Advanced Power Electronics and Controllers for Renewable based Residential Energy Storage Systems

随着可再生能源的出现，将间歇性能源转化为可用能源成为一个新的挑战。电力转换器通常用于连接电网、可再生能源和储能系统等负载和电源。与功率转换器类似，负载得到了改进，具有更高的效率。这些负载使用开关技术，使其成为非线性负载。这种非线性会导致输入电流变得非线性，从而导致电压谐波。这种电压质量恶化可能会损害医院设备等敏感负载，并可能导致违反标准。另一方面，逆变器有过电压、过电流等有害条件的保护，这可能会导致第二个问题，即保护系统的错误故障检测。本研究的目的是设计和实现鲁棒控制器，以避免此类问题，并协调控制器和安全保护算法，同时遵守法规和标准。本研究项目预计从基本控制概念和设计到控制器在公司现有逆变器上的实现和测试，预计需要12个月的时间。该公司将参与研究项目的各个步骤，包括通过后续报告(S)进行咨询、审查模拟结果、原型实施，并为可能的工业设计修改和实施提供指导。

With the advent of renewable resources, the conversion of the intermittent energy into usable form has became a new challenge. Power converters are normally used to interconnect the load and sources such as grid, renewables and energy storage systems. Similar to power converters, the loads were improved to have higher efficiencies. These loads use switching techniques that make them nonlinear. This nonlinearity causes the input current to become nonlinear which leads to voltage harmonics. Such voltage quality deterioration may harm sensitive loads such as hospital devices and may cause standard violations. On the other hand, inverters have protection system against unwanted/harmful conditions such as over-voltage and over-current which can lead to the second problem that is false fault detection by protection system.This research aims to design and implement robust controllers to avoid such problems and coordinator between controller and safety protection algorithm while complying with codes and standards. This research project is expected to take 12 months starting from the basic control concept and design to the implementation and testing of the controller on the company's existing inverters. The company will be involved in steps of the research project including consultations through follow-up report(s), review of simulations results, prototype implementations, and providing guidance for possible industrial design modifications and implementations.
