The smart grid is the next generation electrical grid, which will enable the smart integration of conventional, renewable and distributed power generation, energy storage, transmission and distribution, and demand management. The benefits of smart grid include enhanced reliability and resilience, higher intelligence and optimized control, decentralized operation, higher operational efficiency, more efficient demand management, and better power quality. However, the large-scale deployment of smart grid without proper utilizations can cause new dimension of threats, particularly in critical infrastructures that are highly dependent on the availability of electricity.
Modern telecommunications will play a vital role in the smart grid as many of its operations and applications require vast amount of information to be communicated between entities in real-time for timely monitoring and control. Beyond smart grid, telecommunications are also an important enabler of human-to-human, human-to-machine, and machine-to-machine connectivity in other smart systems such as smart buildings, transportation and healthcare. These connections and interactions between networked entities will make possible the seamless provision of a wide variety of new services that provide a way of life that is secure, convenient, comfortable, and sustainable in future smart cities.
