This article presents optimal strategies in the home energy management system (HEMS) integrating solar power, energy storage, and vehicle-to-grid (V2G) capability for predetermined scenarios. The proposed system aims to address the demand response schemes, both real-time pricing and emergency load curtailment, V2G mode of operation. In the interruption event, the HEMS operates in the vehicle-to-home mode to ensure supply continuity. The control algorithms are experimentally implemented on the created hardware platform of EV and home batteries, solar power, and household loads with preset priorities. Both ac and dc charging technologies for EVs are considered. The HEMS simultaneously optimizes the scheduling of charging and discharging of EVs and home battery. Results on operation under predetermined scenarios have confirmed the validity of the proposed HEMS. [ABSTRACT FROM AUTHOR]

Taking advantage of the low-cost photovoltaic (PV) energy requires overcoming several process challenges. The Triple intercell bar technology, with current source topology, is a synergic solution. This bar overcomes faulty or open contacts and surpasses the anomaly of metallurgical short circuits. In addition, an extra 10% in sunlight PV energy is possible, thanks to lower current densities dispersions. This requires modulating the day–night process current of the copper cathodes electrowinning facility. The technology ensures bypass of defective contacts and prevention or attenuation of short circuits. Moreover, the technology extends the lifetime of the electrodes and improves the energy efficiency. A concentrated parameter model, using industrial data projects the results. [ABSTRACT FROM AUTHOR]

An energy management information system (EMIS) combines software, hardware, and data to support people in their efforts to manage energy at the process, system, facility, and enterprise level, year after year. A distributed measurement and monitoring system (DMS) is a fundamental part of an EMIS; it is constituted by the meters distributed in the switchboards of the power system. This article suggests a method of assessment of a DMS based on an indicator called level of coverage (LOC). This indicator can evaluate the LOC of a single meter or of a whole system considering the classification in significant energy uses according to the standard ISO 50001. [ABSTRACT FROM AUTHOR]

Global competition and reduced profit margins often push modern manufacturing systems toward continuously operating close to their full capacity. This can cause additional stress on the components and even lead to their premature failure, which could in turn result in halt in operation, inventory buildup, potential waste, and possible need for component replacement. Sustainability has often been viewed as utilization of renewable and green energy. However, this paper puts forth an integrated framework for optimal asset and energy management in a manufacturing plant in order to promote sustainable operation. An operation strategy has been devised that minimizes the risk of component failure on the rest of the system, the operation cost, the emissions, as well as material waste due to unwanted postprocess inventory buildup. The problem formulation is nonlinear and mixed-integer in nature, with multiple objectives that at times can be contradictory. Hence, a goal programming approach is used in order to ensure that all objectives are given equal priority. [ABSTRACT FROM PUBLISHER]
