摘要:
针对港口岸电系统负荷侧存在的冲击性功率等电能质量问题,提出一种储能型电能调控装置容量优化配置方法。介绍港口岸电系统及储能型电能调控装置拓扑结构,并分析冲击性负荷运行特征;探讨负荷运行工况与功率因数控制目标之间的关系,根据电池荷电状态与负荷运行工况,提出储能型电能调控装置多类型运行工况自适应容量设计的补偿控制策略;建立储能型电能调控装置技术-经济模型,通过在技术模型中考虑岸电系统电能质量的要求建立容量模型,经济模型提供评估寿命成本和效益的方法。基于某港口岸电负荷实测数据,验证所提方法的有效性。

Abstract:
Aiming at the power quality problems such as impact power on the load side of port shore power system, a capacity optimization method of electric power regulator with energy storage is proposed. The topological structures of port shore power system and electric energy regulator with energy storage are introduced, and the operation characteristic of impact load is discussed. The relationship between load operation condition and power factor control objective is analyzed. According to the state of charge of battery and load operation condition, a compensation control strategy for adaptive capacity design of electric power regulator with energy storage under multiple operation conditions is proposed. A technical-economic model of electric energy regulator with energy storage is established, a capacity model is built by considering the power quality requirements of shore power system in the technical model, and the economic model provides a method to evaluate the life cost and benefit. Based on the measured data of port shore load, the effectiveness of the proposed method is verified.
Key words:  shore power system  impact power  power quality  electric energy regulator with energy storage  capacity optimization
