Abstract

This paper studies the coordinated operation of grid-connected hybrid system (GCHS) composed of pumped storage and wind under hydraulic short circuit operation (HSCO) mode. Firstly, the GCHS model under HSCO and calculation formula of consumption efficiency are derived to analyze the dynamic characteristics of system frequency and consumption efficiency. Then, control analysis of consumption efficiency is carried out, and its control mechanisms are revealed. Finally, coordinated control of system frequency and consumption efficiency is studied. The results show that consumption efficiency of GCHS under HSCO exceeds the constraint range and lasts for a long time, which is caused by the imbalance between transmission power of power grid and output power of pump-turbine under generation mode. By adjusting the frequency regulation strategies of pumped storage system, the power imbalance can be improved to make the fluctuation of consumption efficiency meet control requirements, but system frequency is deteriorated. System frequency and consumption efficiency are two conflicting control objectives under HSCO. Most of sensitive parameters of consumption efficiency and system frequency are power grid parameters. By adjusting the sensitive parameters, the frequency regulation ability of power grid can be affected to realize coordinated control of system frequency and consumption efficiency.
