摘　　要：针对大容量岸电系统并网给电网运行带来的负荷波动大、电能质量差等一系列问题,提出了一种经济高效的补偿方案,旨在提高电网运行的稳定性和安全性。通过研究大容量岸电接入后电网的稳定性,包括岸电功率的波动性,对电网无功功率分布的影响以及系统电压、网损、潮流分布的影响等,建立了大容量岸电的出力模型,对船舶负荷接入的配电网运行状态进行了仿真。仿真结果表明,该方案可提高岸电接入系统的安全稳定性和电能质量,为促进岸电的快速发展和绿色港口的建设提供参考。There are a series of problems such as large load fluctuations and poor power quality caused by the grid connection of large-capacity shore power systems to the grid operation. A cost-effective compensation scheme is proposed to improve the stability and safety of grid operation. The stability of the power grid after large-capacity shore power access, including the volatility of shore power, the impact on the reactive power distribution of the power grid, and the influence of system voltage, network loss and power flow distribution, is studied. On this basis, the output of a large-capacity shore power model is established and the operational status of the distribution network with ship load access is simulated. The simulation results show that the scheme can improve the security and power quality of the shore power access system, and provide a reference for promoting the rapid development of shore power and the construction of green ports.
