Four abroad research directions of peak shaving problems involving gas pipeline system are summarized, they include the measures of peak shaving, how to set up the withdrawal schedules of underground gas storage, how to apply the steady model to analyze middle or long-term peak shaving problems, and the simulation of short-term peak shaving problems. Several main peak shaving measures in the production are introduced. Three short-term peak shaving scenarios are proposed based on research achievements at home and abroad and the operators' experience. The optimization of peak shaving scenarios is discussed and a multi-objective optimization guideline for short-term peak shaving scenarios is proposed. The characteristics of some popular gas pipeline simulation software, such as TGNET, SPS, and SIMONE, are introduced. The current difficulties in the short-term peak shaving optimization are reviewed, these difficulties include how to set up a sensible multi-objective optimization guideline, how to deal with the fuzzy factors in the multi-objective optimization guideline and pursue an effective algorithm to solve the multi-objective fuzzy optimization.
