基于全景量测的聚合电网概念、调控方法及其应用

随着可再生能源发电大规模并入电网发输配用各个部分，为使源网荷在频率限定范围内最大限度地消纳可再生能源有功发电，需对其运行调控实施全局统筹。为此，在电网全景过程化量测条件下给出聚合电网调控方法。提出聚合电网、可观测点、可观测点的观测函数和调控函数的概念，在此基础上，给出聚合电网性能指标，提出可观测点、可观测点的观测函数和调控函数之间的互动关系，实现聚合电网渐进调控机制。在线调控算例对所提方法进行了验证。

Concept, dispatch and control method, and application of aggregation grid based on panorama measurement

With the renewable energy generation merging into each part of generation, transmission, distribution and use of power system, in order to maximize the absorption of renewable energy active power generation within the frequency limit, it is necessary to implement overall planning of their operation, dispatch and control. Therefore, a dispatch and control method for aggregation grid is given under the environment of panorama procedural measurement of power system. The concepts of aggregation grid, observable point, observable function and dispatch and control function of observable point are given, on this basis, the performance indexes of aggregation grid are given. The interaction among observable point, observable function and dispatch and control function of observable point are proposed to realize the gradual dispatch and control mechanism of aggregation grid. The case of online dispatch and control verifies the proposed method.
