Parameters Setting for Primary Frequency Regulation of Wind Power in High-Proportion Clean Energy System

摘要

With proportions of wind power and other clean energies generation increasing rapidly, it's of great significance to incorporate them into primary frequency regulation (PFR) for improving dynamic performance of system frequency. This paper firstly analyzes issues relevant to PFR in high-proportion clean energy (HPCE) system, including status of PFR in actual power grid with HPCE and necessity for wind power to extensively participate in PFR. Then, a system frequency response (SFR) model with multienergy is built, and a process for setting PFR parameters of wind power which include deadband, limiting amplitude and droop coefficient is proposed. Finally, based on a certain operation mode of Yunnan Power Grid, a series of simulation using the proposed process are carried out. By constraints of required maximum of system frequency deviation and Rate of Change of Frequency (RoCoF) under various possible operation conditions, recommended values for deadband, limiting amplitude and droop coefficient are given.
