Towards a Smarter Grid - A short course jointly organized by Power Engineering Division, School of Electrical and Electronic Engineering, NTU and IEEE Singapore Section - (Last updated on July 11, 2013) Introduction A large part of Singapore transmission and distribution networks has already incorporated automated monitoring and control systems, allowing the flow of energy and information in real-time. This has made Singapore s energy system highly efficient and reliable. Consumers in Singapore experience fewer disruptions of energy supply and even when disruptions do occur, they are usually very short in duration. However, it is important to make the energy system more intelligent by extending its reach to consumers to meet their needs and enable faster responses to changes in energy demand and supply. Smart grid is the extension of the microgrid through the seamless integration of demand side in the management of the grid infrastructure. Integration of demand side in smart grid is vital for stabilizing and securing power supply system during transmission from unstable sources of electricity or disruptions. Figure 1 shows the components of a possible smart grid at the distribution voltage level. The smart grid is a distributed, yet integrated, system that will automate the energy chain and empower consumers to participate directly or indirectly in the generation and consumption of energy. The advanced metering infrastructure (AMI) forms the backbone of an efficient smart grid system that will facilitate versatile and flexible monitoring and control capabilities. Smart grid can swiftly obtain and process the output and demand data, then automatically optimize or secure the demand and supply balance. The smart grid will incorporate various advanced technologies such as demand side management, demand response management, energy efficiency system and electric vehicle management. Figure 1: Smart grid architecture The previous course conducted in August 2010 presented the research and development work of the Microgrid Energy Management System (MG-EMS) project at NTU. Basic concepts of the MG-EMS, renewable energy sources, power converters, and their interface through sensing and communication technology were discussed. Research works at NTU, specifically the design of software algorithms and control schemes that are used for minimizing the schedule cost or maximizing the revenue of MG-EMS were also reported. Moving forward, the incorporation of the demand side with the MG-EMS will enable advanced smart grid technologies that can achieve energy reductions through an efficient use of electrical energy. Furthermore, the integration of MG-EMS with active consumers through home and building energy management systems will enable the smart grid to control and optimize the scheduling 1
of energy used by the loads in order to minimize overall costs of electricity and respond to incentives from the service providers to curtail loads at times of peak or off-peak demand. Research findings of the recently completed Shore Power project as well as on-going projects such as Cost-Benefit Analysis for Smart Grid in Singapore, Virtual Power Plant and Intelligent Energy System at NTU will be reported. This course will discuss the challenges in the integration of renewable energy sources and the application of power electronic converters in smart grids. The advancement in energy management system for smart grid such as optimal sizing of battery banks and the virtual power plant concept will also be covered. The course will present advanced smart grid technologies with a focus on the consumer side typically homes, buildings and electric vehicles. While courses related to the smart grid technologies have been conducted in both the United States and Europe, this course is unique in Singapore and the region as it showcases laboratory prototypes for testing new devices, control schemes and market policies/standards/rules related to the future development of smart grids. Course Objectives The urgency to drive an overhaul of grid infrastructure has seen governments, industries, and electric utilities around the world coming together to stimulate the development of the smart grid technology. These initiatives are designed to integrate clean energy technologies, improve the reliability of the electrical grid, reduce costs through increased operating efficiency for utilities, improve energy efficiency through consumer participation and prepare the grid for the integration of electric vehicles. Pike Research forecasts that smart grid infrastructure, including grid automation upgrades as well as smart metering, represents a huge market opportunity and will attract $200 billion in worldwide investment between 2008 and 2015. The smart grid is transforming the electric industry from a centralized, producer-controlled network to the one that is less centralized and more consumer-interactive. The basic concept of the smart grid technology is to integrate monitoring, control, analysis and two-way real-time communication to the electric transmission and distribution system to improve the efficiency of the system while reducing the energy consumption. The smart grid will allow utilities to distribute electricity around the system as efficiently and economically as possible. It will also allow and encourage the consumers to use electricity as economically as possible while reducing consumption. The smart grid builds on many of the technologies currently employed by utilities but incorporates communication and control capabilities that will optimize the operation of the entire electrical grid. The smart grid is also positioned to take advantage of new intelligent technologies, such as distributed generation, demand side management, demand response management, home/building energy management systems, plug-in electric vehicles, and many more as shown in Figure 2.

This course aims to introduce how smart grid technologies enhance the efficiency of the energy supply system. It will discuss the basic concepts of renewable energy sources and the application of power electronic converters in overcoming their potential challenges. Current advancements in energy management system for the smart grid will also be discussed. Emphasis will be placed on optimal sizing and coordination of energy storage systems in a smart grid. The course will also present innovative inclusion of consumer energy management systems in the smart grid to provide the ability for demand side management and demand response management to ensure an efficient and prudent use of energy. These consumer energy management systems provide a technical solution that empowers utilities and consumers to make homes and buildings more energy efficient. Typically, home, building and electric vehicle energy management systems will allow consumers and utilities to manage energy usage and reduce peak demand without sacrificing consumer comfort and convenience while reducing the environmental footprint. Towards the end of the course, demonstrations including renewable energy sources, power converters, battery management systems, home and building energy management systems, shore power, and electric vehicles will be performed. 3
