摘要： A method for forecasting reduction in sunlight intensity due to cloud cover at a photovoltaic power plant is described. The method comprises determining characteristics of one or more clouds from sensors surrounding the photovoltaic power plant. The cloud characteristics are used to create a 3D map of the clouds. The 3D map in combination with information on the angle of the sun is used to create a 3D projection on the surface of the earth, resulting in a 2D surface irradiance map. The 2D surface irradiance map may be taken in successive projections or used in combination with wind speed data to forecast fluctuation in irradiance at the photovoltaic power plant. The forecasted reductions in power may be used to enact measures at the plant such as reducing the power output of inverters to prevent sudden fluctuations in the power output of the photovoltaic plant feeding the utility.
摘要翻译：描述了一种用于预测由于光伏电站的云层引起的太阳光强度降低的方法。该方法包括从围绕光伏电站的传感器确定一个或多个云的特征。云特征用于创建云的3D地图。 3D地图结合有关太阳角度的信息用于在地球表面上创建3D投影，从而产生2D表面辐照度图。 2D表面辐照度图可以连续投影或与风速数据组合使用，以预测光伏发电厂的辐照度波动。预计的电力下降可用于在工厂实施措施，例如降低逆变器的功率输出，以防止供电电力公司的光伏电站的功率输出的突然波动。

摘要： Methods, systems, controller devices, and computer program products for reactive power control at a renewable energy site are provided. Embodiments address dynamic performance problems associated with control loop delay and the changing modes of operation for meeting utility voltage and reactive power constraints. Provided is a method for reactive power control involving: (a) determining a site-wide reactive power command comprised by a sum of a reactive power feedforward or compensation term and an integrator term; and (b) distributing the site-wide reactive power command among inverters. Embodiments can include a reactive power control term based on the sum of a single integrator and feed-forward compensation term, an integrator anti-windup mechanism based on the status of individual inverters, a means for decreasing detrimental effects of loop delay during reactive power reference changes, and/or a means of implementing voltage and power factor limits with smooth transfer between reactive power operating regions.

摘要： Systems and methods of generating landing solutions for containers onto landing surfaces using multiple measurement points generated by a measuring device or multiple measuring devices are described. In particular, methods of analyzing the plurality of measurement and from the analysis of the data, determining the location and orientation, in the container handling equipment's frame of reference, of where to place a shipping container onto a landing surface present within the equipment's workspace are described. This location can then be used by the equipment's automation system to automatically place the shipping container onto the landing surface without the need for human input, or relatively little human interaction or input. The systems and methods are applicable to operating in a landside transfer zone as well as outside such zone, and as such would be applicable to install on any container handling equipment which can land containers on equipment from above.
