Smart Grid

“Smart grid” generally refers to a class of technology people are using to bring utility electricity delivery systems into the 21st century, using computer-based remote control and automation. These systems are made possible by two-way communication technology and computer processing that has been used for decades in other industries. They are beginning to be used on electricity networks, from the power plants and wind farms all the way to the consumers of electricity in homes and businesses. They offer many benefits to utilities and consumers -- mostly seen in big improvements in energy efficiency on the electricity grid and in the energy users’ homes and offices. For a century, utility companies have had to send workers out to gather much of the data needed to provide electricity. The workers read meters, look for broken equipment and measure voltage, for example. The “grid” amounts to the networks that carry electricity from the plants where it is generated to consumers.

Grid or Off-Grid? Bob Bruninga, WB4APR If you have no access to the GRID, you have no choice, you have to go ... off-grid! But if you have the grid and are considering going off-grid or using batteries for any reason, please review this page and also join our discussion group. Click to join SolarDIY Download Solar Presentation given at the 2011 TAPR/AMSAT dinner at Dayton. PowerMeter - Save Energy. Save Money. Make a Difference. We launched Google PowerMeter as a free energy monitoring tool to raise awareness about the importance of giving people access to their energy information. PowerMeter included key features like visualizations of your energy usage, the ability share information with others, and personalized recommendations to save energy. We partnered with device manufacturers and utilities around the world.

Creating a Microgrid Energy Management System Using NI LabVIEW and DAQ - Solutions Author(s):Cheah Peng Huat - 南洋工科大学 Siow Lip Kian - 南洋工科大学 Liang Hong Zhu - 南洋工科大学 Vo Quoc Nguyen - 南洋工科大学 Nguyen Dinh Duc - 南洋工科大学 Gooi Hoay Beng - 南洋工科大学 Students at the Laboratory for Clean Energy Research (LaCER) in the School of Electrical and Electronic Engineering (EEE) at Nanyang Technical University (NTU) created a microgrid prototype. It consists of energy resources such as solar photovoltaics (PVs), wind turbines, fuel cells, and battery banks.

Texas Electricity Ratings: The Blog This morning Direct Energy has announced their purchase of Texas retail electricity provider Bounce Energy. Bounce Energy, who has consistently been at the top of the Texas Electricity Ratings rankings (currently #1), has easily been the most innovative electricity provider in the country in terms of their online technology/capabilities and their success in reaching out to potential and existing customers through social media outlets. Additionally, just recently, Bounce made groundbreaking contributions to the electricity space with the launch of their new MyAccount functionality, as well as their Build Your Own Plan functionality. The Build Your Own Plan is the only one of it’s kind in the electricity space, and allows customers to select their own plan term length, the amount of renewable energy in the plan, whether they want automated and paperless billing, and more. All in all, it’s a very interesting day for Texas electricity customers.

Test of building smart sensors yields big energy savings (PhysOrg.com) -- To reduce energy consumption in commercial buildings, computer scientists at the University of California, San Diego have come up with a way to use real-time occupancy sensors and computer algorithms to create smart heating, ventilation and air-conditioning (HVAC) systems. Based on early test results, the software- and sensor-based solution produced electrical energy savings of between 9.54 and 15.73 percent on their test deployment on one floor of a 5-floor campus building. “It’s clear that sensors and computing are key to reducing the demand for electricity in office buildings,” said Yuvraj Agarwal, a research scientist in UC San Diego’s Computer Science and Engineering (CSE) department. “Based on the test deployment, we estimate 40-50 percent in energy savings if we deployed our system across the entire CSE building. This is done because there is currently no easy and cost-effective way of knowing when individual occupants arrive in or leave their offices.

Energy Manager Design for Microgrids On-site energy production, known as distributed energy resources (DER), offers consumers many benefits, such as bill savings and predictability, improved system efficiency, improved reliability, control over power quality, and in many cases, greener electricity. Additionally, DER systems can benefit electric utilities by reducing congestion on the grid, reducing the need for new generation and transmission capacity, and offering ancillary services such as voltage support and emergency demand response. Work within the CERTS DER team at the Ernest Orlando Lawrence Berkeley National Laboratory has led to development of software tools for microgrid design and operation. The DER Customer Adoption Model (DER-CAM) chooses economically optimal sets of DER devices to install for a given site. Additionally, the Site Energy Supply and Use Model (SESU) simulates operation of an installed microgrid and can be used as a testing ground for proposed EM strategies.

Monitor Your Home Power Usage by Building a DIY Power Meter Reader - How-To Geek ETC Commercial meter readers are expensive; this DIY hack allows you to cheaply monitor your power consumption for a greener tomorrow (and, realistically, a much lower bill). Paul discovered that his digital power meter sent out a pulse of IR light every time a watt-hour of power was consumed. He built a simple monitoring assembly in a project box that consisted of a small circuit board and a photo transistor. It’s a clever and inexpensive hack (it cost him less $20). You can check out the details of his build at the link below. Don’t have a digital meter?

Active Filters for Video Abstract: Originally, video filters were passive LC circuits surrounded by amplifiers. Smaller, more efficient designs can currently be achieved by combining the amplifier with an RC filter. Sensitivity analysis and predistortion methods developed in the 1960s have, moreover, overcome the poor performance that gave early video filters a bad reputation. High-performance op amps and specialized software for the PC enable the design of wide-bandwidth active filters, but those advantages do not address the requirements of any specific application. For video filters, the particular application and signal format add nuance to each circuit design.

What Is A Smart Solar Inverter? Smart microinverters can help meet advanced grid functionality and operations & maintenance requirements. By: Raghu Belur, SPW Contributor The growth of the U.S. solar market over the past five years has been remarkable, with the total number of photovoltaic installations climbing into the hundreds of thousands. This is impressive, but it’s still just a drop in the bucket compared to the tens of millions of rooftop and ground-mount PV systems that will be deployed during the next few decades.
