Special Issue on Optimal Integration of Renewable Energy Generation in Electrical Distribution Systems
Submission Date: 2017-07-21

Distribution networks are undergoing a radical transformation, due to several factors which contribute to the evolution of distribution networks into the new concept of smart grid but also greatly influence the grid planning and operation. More specifically, the new distribution grid will be characterized by i) a massive penetration of dispersed generation units, ii) the adoption of energy storage technologies for providing services to the grid, iii) the active participation of end users to grid operation, and iii) the use of information/communication technologies which enables the information exchange between all the grid resources. With reference to the first point, the characteristics of electrical distribution systems have been significantly modified due to the presence of more and more renewable generation units, mainly wind and solar systems. In recent years, the number of renewable generation units connected to distribution networks has continued to grow, and projections are that this process will continue in the future. The reason for this trend is to be found in the increased interest in energy saving and reduction of environmental impact. Furthermore, the technological evolution and increased customer demand for highly reliable electricity provide incentives for the proliferation of generation units connected to distribution systems that are close to the customers. However, these renewable generation units pose many challenges to grid operators due not only to the variability of their energy sources but also to their integration into the distribution network. Distribution systems, in fact, have been designed traditionally with the assumption of passive networks. The presence of generation units makes them active, thereby involving new technical considerations to be addressed for their planning and operation. This new, stimulating context requires original research on renewable energy generation in order to analyze their impact on the grid, find enhanced integrating solutions, and even improve grid operation thanks to their presence. This special issue includes all aspects related to the planning and operation of these systems as well as specific topics such as control of the interfacing static converters, power-production forecasting methods, exploitation of new technologies, and provision of services. Discussions on market or policy issues, related to the practical integration of these systems, will also be given consideration for publication. Research projects involving cooperation among researchers from academia, industries, and government will be also welcome to foster interactions among stakeholders. Potential topics include but are not limited to the following: Advanced modeling for system planning Advanced modeling for system operation Modeling for ancillary services provision Advanced technologies in wind and solar generators New control techniques and structures of power electronics interfaces for wind, PV, and other renewable sources Solar and wind power-production forecasting Integration of renewable energy generators and storage systems Role of renewable energy sources in smart grids Reliability aspects Advanced technologies in wind, solar, hydro-, and fuel cell generators Design and implementation of isolated hybrid microgrids Parallel operation of microgrids Power quality problems Actual implementations Market and policy issues Authors can submit their manuscripts through the Manuscript Tracking System at http://mts.hindawi.com/submit/journals/je/electrical.engineering/ammi/.

Special Issue on Thermophysical Characterization of the Behavior of Phase Change Materials
Submission Date: 2017-07-28

Improving the efficiency of renewable energy sources addresses the need to decrease the energy environmental impact, the lack of energy availability, and the increasing costs of energy. This concern is critical in rural communities, where the electricity and fuel grids could be underdeveloped with respect to urban areas. Public buildings like primary schools, small health centres, municipal offices, and so on of the inland regions in developing countries present a need of heat supply due to its climate. The coverage of this energy demand should be performed by high efficiency energy systems with near-zero electricity consumption and by the use of renewable energies. Phase change materials (PCM) are used to increase the efficiency of heating energy systems because the thermal energy storage through PCM is capable of storing and releasing large amounts of energy. Their major drawback is the low thermal conductivity, which reduces the rate of heat transfer during the melting and solidification cycles. The same drawback concerns the heat transfer fluids commonly used to charge/discharge the energy of PCMs. However, further theoretical and experimental research investigations on its effective energy transport and storage properties, and on its performance under operational conditions, are needed to really boost its energy efficiency. Several selected pairs should be characterized for its application in low/medium temperature heating systems. Research on their energy transport and storage properties will be performed by means of high-precision techniques. This line of research addresses at least two interdisciplinary scientific and technological fields such as new fluids and materials from renewable sources and high efficiency energy systems. Experimental, theoretical, and computational approaches are used to face up the societal challenge of improving the quality of public services offered to the community in rural areas with low availability of energy grids. Potential topics include but are not limited to the following: Selection and preparation of PCMs for its application to boost the energy efficiency of low-medium temperature storage systems for refrigeration/heating applications Experimental determination and theoretical modeling of the reliable thermodynamic and transport properties (density, heat capacity, heat of fusion, viscosity, thermal conductivity, and convective coefficient) of PCM in the higher temperature range and higher pressure Experimental characterization and computational simulation of the heat exchange rate PCM storage systems between selected pairs of composites/PCM at a laboratory level Experimental test and computational simulation of the energy efficiency of a demonstrative compact space heating prototype with renewable energy supply and equipped with nanomaterials at a preindustrial level Authors can submit their manuscripts through the Manuscript Tracking System at http://mts.hindawi.com/submit/journals/je/chemical.engineering/tccm/.

