摘要

天然气系统与电力系统的联合运行是能源系统集成的一个重要方向。研究了气电一体化能源系统的机组组合建模方法，建立了考虑机组启停状态的出力、爬坡、持续时间等运行约束。建立了电力系统和天然气系统的矩阵平衡模型。基于发电转移分配因子，提出了联络线安全约束，提出了基于分段线性化方法的燃气轮机气电耦合模型简化方法。最后，采用6节点电力系统和6节点天然气系统，构建一体化的气电能源系统。以经济成本优化为优化目标，验证了本文提出的机组组合约束能有效优化组合系统中的机组运行调度。

Optimal Dispatch of Integrated Natural Gas and Electricity Systems with Unit Commitment

The joint operation of natural gas system and power system is an important direction of energy system integration. In this paper, the unit combination modeling method of integrated gas-electric energy system is studied, and the operation constraints such as output, climbing and duration considering unit startup and shutdown state are established. The matrix balance model of power system and natural gas system is established. Based on the generation transfer distribution factor, the tie line security constraints are proposed, and the simplified method of gas electric coupling model of gas turbine based on the piecewise linearization method is proposed. Finally, 6-node power system and 6-node natural gas system are used to build an integrated gas electric energy system. Taking the economic cost optimization as the optimization goal, it is verified that the unit combination constraint in this paper can effectively optimize the unit operation dispatching in the combined system.
