Abstract

This paper proposes a grid connected PV-Ocean wave hybrid renewable energy (RE) power generation system with battery as an energy storage device. Ocean wave conversion system is designed by combining an oscillating wave column (OWC) converter based wave chamber, which fed power to a wave turbine that is coupled to a permanent magnet synchronous generator to generate ocean wave power. In order to build PV array, total five KOYCERA KC85T-87W PV model is designed in MATLAB and all the models are connected in series in combination with one another. To maintain constant voltage at DC link capacitor storage device battery is used. A proportional integral (PI) controller based Buck-Boost converter is used to control the charging and discharging state of battery to maintain constant DC link voltage. A three-phase voltage source inverter (VSI) is designed to integrate the proposed hybrid system with the grid. Simulation using MATLAB/Simulink has been conducted to evaluate the performance of the system.

并网电池储能波能与光伏混合可再生能源发电建模

提出了一种以电池为储能装置的并网光伏-海浪混合可再生能源发电系统。海浪转换系统是通过结合基于振荡波柱(OWC)转换器的波室来设计的，波室向波浪涡轮机供电，波浪涡轮机与永磁同步发电机耦合，产生海浪能。为了构建光伏阵列，在MATLAB中设计了总共5个KOYCERA KC85T-87W光伏模型，并将所有模型串联起来进行组合。为了保持直流链路的恒定电压，使用了电容存储装置电池。采用基于比例积分(PI)控制器的Buck-Boost变换器控制电池的充放电状态，以保持直流链路电压恒定。设计了一种三相电压源逆变器(VSI)，将所提出的混合系统与电网相结合。利用MATLAB/Simulink进行了仿真，对系统的性能进行了评估。
