中文摘要:

针对岸电系统供电模式由单一电网侧供电变成由风、光、网、储等多源供电，所带来的新能源出力波动，消纳率降低等问题。通过构建基于移动储能装置的多源融合岸电协调运行模型，将岸电子系统通过公共母线互联实现闭环运行。提出了岸电分层分布式运行优化策略，通过边缘计算技术实现对各分布式子系统的实时就地协调，减小因预测误差，出力波动性带来的弃风弃光问题。基于电网的分时电价机制，通过移动储能的“谷充峰放”和“转移消纳”的工作模式实现岸电能源的优化调配技术，达到平抑分布式能源出力波动，提高岸电系统的经济性与可再生能源消纳率的效果。同时也为建立港口岸电系统互联运营的优化平台打下良好的基础。

英文摘要:

For the shore power system, the power supply mode has changed from a single grid side power supply to a multi-source power supply such as wind, light, grid, and storage, which brings about the fluctuation of new energy output and the reduction of For the shore power system, the power supply mode has changed from a single grid side power supply to a multi-source power supply, such as wind, light, grid and storage, which brings about the fluctuation of new energy output and the reduction of consumption rate. In this paper, by constructing a multi-source integrated shore power coordinated operation model based on mobile energy storage devices, the shore electronic system is interconnected through a public bus to achieve closed-loop operation. A stratified and distributed operation optimization strategy for shore power is proposed. Firstly, edge computing technology is used to realize real-time on-site coordination of various distributed subsystems to reduce the problems of wind abandonment and light abandonment caused by forecast errors and output fluctuations. Secondly, based on the time-of-use electricity price mechanism of the power grid, through the "valley charge and peak discharge" and "transfer and absorption" working modes of mobile energy storage, the optimization of shore power energy allocation technology is realized, so as to stabilize the fluctuation of distributed energy output and improve the economy of the shore power system and the consumption rate of renewable energy. Meanwhile, it also lays a solid foundation for the establishment of an optimized platform for the interconnection and operation of port shore power systems.
