Abstract

This paper studies a single-phase bidirectional grid tied inverter connected to a common DC-bus, together with a photovoltaic installation and a battery energy storage system. The design of this system and its control mechanisms are discussed. Appropriate components are determined and the system is implemented in the SIMULINK environment. The DC-link voltage is controlled by the battery which leaves the reference current provided to the inverter undetermined. This free parameter leaves room for optimization purposes. In this work an optimization for the electricity price is studied as nowadays variable price contracts and even spot price tied contracts are available on the energy market. Consumers could benefit of these types of contract when making use of a battery energy storage system. The results of this optimization and a full economic analysis of the system conclude this work. The full analysis furthermore discusses an optimal sized battery and inverter for given input parameters of the system. Finally a sensitivity analysis is carried out to study the effects of these parameters.

电池储能并网住宅光伏系统的设计与优化

本文研究了一种与直流母线连接的单相双向并网逆变器，以及光伏装置和蓄电池储能系统。讨论了该系统的设计及其控制机制。确定了合适的组件，并在SIMULINK环境中实现了系统。直流链路电压由电池控制，这使得提供给逆变器的参考电流不确定。这个自由参数为优化目的留下了空间。本文研究了当前能源市场上既存在可变价格合同，也存在现货价格捆绑合同的情况下的电价优化问题。消费者在使用电池储能系统时可以从这些类型的合同中受益。优化的结果和系统的全面经济分析为本工作画上圆满的句号。进一步分析了给定系统输入参数下电池和逆变器的最佳尺寸。最后进行了灵敏度分析，研究了这些参数的影响。
