本文引入多智能体建模方法,构建了政府、用户、燃气公司、实时监控和人机交互五类智能体,通过智能体的协助与交互模拟由于价格变化所引起的城市天然气管网需求与运营的动态变化过程.并且以郑州市为例,对工商业用户实施分时定价政策,模拟了该地区天然气管网的运行状态.结果表明:1)在保证用户和燃气运营商同时获益的情况下,存在一个最优的价格关系能有效降低燃气管网的峰谷负荷差.2)在峰价格逐渐上调的过程中,工商业用户效益是单调递增的,而燃气运营商的效益是先减少后增加的,即价格上调到一定程度后,燃气运营商才开始获益.
In this paper, we introduce a multi-agent modeling approach to build five types of agents: government, users, gas companies, real-time monitoring and human-computer interaction. Through the assistance and interaction of agents, the demand and operation of urban natural gas pipelines , And taking Zhengzhou City as an example, this paper implemented a time-sharing pricing policy for industrial and commercial users to simulate the operation status of natural gas pipelines in the region.The results show that: 1) In the case of guaranteeing both users and gas operators to benefit , There exists an optimal price relationship which can effectively reduce the peak-valley load difference in the gas pipeline network.2) In the process of gradual increase of peak price, the benefit of business users monotonically increases, while the benefit of gas operators is to decrease and then increase , That is, gas prices rise to a certain extent, gas operators began to benefit.
