The overhaul of electrical power grids has been a top priority for many governments and its national utility companies worldwide for the last 20 years. Innovation such as adopting IT technology has been actively sought to accelerate this process. The new grid, also known as a Smart Grid, promises to improve energy efficiency. In addition, the Smart Grid is less harmful to the environment, improves the quality of life, and can boost competitiveness. The Smart Grid integrates information and communication technologies and takes the behavior of suppliers and consumers in an automated fashion to improve the efficiency, reliability, and security in generating and distributing electricity. The need to integrate and distribute energy resources, which can provide a more reliable, energy efficient supply of electric power has further prompted the development of the Smart Grid. To successfully develop the Smart Grid, many challenges must be overcome, which in turn gives rise to many opportunities.
In this forum, we will focus on three perspectives of the smart grid, i.e., IT technology, energy technology and regulatory policies. Chin-Wen Liu will review a wide-area measurement system for power grid real-time monitoring. Ming-Whei Feng will introduce the way of incorporating IoT technologies to smart grid. Edwin Liu will address issues related to charging a plug-in electric vehicle into a smart grid. Chao-Shun Chen will present an advanced distribution automation system for smart grid. Faa-Jeng Lin, Jin-Shyr Yang and Gary W. Chang will discuss the development, migration and power quality of the Smart Grid, respectively.

Incorporate Internet of Things Technologies to Smart Grid to Enable Smart Energy System and Services
Ming-Whei Feng, Smart Network System Institute, Institute for Information Industry, Taiwan
Smart energy signifies a grid that incorporates Internet of things technologies (IOT) consisting of sensors / actuators, sensor network, information gateway and analytics engine, to allow rich sensing, control, management, and negotiation capabilities within the grid as well as between grid and customers.
A smart energy system needs to fully integrate with information & communication technologies (ICT) such as Internet of things to energy grid system to make it practically useful, scalable, and extensible through the energy distribution system, from businesses and homes and back to the sources of energy. Since a smart energy system incorporates rich ICT capabilities, the utility subsystems and major components are interconnected with a two-way flow of information and energy across the network, including information on pricing. In addition, the smart energy system has more advanced intelligent functions, making use of proactive analytics and automation to transform data into insights and efficiently manage resources.
The above describe smart energy system will provide significant value propositions to the smart grid, including making the grid more manageable with enhanced effectiveness and efficiency, as well as providing new value added service opportunities. In this presentation, we will describe the application trend and technology requirements associated with the smart energy system. We will also illustrate some global application cases. We will then present III’s energy ICT and Internet of things technologies, and successful energy application cases.
Plug-in Electric Vehicle and Smart Grid
Edwin Liu, Vice President, Quanta Technology, USA
“Transportation Electrification” has been identified as one of the key domains-of-focus for Smart Grid effort. Effective integration of electric transportation into smart grid will depend on the rate of PEV proliferation, consumer charging behavior, technology, standard development, and the readiness of power distribution systems. In the short-term, utilities will be concerned with deploying basic smart charging programs including simple demand side management techniques that offer their PEV customers with cost optimization “grid friendly” methods of charging their PEVs. Utilities, on the other hand, will have to strengthen their distribution systems to handle the coming demand increase due to the integration of PEVs. In the long-term, we should manage the transportation electrification through a holistic approach. Besides changing infrastructure and standardization deployment, we should also focus on the overall strategy that considers DERs and distribution system management through information and analytics integration. In this presentation, I will address immediate issues related to controlled and un-controlled PEV charging, and their impacts on power distribution systems. I will also discuss going-forward strategy on how analytical methods shall help in building smart distribution grids that allow effective integration of PEVs.
