A solar power plant including a power conversion system and a method of controlling the power conversion system. Implemented in a DC / AC inverter, the plant includes photovoltaic modules (PV modules) arranged in arrays connected to a respective DC / DC converters. A power collecting grid interfaces between the DC / DC converters and the DC / AC inverter. The method includes monitoring the performance of each PV array by adjusting the voltage level of each interface between a PV array and the corresponding DC / DC converter, and includes monitoring the output power of each DC / DC converter as a feedback for the regulating.

The future of the utility industry will be defined by how its leaders can transform the grid from a “passive” network of cables, wires, poles, and other hardware to a self-aware and fully controllable grid system—an Intelligent Grid System (IGS). We will discuss a novel set of design guidelines for utilities (and other industries) to build their own Open Intelligent Grid System with the lowest possible risk and cost, while achieving the architectural criteria, technical features and functions required. We will discuss how to avoid the dead ends to which limited design and architecture can lead, and we will lay out the design solutions that will overcome the business and technical challenges posed by an array of technology products and business imperatives. Using IGIN (Intelligent Grid Interface Node), one can integrate or connect hybrid networks for different purposes, such as power electric industry, telecommunication, computer network, and Internet.

Systems, apparatus, and methods are presented to transfer energy between an energy storage device (ESD) at an electrified vehicle (EV) and an AC or DC external load such as an electric grid, appliance or power tool. A portable EVETA can engage an EV charge inlet couple an EV, and can provide an AC outlet, a grid interface and a DC connector for coupling external loads. An EVETA can be used at a remote construction site or campsite to power high current equipment, obviating the need to transport an electric generator. An EVETA can be configured for data and control communication with the EV to coordinate energy transfer. An EVETA can receive a predetermined ESD state of charge limit so that the transfer process can be terminated to preserve sufficient charge for EV return to a desired destination. A human machine interface enables user input reception and information display.

The invention belongs to the technical field of nondestructive detection, and relates to an automatic scanning-based cellular core sandwich structure ultrasonic imaging detection method. The method is characterized in that defect discrimination and ultrasonic imaging are carried out through establishing corresponding transition functions by using the reflection echo signals of incident pulse ultrasonic waves with different wavelengths in a sheath / cellular core connecting layer, a cellular core connecting layer / cellular wall and a cellular core connecting layer / cellular grid interface. Ultrasonic automatic scanning imaging detection of different cemented and welded cellular core sandwich structures is realized through selecting different incident pulse ultrasonic wave frequencies, an energy transducer and an acoustic beam diameter thereof, scanning stepping, acoustics coupling modes and ultrasonic automatic scanning devices. A practical detection effect shows that the method greatly improves the detection sensitivity and resolution and the detection ability of a cellular core structure, allows defects and combination conditions between the sheath / cellular core, the sheath / connecting layer and the connecting layer / cellular grid, and greatly improves the detection reliability.

Welding system and method permit exchange of data with Smart Grid monitors and / or controllers. The welding systems include a welding power supply configured to convert power between the power grid and the welding power supply. A grid interface cooperates with control circuitry to transmit data to and / or from the grid monitors and / or controllers on the grid side. The control circuitry may control operation of the welding power supply based upon data from the grid. The system may include power generation devices (e.g., engine-drive generators) and energy storage devices (e.g., batteries). The control circuitry may control operation of such devices, the exchange of power between them, and the draw of power from the grid or the application of power to the grid based upon the data exchanged with the grid monitors and / or controllers.

The present invention includes a method, system, and computer-readable medium for calculating a social graph using a social utility grid interface. The method includes the following steps. First, collecting one or more types of communication data. Next, inputting the one or more types of communication data into a social utility grid infrastructure. The social utility grid infrastructure analyzes the input data to determine a multi-dimensional first-order social graph by: (1) normalizing each of the one or more types of communication data; (2) representing the each of the one or more types of communication data as a vector; (3) calculating a Euclidean Norm; and (4) generating the multi-dimensional first-order social graph. Then, providing the multi-dimensional first-order social graph to one or more software applications.
