Smart grid is an important platform for the exploitation of renewable energy resources and maintaining/improving the reliability of power grid. Challenges have been identified during the construction of smart grid, which calls for novel simulation, computation and data management technologies. For example, as the size of power systems continue to increase, new computational tools are needed to co-simulate...
Interest in the implement of vanadium redox-flow battery (VRB) for energy storage is growing, which is widely applicable to large-scale renewable energy (e.g. wind energy and solar photo-voltaic), developing distributed generation, lowering the imbalance and increasing the usage of electricity. However, a comprehensive economic analysis of the VRB for energy storage is obscured for various commercial...
With many applications of internet of things (IoT) technology in smart grid, the power internet of things (PIoT) faces new issues in security, especially in sensing applications. This paper illustrates perspective of the PIoT and its security, and gives the security framework, security policies and appropriate countermeasures. Since the PIoT is a huge complex cyber-physical network, the study on the...
The smart grid is an electric power grid-to provide "electricity with a brain" that uses information and communications technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity. Substation,...
The Smart Grid includes power generation, transmission, substation, distribution utilization and dispatch, is an international power industry to meet future challenges (global resources and environment question) of common choice. The first half of 2011, the global Internet digital distribution institution (IANA) announced that global IPv4 addresses pool has run out, IPv6 times to come. To support...
The Internet of Things (IoT) has been considered as the third revolution in the digital technology after the computer and the Internet, and it brings significant advantages to smart grid. Disaster prediction and prevention of power-lines is one of the most difficult problems for electricity transmission companies. Advanced sensing and communication technologies of IoT can effectively avoid or reduce...
Smart home has become a popular application all over the world. However, the service to interact with smart grid, and the service to guide residents utilize power, are ignored. In this paper, we propose an effective converged service oriented architecture (CSOA) to give a solution for supplying a converged service in smart homes. This architecture not only supports diversified service integrated with...
