Patent number: 11848624Abstract: This invention proposes a single-vector-based finite control set model predictive control for two parallel power converters, which adopts a centralized control structure to achieve accurate control of overall performance. It establishes predictive models for line currents and three phase-circulating currents and constructs a novel cost function that uses these currents as performance indices to implement the predictive control algorithm based on the proposed predictive models. The invention proposes dynamic weighting coefficients and adjustment principles to improve system control performance. A finite set output signal matrix containing important characteristic information of all alternative vectors is constructed to avoid redundant calculations in each control horizon, reducing computation time during practical implementation.Type: GrantFiled: March 28, 2023Date of Patent: December 19, 2023Assignee: Nanjing University of Science and TechnologyInventors: Zhiyong Zeng, Li Yang, Zhen Cui, Xiaoliang Jin, Lei Li, Diming Zhang

Patent number: 11009012Abstract: Disclosed is a combined energy supply system of wind, photovoltaic, solar thermal power and medium-based heat storage, capable of storing the energy which would have been “abandoned wind” and “abandoned light” temporarily in the form of heat by medium-based energy storage. Heat is released during peaks in the power grid to generate power, which serves the function of adjusting the peaks in the power grid. With the medium-based energy storage, unstable photovoltaic electric energy can be converted into stable heat energy output when a relatively large fluctuation occurs in wind and photovoltaic power generation, and therefore the stable supply of energy sources can be guaranteed efficiently. Furthermore, a second heater can also be used for heating the low-temperature media outputted by a first medium tank (100), or a third heater is used for heating water in a heat exchanger (500), and therefore the energy storage of the medium or the heating efficiency of the heat exchanger is improved.Type: GrantFiled: December 31, 2014Date of Patent: May 18, 2021Assignee: SHENZHEN ENESOON SCIENCE & TECHNOLOGY CO., LTDInventors: Zhiyong Zeng, Xiaomin Cui, Bei Huang

Publication number: 20210088032Abstract: The invention relates to an improved Brayton concentrated solar power generation method, which belongs to the technical field of solar power generation. The method performs the following steps under normal pressure or micro positive pressure: (1) the heat storage medium enters the heat collection device from the low-temperature tank; (2) the sunlight is collected to the heat collection device to transform the heat storage medium into the high-temperature heat storage medium; (3) the high-temperature heat storage medium enters the heat exchanger and exchanges heat with the power working medium; (4) the high-temperature power working medium after heat exchange enters the turbine generator set to provide power generation. Based on the method, the invention also provides a matched power generation system. Adopting the method and device of the invention for power generation has the advantages of low cost, easy construction and maintenance, high efficiency, less restriction, etc.Type: ApplicationFiled: January 30, 2018Publication date: March 25, 2021Inventors: Zhiyong ZENG, Xiaomin CUI, Ke LI
