of source-load was modeled based on robust theory and fuzzy theory,respectively.Meanwhile,a robust fuzzy mathematical model was constructed and the equivalent determination model derivation was performed.Secondly,a robust fuzzy dynamic comprehensive environmental economic dispatch model was constructed considering various environmental and economic factors.Besides,the model was transformed and solved according to its equivalence transformation idea and particle swarm optimization based on differential evolution.Finally,based on the improved IEEE-39 bus system and actual power grid in Xinjiang Hami,the optimization effect of the model were verified in the aspects of feasibility,effectiveness and superiority of environmental economy.
