提出了一种求解城市电网最大供电能力指标的模型，该模型是一种基于直流潮流的线性规划模型，以网络所能供应的最大负荷为目标函数，以网络的功率平衡、各支路(线路、变压器)的额定容量、电源点和负荷点的功率约束为基本约束条件。以我国某地区城市的实际网络为算例来验证该模型的有效性，并采用传统潮流计算方法验证了该模型的准确性。

ABSTRACT: A model to solve maximum power supply capability of urban distribution network is proposed, which is based on linear programming model of DC power flow. In the
proposed model the maximum load power is taken as objective
function, and the power balance of network, rated capacity of
all branches (including lines and transformers), power
constraints at power source points and load points are basic
constraint conditions. Taking the actual distribution network of
a city in a certain domestic district for example, the
effectiveness the proposed model are verified, and the accuracy
of the proposed model is also verified by traditional power
flow calculation method.
KEY WORDS: urban distribution network；DC power flow ； linear programming ； maximum power supply capability
