基于资源优选分级的配电网阻塞管理措施优化组合
摘要：由于电网用电负荷量的持续增长以及分布式电源渗透率的升高，配电网会出现潮流过载并导致阻塞，针对配电网阻塞问题，提出了一种基于多种资源优选分级的配电网阻塞管理措施优化组合方法。首先，将能缓解配电网阻塞现象的资源定义为阻塞管理资源，并对配电网中中源、网、荷、储侧的共6种阻塞管理资源建立相应的数学模型；其次，定义了衡量资源阻塞管理水平的指标，并通过灰色定权聚类对阻塞管理资源进行了优选分级；然后，在考虑了动态增容设备全寿命周期成本的基础上，以阻塞管理总成本最小为目标建立了配电网阻塞管理措施优化组合模型，并通过和声搜索算法进行了求解；最后，通过一个具体的配电网算例，验证了所提出的阻塞管理方案能够减少阻塞管理措施的动作量，并且具有更好的经济性。
Abstract:Due to the continuous growth of the power load and the higher penetration rate of distributed generation, the power flow overload of the distribution network will appear and cause congestion.An optimization combination method of distribution network congestion management measures based on the optimization and classification of various congestion management resources was proposed to solve the problem of distribution network congestion. Firstly, the resources that can alleviate congestion in the distribution network were defined as congestion management resources; and corresponding mathematical models were established for six types of congestion management resources on the source, network, load, and storage sides of the distribution network. Secondly, the index to measure the level of resource congestion management was defined, and the optimal classification of congestion management resources was carried out by a grey fixed-weight cluster. Thirdly, on the basis of considering the life cycle cost of dynamic capacity enhancing equipment, the optimal combination model of distribution network congestion management measures was established with the objective of minimizing the total cost of congestion management; and was solved by the harmonic search algorithm. Finally, through a specific distribution network example, it is verified that the proposed congestion management scheme can reduce the action amount of congestion management measures and has better economic efficiency.
