The traditional electrical power grid is currently evolving into the smart grid. Smart grid integrates the traditional electrical power grid with information and communication technologies (ICT). Such integration empowers the electrical utilities providers and consumers, improves the efficiency and the availability of the power system while constantly monitoring, controlling and managing the de...

Smart grid security is crucial to maintain stable and reliable power system operation during the contingency situation due to the failure of any critical power system component. Ensuring a ‘secured smart grid’ involves with a less possibility of power grid collapse or equipment malfunction. Due to lack of the proper ‘security measures’, a major blackout may occur which can even lead to a cascad...

† Fuji Electric Co., Ltd. opment Organization (NEDO) for a period of 5 years beginning in 2003, and has amassed a proven track record for developing and evaluating “microgrid control technology” that balances the supply and demand of energy within a regional grid consisting primarily of renewable energy sources such as solar power, wind power and biomass power. Combining its accumulated advance...

Power supply in the 21st century is facing more and more challenges, e.g., environment protection, energy shortage etc, such that the techniques related to power supply imminently need to be promoted. Complying with the development of green and lowcarbon economy, the concept of Smart Grid has been proposed. By and large, Smart Grid may be regarded as an important application of the techniques o...

This paper presents the survey of the smart grid technologies, including the background, motivation and practical applications. The driving forces for the smart grid technologies are presented, including the blackout, global energy crisis and environmental protection requirement. The key technology issues for building the smart grid are discussed. The crucial elements of the smart grid and thei...

The increasing complexity of the conventional grid due to population growth, advancement in technology, and infrastructures are the factors that contribute immensely to instability, insecurity, and inefficiency of the use of electrical energy. To overcome the problems, the environmental energy sustainability calls for the use of renewable energy for sustainability of power supply. Intermittency...

Smart city is an attractive way of making the city more livable through intelligent solutions that are enabled by information and communication technology. Regarding the lighting system, it achieves the perfect balance between beautiful city ambience and preserving the darkness that makes cities more livable. As a smart city component, a public lighting system offers much more than light itself...

Intelligent information systems are necessary to improve power grid operations. The current trend reveals the deployment of smart meter at consumer sites as the energy provider’s starting point to grid modernisation. Smart meters are considered as a core element in most of the smart grid projects. The smart metering system is designed to collect and transmit detailed consumption data. Detailed ...
