The Importance of Protection & Controls (P&C) and IEDs

Power-Substation-P&C-IEDs
Protection and Controls (P&C) engineering and design is extremely important in power grid protection and coordination especially with the use of intelligent electronic devices (IEDs). Proper P&C designs and coordination with protective relaying and IEDs is an essential part of electrical power engineering for protecting large expensive power equipment such as: generators, transformers, transmission lines (TLs), power circuit breakers, electrical bus, etc.

Funding boost to put Orbex on Scottish launchpad

Orbex-Space

The Engineer – Plans by Orbex to launch small satellites from Scotland have received a boost following a $24m funding round led by BGF and Octopus Ventures.

The latest investment puts the Forres headquartered company on course to the first launch from Scotland’s Space Hub Sutherland spaceport.

“Orbex is an impressive UK company which is developing a strongly differentiated and innovative launch solution for the rapidly-growing small satellite market,” saidKeith Barclay, investor at BGF. “In Europe, they are a recognised leader with an experienced team, substantial institutional support, a growing customer list and patented technology. The private space sector remains a key future industry for both Scottish and UK governments.”

Lockheed Martin to assist UK in developing vertical launch spaceport in Scotland

Orbex’s Prime rocket uses bio-propane that is claimed to cut CO2 emissions by 90 per cent compared to kerosene-based rocket fuels. Designed to be recoverable and re-usable, Orbex Prime is intended to leave no debris in the ocean or in orbit around the Earth. The company’s rocket vehicle for low-cost orbital launches is being built at factories in Forres, near Inverness, and Copenhagen in Denmark.

Green Mountain Power Deploys V2G Charger to Reduce Demand on Grid

Green-Mtn-Power-EV-Charging-Stations

T&D World – Green Mountain Power (GMP) recently announced the successful deployment of what the company says is a first-of-its kind vehicle-to-grid (V2G) charger to reduce energy use on the grid during peak demand. The GMP is the first utility to install and successfully integrate this new charger technology with the grid and one of its electric fleet vehicles to draw energy from the car to help lower demands on the grid when peaks in energy needs occur. This work shows how electric vehicles (EVs) and the clean energy they store can become a reliable source of power to reduce peak demands which will, in turn, save money and reduce carbon.

“This is an important first step in proving that V2G technology is possible. The GMP has long committed to using advancements in energy technology to increase clean energy storage capabilities so that we can deploy that power when it’s needed the most to reduce carbon and costs for all customers,” said Mari McClure, the GMP’s president and CEO.

Major Solar Storms That Could Effect the Earth

Solar-Storms

Washington Post – After a lengthy slumber, the sun is waking up, crackling with activity and hurling blistering pulses of energy into space. Solar physicists are expecting an uptick in stormy “space weather,” with implications that affect us here on Earth.

As soon as Thursday, the National Oceanic and Atmospheric Administration is predicting that a solar outburst could generate northern lights or aurora as far south as Oregon to Pennsylvania.

This flare-up coincides with the onset of “Solar Cycle 25,” an 11-year window within which storminess on the surface of the sun peaks and “solar storms” become routine.

The sun is nearly 93 million miles away, but disturbances on its surface can have serious effects far and wide across the solar system. Solar scientists and forecasters of space weather track “sunspots,” or cool, discolored regions that make appearances on the solar disk. The number of sunspots present at any given time fluctuates over the course of 11 years, each span representing one cycle.

Sunspots are often the source of solar flares, which can cause high-frequency radio blackouts and interrupt communications on Earth. At the same time, sunspots may also release coronal mass ejections, which are sneeze-like eruptions of magnetic energy, that can bring about occasionally epic displays of the northern lights.

Companies Announce New Residential Virtual Power Plant for California

distributed-power

(PowerMag) – A distributed energy power plant, designed to help bring more reliability to California’s power grid, is being developed by a company whose investors include Alphabet, the parent company of Google. The project when fully developed would be the world’s largest residential virtual power plant (VPP).

Sidewalk Infrastructure Partners (SIP), a group that builds, owns, operates, and invests in advanced infrastructure projects and technology companies, on Dec. 7 released details of a $100 million deal as part of Resilia, the company’s new advanced power grid platform. The agreement includes an $80 million commitment to finance the 550-MW Resi-Station project, along with a $20 million investment in OhmConnect, a partner in the VPP.

Growth of VPP installations has accelerated, particularly in areas that have sustained rolling blackouts and power outages. A project in South Australia, with Tesla taking a lead role, was touted as the world’s largest VPP when development began in 2018.   

OhmConnect is a demand response and energy services technology company that works with residential electricity customers to predict, incentivize, and coordinate consumer energy savings. Resi-Station is expected to bring together thousands of electricity customers with in-home smart devices that can deliver targeted energy reductions supported by OhmConnect’s technology, according to SIP. The project’s investors also include the Ontario Teachers’ Pension Plan, based in Toronto, Canada, which has long been a financial supporter of institutional infrastructure projects.
