摘要
极端自然灾害的频发给电-气综合能源系统安全运行造成了严重影响,而在灾害发生前制定合理的规划策略可以有效提升系统的弹性。综合考虑扩展与加固规划,结合鲁棒优化与信息间隙决策理论(information gap decision theory,IGDT)提出了一种面向电-气综合能源系统弹性提升的灾前规划方法。首先,以台风作为典型灾害进行灾害不确定性建模,得到系统时空不确定故障集。其次,建立了三级混合IGDT弹性规划模型,上-中层为双层鲁棒扩展规划,其中上层为正常投资扩展规划模型,中层是在上层的基础上优化最严重灾害下的最小失负荷,下层在上-中层规划的基础上基于IGDT对系统进行加固规划。然后,采用列与约束生成算法对模型进行求解。最后,通过算例验证了模型与该方法的有效性。
The frequent occurrence of extreme natural disasters has a serious impact on the safe operation of the integrated electric-gas energy system.However,the resilience of the system can be effectively improved by formulating reasonable planning strategies before the disasters occur.A pre-disaster planning method for resilience enhancement of the integrated electric-gas energy system is proposed by combining expansion and reinforcement planning with robust optimization and information gap decision theory(IGDT).First,typhoon is taken as a typical disaster,its uncertainty modeling is built,and the spatio-temporal uncertain fault set of the system is obtained.Second,a three-level hybrid IGDT planning model of resilience enhancement is established.The upper and middle layer model is built as robust expension planning.The upper layer is the normal investment expansion planning model,the middle layer optimizes the minimum load loss under the most severe disaster based on the upper layer,and the lower layer carries out the system reinforcement planning based on IGDT with the result of the upper and middle layer model.Then,the column and constraint generation algorithm is applied to solve the model.Finally,a test is given to verify the effectiveness of the model and the method.
