Among different technologies, the Wave Energy Conversion (WEC) represents an efficient, clean and sustainable source for generating electricity, however creating distributed generation plants with Wave Energy Potential (WEP) necessitates extremely careful estimation. Therefore, a new model using five components of Fourier series has been presented for WEP estimation. The model helps reduce the imprecision in the wave estimation due to the time resolution of wave data, permits to emulate the buoy movement when a wave reaches it (hydrodynamics studies), facilitates in the emulation of the linear electric generator magnets movement located inside a powerbouy system (electromagnetic simulations) and helps obtain the correct generated voltage curve shapes and power quality with the aim of designing and selecting the electrical components to connect the microgrid by wave power to the power system. The model is a function of significant height and periodicity of the waves and offers an evidence for a better WEP estimation. Irregular wave profile is very important to predict the voltage and power quality supplied by the powerbouy. When the irregular wave profile is ignored, WEP estimations could exceed 90% and produce false expectations of electric power generation and incorrect sizing of electric components for the microgrid by wave power. Thus, true WEP estimation can prove to be a good investment decision tool to develop wave energy plants. For proposed model validation, the results of an assessment of wave energy in 25 different geographic coordinates of the Mexican coast, based on wave motion profile, suggest that the Mexican Pacific side is suitable for wave power plant development, 100–500 kW for each installed powerbouy in such points. Consequently, this work contributes to obtaining new techniques in WEP estimation based on wave parameters in order to get electrical parameters for true electrical power. Thus, search for technological development for the electrical equipment is required to install for its harvest in wave microgrid system.

通过波动仿真建模评估Powerbouy系统发电的波动功率

在不同的技术中,波浪能转换(WEC)代表了高效,清洁和可持续的发电来源,但是要创建具有波浪能势(WEP)的分布式发电厂,则需要进行非常仔细的估算。因此,提出了一种使用傅里叶级数的五个分量的新模型进行WEP估计。该模型有助于减少由于波浪数据的时间分辨率而引起的波浪估计中的不精确性,允许在波浪到达时模拟浮标运动(流体动力学研究),有助于模拟位于动力舱内部的线性发电机磁体运动系统(电磁模拟),并有助于获得正确的生成的电压曲线形状和电能质量,目的是设计和选择电气元件以将微电网通过波功率连接到电力系统。该模型是波的高度和周期性的函数,并为更好的WEP估计提供了证据。不规则的波形图对于预测Powerbouy提供的电压和电源质量非常重要。如果忽略不规则的波形,则WEP估计值可能会超过90%,并且会产生错误的发电预期,并且会产生波浪功率导致微电网的电气组件尺寸错误。因此,真实的WEP估计可以证明是开发波浪能发电厂的良好投资决策工具。对于建议的模型验证,根据波浪运动剖面在墨西哥海岸的25个不同地理坐标中对波浪能进行评估的结果表明,墨西哥太平洋一侧适合波浪发电厂的发展,在这些点上,每个已安装的动力舱都需要100-500 kW。因此,这项工作有助于获得基于波参数的WEP估计中的新技术,从而获得真实电功率的电参数。因此,需要寻找用于电气设备的技术开发以将其收获安装在波浪微电网系统中。这项工作有助于获得基于波参数的WEP估计中的新技术,从而获得真实电功率的电参数。因此,需要寻找用于电气设备的技术开发以将其收获安装在波浪微电网系统中。这项工作有助于获得基于波参数的WEP估计中的新技术,从而获得真实电功率的电参数。因此,需要寻找用于电气设备的技术开发以将其收获安装在波浪微电网系统中。