Special Issue on Advances of Unconventional Flow and Transport in Petroleum and Chemical Engineering
Submission Date: 2017-08-25

Correct understanding of flow, heat, and mass transport in chemical and petroleum engineering is very important for the design and optimization of processes. In the past decades, fine oil recovery and fine chemical industry have demanded a better understanding of nonlinear flow and transport behavior, for example, by multiphysical coupling, which is beyond the conventional theories. Developments in theories, methods (both in experiment and in modeling), and technologies have brought about numerous achievements in the past ten years for the unconventional flow and transport in such engineering applications. This special issue therefore is aiming at a collection of state-of-the-art advances of unconventional flow and transport in chemical and petroleum engineering. We emphasize unconventional ones either in study subject or in methodology. Particularly, multiphysiochemical coupling or multiscale transport in complex systems is welcome. Potential topics include but are not limited to the following: Non-Darcy flow in petroleum and chemical engineering Nonlinear diffusion in organic and inorganic microporous media Thermohydromechanical coupling in tight rocks Enhanced oil/gas recovery for unconventional resources Multiscale modeling and analysis Authors can submit their manuscripts through the Manuscript Tracking System at https://mts.hindawi.com/submit/journals/je/chemical.engineering/unfl/.

Special Issue on Energy Management of Distributed Energy and Microgrid
Submission Date: 2017-09-08

With the development of distributed energy (e.g., wind, solar, and biogas) and low-carbon technology, the current energy systems are undergoing a significant transformation including new analytical methods of optimization, planning, and control. The objectives of energy management of distributed energy and microgrid (DEM) include cost savings and climate protection. Microgrid is an effective means of integrating multiple sources of distributed energy and improving the economy, stability, and security of energy systems, facilitated by the development of science combined with the promotion of politics and social economy. Taking into account the volatility of distributed energy, optimal power supply, energy conversion and dispatch, and load response should be coordinated in the energy management of DEM. From the perspective of energy types, energy management of DEM involves electricity, heat, gas, and renewable energy. Properly managed DEM may make contributions to security and stability from the building level to energy network level. In addition, due to the uncertainty of renewable energy and demand side (e.g., electric vehicles) , it is quite a challenge to form an efficient energy management approach. The energy management of DEM helps the analysis of temporal and spatial properties of various components and energy coupling mechanism, which plays a key role in improving the comprehensive energy efficiency of energy systems. The purpose of this special issue is to publish high quality articles on the topic of energy management of DEM, containing original research results and review articles of exceptional merit, and it will let the readers of this journal know more about this field of study. Potential topics include but are not limited to the following: Modelling and analysis methods for DEM Energy management of DEM Energy generation and distribution management in DEM Energy storage Distributed renewable energy supplies Demand side response in DEM Information and communication technologies in the energy management of DEM Economic analysis, new business models, and markets for energy management in DEM Environmental and policy impact of management in DEM Case studies and best practices for DEM Authors can submit their manuscripts through the Manuscript Tracking System at https://mts.hindawi.com/submit/journals/je/electrical.engineering/dem/.
