摘要

微网是一种能够灵活容纳可再生能源发电的小型电力系统，一般具有高比例的可再生能源渗透率和利用率，具备孤岛运行能力。随着含高比例可再生能源发电的微网的容量逐渐增大，其作为黑启动电源为大停电后电力系统中待恢复机组提供启动功率的潜力得到越来越普遍的认可。在此背景下，对微网作为黑启动电源时的电力网架重构优化问题开展研究。首先，分析了含高比例可再生能源微网作为黑启动电源的优势及其可行性。然后，以最大化恢复系统的发电量和最小化微网内的负荷损失量为目标构建计及微网作为黑启动电源的网架重构优化模型，并基于节点重要度和路径恢复时间构建综合路径评价指标以优化待恢复机组的恢复路径。最后，以新英格兰10机39节点系统为例说明了所提方法的可行性与有效性。

Abstract

A microgrid is a small-scale power system that can flexibly accommodate high penetration and utilization of renewable energy generation

and operate with a high efficiency as well as act as a stand-alone island. With the ever-increasing capacity of a microgrid with high penetration of renewable energy generation

the feasibility of the microgrid acting as a black-start power source has been more and more widely recognized. The optimization problem of power network reconfiguration is studied

in which the microgrid acts as a black-start power source. The advantages and feasibility of the microgrid with high penetration of renewable energy generation acting as black-start power source are first presented. Then

maximization of the energy capability of the restoration system and the minimization of the load losses of the inner microgrid are formulated as the objectives of the reconfiguration model. The restoration paths of the units to be restored are optimized with respect to a path evaluation index that integrates the node importance and the recovery time of restoration paths. Finally

the New England 10-generator 39-bus power system is employed to illustrate the feasibility and validity of the proposed method.
