Research and application of a gas pipeline peak shaving project evaluation system (GPPES)

Inspired by the large system cybernetics and multi-objective decision thoughts, we combined the natural gas pipeline transport theory, comprehensive evaluation theory and decision-support system to develop a gas pipeline network peak-shaving project evaluation system (GPPES). This system includes an evaluation database with a management system, an evaluation methodology library with a management system, an evaluation model library with a management system, and a Human-Machine Interference system, with the following functions: data management, loading of technological parameters of Stoner Pipeline Simulator (SPS), process calculation of gas storage and peak load regulation capacity, image display of working conditions, output of intermediate and final evaluation results, and browse of evaluation system help. Many project cases demonstrated that GPPES helps make a better environment for operators to make decisions on gas transporting and dispatching management,achieve the promptness and scientificity of peaking load and dispatching decision making, update the management ideas and modes, optimize the associated operation schemes, save the operation and management cost, shorten the decision-making period, and enhance the whole operation quality of natural gas pipeline networks.
