BC Hydro is one of the leaders in the North America in the implementation of Voltage VAR Optimization (VVO) in distribution systems. Several VVO projects have been commissioned during the past 12 years resulting in improved voltage regulation, losses reduction and energy savings. BC Hydro's field experience with perspective for this advanced VVO Smart Grid application along its perspective on the...
The author has had hands-on experience, from the utility perspective, of deploying AMI solutions at two different utilities: Austin Energy and now CPS Energy. Mr. Hawkins will explore the contrast in technologies between the two waves of AMI technologies, and how the latest AMI technologies would enable DR and Smart Grid strategies at CPS Energy. Mr. Hawkins will also present some of the business...
In the 21st century, China is facing the objective requirements of improving the energy structure, protecting the environment. Therefore it is necessary to develop smart grid. Combined with the development and management situation of grid in China, framework of smart grid for future research is proposed. The key issues to be resolved and feasible technical path for the construction of Chinese strong...

Information communication technology (ICT) enabling energy efficiency has been considered as the fastest way to reduce carbon CO2 generation, while replacement energy may take decades to deploy. We start observations of electricity flow in the power grid and suggest a distributed optimization of electricity usage under a hierarchical structure and propose possible direction to facilitate the communication...
In order to comprise energy efficiency for electrical devices in homes, a smart grid-base AMI (Advanced Metering Infrastructure), which checks electricity consumption and controls the electric energy used with the demand response technique, is necessary for remotely managing the load of the energy and power consumed. The smart controller calculates the amount of electricity consumed by customer on...
Demand Side Management (DSM), first referred in the US in the late 1970s, is based on the purpose of the planning, implementation and monitoring, of the activities of electric utilities to influence customer usage of electricity that will result in desired changes in the load shape experienced by the distribution system, i.e. changes in the time pattern and magnitude of the network load. The objective...
Energy efficiency, power system reliability and the environmental impact of fossil fuel plants are all drivers for more intelligent or smart grids. We discuss a Perfect Power System, a smart micro grid with system redundancy, and implement a test bed to demonstrate smart grid concepts such as demand response, onsite generation, automated lighting system control, and ambient temperature control. We...
There are many types of Energy Management Systems (EMS) that may be found in the industrial, commercial, and residential sectors. These systems range from the largest and most complex ones found in power generation and industrial plants down to the smallest and simple systems utilized by the residential consumer of energy. Independent of the magnitude and sophisication of the application, each type...
Smart grid is an intelligent power generation, distribution and control system. ZigBee, as wireless mesh networking scheme low in cost, power, data rate, and complexity, is ideal for smart grid applications. Unfortunately, almost all ZigBee channels are overlapped with wireless local area networks (WLAN) based on 802.11 specifications, resulting in significant service degradations in interference...
Increasing energy prices and the greenhouse effect lead to more awareness of energy efficiency of electricity supply. During the last years, a lot of technologies have been developed to improve this efficiency. Next to large scale technologies such as wind turbine parks, domestic technologies are developed. These domestic technologies can be divided in (1) Distributed Generation (DG), (2) Energy Storage...
The mounting pressures on conventional energy sources and recent findings on climate change have brought attention to not just how we use energy but also how we manage it and ultimately how we conserve it. Rapid urbanization and increased infrastructure development have posed challenges on how to improve the quality of life without compromising the environment. Cities today consume 75% of the world's...
As deployment rates for new energy technologies rapidly increase, there is growing emphasis on infrastructure and systems operations upgrades that will be needed to accommodate the unique operating characteristics of new renewable, efficiency, and end-use technologies. To meet these integration challenges, the National Renewable Energy Laboratory (NREL) is implementing a comprehensive systems approach...
Increasing energy prices and the greenhouse effect lead to more awareness of energy efficiency of electricity supply. During the last years, a lot of domestic technologies have been developed to improve this efficiency. These technologies on their own already improve the efficiency, but more can be gained by a combined management. Multiple optimization objectives can be used to improve the efficiency,...
With the increasing complex operating environment of the electric power system and the ongoing electric power system reform, the traditional power grid needs to be further improved to achieve the transition to the smart grid. At the same time, the global energy and environmental problems became public concern, and the energy-efficient distribution of the power grid can effectively raise the energy...
With the energy reduction become more and more popular, power company need to build AMR system to improve energy efficiency. Many AMR systems around the world have used PLC as communication channel and it's the same in China. BPL technology has become more mature, and it's reliability, stability and practicality has been verified in a number of field trial which shows great potential in the future...
Environmental concerns and power quality delivery needs have led regulators to sponsor new programs in energy efficiency, renewable energy capacity generation, and reliability improvements. Utilities are responding to those needs. This panel addresses emerging technology to enable smart grid deployment for improving energy efficiency.
As environmental concerns and energy consumption continue to increase, utilities are looking at cost effective strategies for improved network operation and consumer consumption. Smart grid is a collection of next generation power delivery concepts that includes new power delivery components, control and monitoring throughout the power grid and more informed customer options. This session will cover...
