Summary:
The large-scale integration of new energy into the power grid has led to significant fluctuations in grid impedance, presenting the characteristics of a weak grid. Traditional grid-following control strategies are difficult to adapt to weak grid scenarios. The grid-forming control strategies based on virtual synchronous machines and droop control have received increasing attention. Research on new topologies of power electronic converters, improved grid-following control strategies, improved grid-forming control strategies, hybrid synchronous control strategies, and new PWM modulation strategies are of great significance for enhancing the operational stability and reliability of large-scale new energy grid-connected power generation systems in the context of the new power system.
大规模新能源接入电网，使电网阻抗大幅波动、呈现出弱电网的特性。传统跟网型控制策略难以适应弱电网场景，基于虚拟同步机与下垂控制的构网型控制策略受到越来越多关注。开展电力电子变换器新型拓扑研究、改进的跟网型控制策略研究、改进的构网型控制策略研究、混合同步控制策略研究、新型PWM调制策略研究等对提升新型电力系统背景下大规模新能源并网发电系统的运行稳定性和可靠性具有重要意义。
