论文摘要
本文提出了一种新型的控制策略，其中在新的动态虚拟发电厂（DVPP）概念中考虑的可再生能源（RES）直接参与次级频率控制（SFC）。这允许这些发电机通过从控制和合同的观点符合相同的规格来充分以与经典同步发电机相同的方式参与SFC。已经提出了一个内部实时重新配置，以在DVPP中说明DVPP，以确定每个RES单元的主动功率注入量，以便在次要级别提供频率支持。整个控制方案旨在考虑现代电力系统的快速动力和缓慢的动力学，这些动力系统既包含经典同步发电机，又包含可重量的能源的快速电源电子设备，其中DVPP应该插入。通过对具有混合风电厂和经典同步发电机的两个面积基准测试的模拟研究，已经验证了次级频率控制策略的性能。这项工作是H2020 Posytyf项目（https://posytyf-h2020.eu/）的一部分。
This paper proposes a novel control strategy in which Renewable Energy Sources (RES) considered in a new Dynamic Virtual Power Plant (DVPP) concept directly participate to Secondary Frequency Control (SFC). This allows full participation of these generators to SFC, i.e., in the same manner as classic synchronous generators by fulfilling identical specifications from both control and contractual points of view. An internal real-time redispatch has been proposed to account in DVPP in order to determine the amount of active power injection by each RES unit for provision of frequency support in secondary level. The whole control scheme is designed to take into account both rapid and slow dynamics of modern power systems which contain both classic synchronous generators and rapid power electronics for renawable energy sources in which DVPP is supposed to be inserted. The performance of secondary frequency control strategy has been validated through simulation studies on a two-area benchmark with mixed wind power plants and classic synchronous generators. This work is part of the H2020 POSYTYF project (https://posytyf-h2020.eu/).
