Park power distribution network power supply capability analysis method

The invention relates to a power supply capability analysis method for a park power distribution network, and the method comprises the steps: building a safety domain model of the park power distribution network, searching for the load increase criticality and a load upper limit boundary, and searching for the load reduction criticality and a load lower limit boundary, building a power supply capability upper and lower limit curve model of the park power distribution network, and carrying out the calculation of the consumption capability of the park power distribution network. The method achieves the evaluation of the park power distribution network, guides the subsequent planning and construction of the park power distribution network, and serves the development of the park. 本发明涉及一种园区配电网供电能力分析方法，通过构建园区配电网安全域模型，寻解负荷增长临界性与负荷上限边界、负荷消减临界性与负荷下限边界，建立园区配电网供电能力上下限曲线模型，开展园区配电网的消纳能力的计算。本发明实现对园区配电网进行评估，指导园区配电网后续规划建设，服务园区发展。
