Micro smart grid technology provides a desirable infrastructure for energy efficient buildings. In additional to the power source from the grid, a micro grid for buildings may contain autonomous power generators possibly CHP, renewable energy resources such as PV solar cells, power storage devices and system loads including HVAC systems, lighting equipment, IT data centers, etc. With support of a...
Load Signature is the unique consumption pattern intrinsic to each individual electrical appliance/equipment. This paper focus on building a universal platform to better understand and explore the nature of electricity consumption patterns using load signatures and advanced technology, such as feature extraction and intelligent computing. Through this knowledge, we can explore and develop innovative...
With the increase of distributed generation (DG) connections, circuit overload and voltage violation will occur for some distribution networks. However, building new lines to accommodate DG may pay high monetary and environment costs. A new procedure of distribution network reinforcement taking the active management means into consideration is proposed in this paper. Models and solution methods for...
Hybrid renewable energy systems are demonstrated around the world. Some of the systems can be operated in both on-grid and off-grid modes. Some other systems are operated in on-grid mode, but try to minimize the electricity flow as much as possible. Demonstrations in Japan, Hawaii, Norway, and other areas are introduced as examples of the hybrid renewable energy systems.
This paper presents a smart metering network for monitoring energy consumption and power quality of building integrated electric vehicle charging network. The smart metering network consists of smart metering devices, a ZigBee communication network, and a central system for power calculation and power quality analysis. The smart metering device captures current and/or voltage waveform and performs...
A system based on Artificial Neural Network (ANN) for load predication in power distribution system with chillers is presented in this paper. The proposed system could predict the chillers' load each hour in a day by using the weather conditions as input. Results from this system provide possibility to improve the power factor of the chillers system and to optimize the power distribution in loads...
This paper presents a practical approach in which smart meters with communication ports for third party integration in a high rise building that could be supplied with distributed energy sources, and can share the data to both local building management system and the utilities at the same time. Some examples will be used to demonstrate the capability of the approach.
In the Indian power scenario Demand Side Management or DSM as popularly known has assumed a significant role in the recent five-year plans. Over the years power development has seen generation addition manifold along with expansion in transmission and distribution system. Optimum utilization of resources in overall sense, however, calls for managing the demand also for proper capacity utilization...
In urban areas, where land is costly, building integrated wind energy conversion systems can be embedded into the existing infrastructure to meet an increasing load demand. Recently small scale wind turbines (less than 10kw) are installed in great numbers on the roof-top of residential houses, commercial and high rising buildings. This paper presents an overview of the current technologies being implemented...
This paper describes architectural and engineering design features of the “Sustainable Energy Research Facility (SERF)” to be constructed on Frostburg State University campus located in Western Maryland, USA. SERF will be an off-grid, energy efficient, residential size building supplied by clean renewable energy sources. When completed, SERF will be used by the FSU Renewable Energy Center to offer...
This paper illustrates the problems associated with using Norton equivalent models to represent single-phase nonlinear loads. The study is conducted with a specially-developed harmonics testing station that uses feedback to drive the load voltage to a desired target waveform. We apply various voltage waveshapes with 5% THDv to several types of single-phase nonlinear loads which allow us to compute...
Within the context of recent interest in `Smart Grids', this paper considers the possibility that domestic consumers could participate in demand side management. Price is one of the main concerns for domestic consumers, and hence Real Time Pricing (RTP) can have an influence on consumers with dispatchable generation such as micro combine heat and power (micro-CHP). These systems can reduce the annual...
It is generally believed that plug-in electric vehicles (PEVs) offer environmental and energy security advantages compared to conventional vehicles. Policies are stimulating electric transportation deployment, and PEV adoption may grow significantly. New technology and business models are being developed to organize the PEV and building interface and their interaction with the wider grid. This paper...
Sustainability is the next significant trend to confront government agencies as evidenced by the world-wide focus on energy conservation and reducing green house gases. Recent environmental laws and legislation require agencies to address conservation in very specific ways. Given this goal of sustainability, what strategies initiatives, and measures can be implemented? One answer is the adoption of...
