TL;DR: In this paper, a new hybrid method called PHANN based on an Artificial Neural Network (ANN) and PV plant clear sky curves is proposed and compared with a standard ANN method, which can play a fundamental role in solving problems related to renewable energy source (RES) integration in smart grids.
Abstract: The main purpose of this work is to lead an assessment of the day ahead forecasting activity of the power production by photovoltaic plants. Forecasting methods can play a fundamental role in solving problems related to renewable energy source (RES) integration in smart grids. Here a new hybrid method called Physical Hybrid Artificial Neural Network (PHANN) based on an Artificial Neural Network (ANN) and PV plant clear sky curves is proposed and compared with a standard ANN method. Furthermore, the accuracy of the two methods has been analyzed in order to better understand the intrinsic errors caused by the PHANN and to evaluate its potential in energy forecasting applications.

TL;DR: A big data computing architecture for smart grid analytics, which involves data resources, transmission, storage, and analysis, and a hybrid approach is adopted for the optimization including GA for storage planning and a game theoretic inner optimization for daily energy scheduling.
Abstract: The development of smart grid brings great improvement in the efficiency, reliability, and economics to power grid. However, at the same time, the volume and complexity of data in the grid explode. To address this challenge, big data technology is a strong candidate for the analysis and processing of smart grid data. In this article, we propose a big data computing architecture for smart grid analytics, which involves data resources, transmission, storage, and analysis. In order to enable big data computing in smart grid, a communication architecture is then described consisting of four main domains. Key technologies to enable big-data-aware wireless communication for smart grid are investigated. As a case study of the proposed architecture, we introduce a big-data- enabled storage planning scheme based on wireless big data computing. A hybrid approach is adopted for the optimization including GA for storage planning and a game theoretic inner optimization for daily energy scheduling. Simulation results indicate that the proposed storage planning scheme greatly reduce

TL;DR: The Energy Box as discussed by the authors is proposed as a 24/7 background processor operating on a local computer or in a remote location, silently managing one's home or small business electrical energy usage hour-by-hour and even minute-byminute.
Abstract: The Energy Box is proposed as a 24/7 background processor operating on a local computer or in a remote location, silently managing one's home or small business electrical energy usage hour-by-hour and even minute-by-minute. It operates best in an environment of demand-sensitive real-time pricing, now made feasible via ‘smart grid’ technology. We assume that, in time, virtually every electrical device in a home or small business will be controllable from the Energy Box. There are multiple motivations for an Energy Box: (1) By delaying or pushing forward various uses of electricity (e.g., space conditioning), widespread use of the Energy Box could ‘shave the peaks and fill in the valleys of demand,’ thereby reducing the need for capacity expansion in electrical power generation and distribution; (2) The system should result in reduced electrical energy costs to the consumer; (3) The system supports local generation, storage and sale of electricity back to the grid; (4) The system supports graceful reduction...
