摘要(Abstract):
随着我国分布式可再生能源快速增长,高效消纳的问题日益突出,基于电力电子变压器(power electronic transformer,PET),构建可实现大范围互联互济的交直流混合系统成为新的发展趋势。文章在分析国内外研究现状及存在问题的基础上,提出一种"场景生成-互补优化-协调控制"时序递进的优化运行控制体系,包括交直流混合系统运行场景生成方法、计及电力电子变压器调控能力的多时间尺度可再生能源互补优化策略、交直流混合系统协调控制技术等3个方面,进一步给出了交直流混合的分布式可再生能源互补优化运行控制方面亟待研究的关键技术和研究方案。最后,给出了示范验证项目的应用场景。
