The Optimal dispatch for Urban Gas Supply Systems
城市煤气供应系统优化调度

In this paper, algorithms of two levels for optimal dispatch for urban gas supply systems are proposed. First, based on the principle of decomposition-coordination, an algorithm for solving the optimal dispatch problem of mid-pressure distribution system is proposed; second, the analytic solutions of optimal dispatch for lowpressure distribution system are derived and their corresponding algorithm is proposed. The computational examples show that the results obtained are satisfactory.
